Organization

A Special Reservist had an initial six months full-time training and was paid the same as a regular soldier during this period; they had three or four weeks training per year thereafter. The National Reserve had some 215,000 men, who were on a register that was maintained by Territorial Force County Associations; these men had military experience, but no other reserve obligation, and only some 60,000 were classified as willing or able to serve an active role at home or abroad. The regulars and reserves—at least on paper—totalled a mobilised force of almost 700,000 men, although only 150,000 men were immediately available to be formed into the British Expeditionary Force (BEF) that was sent to the continent.

Over the course of the war, the composition of the infantry division gradually changed, and there was an increased emphasis on providing the infantry divisions with organic fire support.

s in four companies of 16 guns. Each brigade in the division also had a mortar battery with eight Stokes Mortars. The artillery also changed the composition of its batteries. At the start of the war, there were three batteries with six guns per brigade; they then moved to four batteries with four guns per brigade, and finally in 1917, to four batteries with six guns per brigade to economise on battery commanders. In this way, the army would change drastically over the course of the war, reacting to the various developments, from the mobile war fought in the opening weeks to the static trench warfare of 1916 and 1917. The cavalry of the BEF represented 9.28% of the army; by July 1918, it would only represent 1.65%. The infantry would decrease from 64.64% in 1914 to 51.25% of the army in 1918, while the Royal Engineers would increase from 5.91% to 11.24% in 1918.

The Third Army was formed in July 1915 and with the influx of troops from Kitchener's volunteers and further reorganisation, the Fourth Army and the Reserve Army, which became the Fifth Army were formed in 1916.

By January 1916, when conscription was introduced, 2.6 million men had volunteered for service, a further 2.3 million were conscripted before the end of the war; by the end of 1918, the army had reached its peak strength of four million men. Analysis of death records from the Hundred Days (August - November 1918) suggests that around 60% of those who died were conscripts (many of the men "combed out" from rear echelon jobs and posted to the front lines in 1917-18 had volunteered earlier in the war), and that despite the recent lowering of the age limit for service on the Western Front from nineteen to eighteen-and-a-half, the average age of the dead was still in the mid-twenties. Alison Hine comments that although incompleteness of records makes it hard to say whether these dead men were a representative sample of the BEF as a whole, assertions that the late-war BEF consisted largely of conscripted "boys" should therefore be treated with caution. Furthermore, although there were certainly many cases of men being sent to regiments from parts of the country other than their own, many battalions were still filled with men from their traditional local areas, the same as earlier in the war. Caution therefore should be employed before accepting claims that there was a deliberate attempt to "destroy the Regiment … and nationalise the Army" (e.g. by Dunn in ''The War The Infantry Knew'' (1938)). Women also volunteered and served in a non-combatant role; by the end of the war, 80,000 had enlisted. They mostly served as nurses in the

Officer selection

In August 1914, there were 28,060 officers in the British Army, of which 12,738 were regular officers, the rest were in the reserves. The number of officers in the army had increased to 164,255 by November 1918. These were survivors among the 247,061 officers who had been granted a commission during the war.

education was almost essential. In 1913, about 2% of regular officers had been promoted from the ranks. The officer corps, during the war, consisted of regular officers from the peacetime army, officers who had been granted permanent commissions during the war, officers who had been granted temporary commissions for the duration of the war, territorial army officers commissioned during peacetime, officers commissioned from the ranks of the pre-war regular and territorial army and temporary officers commissioned from the ranks for the duration of the war alone.Sheffield (2000), p. 29 In September 1914, Lord Kitchener announced that he was looking for volunteers and regular NCOs to provide officers for the expanding army. Most of the volunteers came from the middle class, with the largest group from commercial and clerical occupations (27%), followed by teachers and students (18%) and professional men (15%).

By this stage, it was official policy that men over 35 were no longer eligible to command battalions. This trend was reflected amongst the junior officers.

s, there was a greater emphasis on advancing in extended order, the use of available cover, the use of artillery to support the attack, flank and converging attacks and fire and movement. The Army expected units to advance as far as possible in a firing line without opening fire, both to conceal their positions and conserve ammunition, then to attack in successive waves, closing with the enemy decisively. The cavalry practised reconnaissance and fighting dismounted more regularly, and in January 1910, the decision was made at the General Staff Conference that dismounted cavalry should be taught infantry tactics in attack and defence. They were the only cavalry from a major European power trained for both the mounted cavalry charge and dismounted action, and equipped with the same rifles as the infantry, rather than short-range

The infantry's marksmanship, and fire and movement techniques, had been inspired by Boer tactics and was established as formal doctrine by Colonel Charles Monro when he was in charge of the School of Musketry at Shorncliffe. In 1914, British rifle fire was so effective that there were some reports to the effect that the Germans believed they were facing huge numbers of machine guns. The Army concentrated on rifle practice, with days spent on the ranges dedicated to improving marksmanship and obtaining a rate of fire of 15 effective rounds a minute at ; one sergeant set a record of 38 rounds into a target set at in 30 seconds.Jarymowycz & Starry (2008), p. 124 In their 1914 skill-at-arms meeting, the 1st Battalion

This company had 10 Vickers guns; it was ordered to give sustained covering fire for 12 hours onto a selected area away, to prevent German troops forming up there for a counterattack while a British attack was in progress. Two companies of infantry were allocated as ammunition, rations and water carriers for the gunners. Two men worked a belt–filling machine non–stop for 12 hours, keeping up a supply of 250-round belts. They used 100 new barrels and all of the water—including the men's drinking water and the contents of the

buckets—to keep the guns cool. In that 12-hour period, the 10 guns fired just short of one million rounds between them. One team is reported to have fired 120,000. At the close of the operation, it is alleged that every gun was working perfectly and that not one had broken down during the whole period. The lighter Lewis gun was adopted for land and aircraft use in October 1915. The Lewis gun had the advantage of being about 80% faster to build than the Vickers, and far more portable. By the end of the First World War, over 50,000 Lewis Guns had been produced; they were nearly ubiquitous on the Western Front, outnumbering the Vickers gun by a ratio of about 3:1. The Stokes Mortar was rapidly developed when it became clear that some type of weapon was needed to provide artillery-like fire support to the infantry. The weapon was fully man-transportable yet also capable of firing reasonably powerful shells at targets beyond the range of rifle grenades. Finally, the

The third was formed from small groups of reinforcements, the fourth wave was expected to defend the captured territory. All waves were expected to take advantage of the ground during the advance. (see below for when operating with tanks) Each platoon now had a Lewis gun section and a section that specialised in throwing hand-grenades (then known as bombs), each section was compelled to provide two scouts to carry out reconnaissance duties.Bull (2002), pp. 50–51 Each platoon was expected to provide mutual fire support in the attack they were to advance, without halting; but leap frogging was accepted, with the lead platoon taking an objective and the following platoons passing through them and onto the next objective, while the Lewis gunners provided fire support. Grenades were used for clearing trenches and dugouts, each battalion carried forward two trench mortars to provide fire support.


Tank tactics

The tank was designed to break the deadlock of trench warfare. In their first use on the Somme, they were placed under command of the infantry and ordered to attack their given targets in groups or pairs. They were also assigned small groups of troops, who served as an escort while providing close defence against enemy attacks.Bull (2004), p. 53 Only nine tanks reached the German lines to engage machine gun emplacements and troop concentrations. On the way, 14 broke down or were ditched, another 10 were damaged by enemy fire. In 1917, during the battle of Cambrai, the

adopted new tactics. Three tanks working together would advance in a triangle formation, with the two rear tanks providing cover for an infantry platoon. The tanks were to create gaps in the barbed wire for the accompanying infantry to pass through, then use their armament to suppress the German strong points. The effectiveness of tank–infantry co-operation was demonstrated during the battle, when Major General George Harper of the

refused to co-operate with the tanks, a decision that compelled them to move forward without any infantry support; the result was the destruction of more than 12 tanks by German artillery sighted behind bunkers.

Artillery tactics

Prior to the war, the artillery worked independently and was taught to support the infantry to ensure a successful attack. In 1914, the heaviest artillery gun was the 60-pounder, four in each heavy battery. The

used the 18-pounder gun. By 1918, the situation had changed; the artillery were the dominant force on the battlefield. Between 1914 and 1918, the Royal Field Artillery had increased from 45 field brigades to 173 field brigades, while the heavy and siege artillery of the

.Tucker (2001), p. 356 A creeping barrage could maintain the element of surprise, with guns opening fire only shortly before the assault troops moved off. It was useful when enemy positions had not been thoroughly reconnoitred, as it did not depend on identifying individual targets in advance. The idea behind the creeping barrage was that the infantry should reach the enemy positions before the defenders had time to recover, emerge from shelters, and man their positions.

. A weakness of the creeping barrage was that the infantry was subordinated to the artillery schedule, while the infantry commanders had less control over the tactical situation and were therefore in danger of forgetting how to manoeuvre their troops around the battlefield. The importance of the barrage was such that traditional infantry tactics, including a reliance on the infantry's own firepower to support its movement forward, was sometimes forgotten. Once the infantry had reached the German trenches, the artillery shifted from the creeping barrage to the standing barrage, a static barrage ahead of the infantry that would protect them from counter-attack while they consolidated the position. A variant was the
box barrage In military usage, a barrage is massed sustained artillery fire (shelling) aimed at a series of points along a line. In addition to attacking any enemy in the kill zone, a barrage intends to suppress enemy movements and deny access across tha ...
, in which three or four barrages formed a box—or more often three sides of a box—around a position to isolate and prevent reinforcements being brought up into the front line. This was normally used to protect trench raids, although it could also be used offensively against a German unit. Another type of barrage was the SOS barrage, fired in response to a German counterattack. An SOS barrage could be brought down by firing a

A Counter Battery Staff Officer (CBSO) was appointed at each corps to co-ordinate the counter battery effort, collating reports from sound ranging and Royal Flying Corps observers. By the end of the war, it was realised that the important effect of the barrage was to demoralise and suppress the enemy, rather than physical destruction; a short, intense bombardment immediately followed by an infantry assault was more effective than the weeks of grinding bombardment used in 1916.

. In open warfare, visual signalling (employing signal flags and the heliograph) was the norm. A competent signaller could transmit 12 words a minute with signal flags (during daylight) and signal lights (at night). Signal lights, which were secured in a wooden case, employed a battery-operated Morse code key. These signalling techniques had certain disadvantages, however. In trench warfare, operators using these methods were forced to expose themselves to enemy fire; while messages sent to the rear by signal lights could not be seen by enemy forces, replies to such messages were readily spotted, and operators were, once again, exposed to enemy fire. During the war, the Army also trained animals for use in the trenches. Dogs carried messages; horses, mules and dogs were used to lay telephone and telegraph cables. Carrier pigeons, who transported messages back from the front line, were also carried in tanks so that they could deliver messages during an attack. Over 20,000 pigeons and 370 handlers were used during the war, and at times, they were the sole means of communication.

(MGC) was formed to provide heavy machine-gun teams after a proposal was made to the War Office for the formation of a single specialist machine-gun company for each infantry brigade—a goal to be achieved by withdrawing guns and gun teams from the battalions. Created in October 1915, the MGC consisted of infantry machine-gun companies, cavalry machine-gun squadrons and motor machine-gun batteries. In the trenches, the Corps' guns were deployed with an interlocking field of fire and proved to be a devastating defensive weapon against attacking infantry. They were also used in an indirect fire support role, in which they fired over the heads and from the flanks of the advancing infantry and behind the German trenches to stop reinforcements and supplies from getting to the front.

In November 1916, each company was reformed as a battalion of three companies, with plans to increase the Corps to 20 battalions, each Tank Battalion had a complement of 32 officers and 374 men. Tanks were primarily used on the Western Front. The first offensive of the war in which tanks were used ''en masse'' was the battle of Cambrai in 1917; 476 tanks started the attack, and the German front collapsed. At midday the British had advanced five miles behind the German line. The battle of Amiens in 1918 saw the value of the tank being appreciated; 10 heavy and two light battalions of 414 tanks were included in the assault. 342 Mark Vs and 72

were backed up by a further 120 tanks designed to carry forward supplies for the armour and infantry. By the end of the first day of the attack, they had penetrated the German line by , 16,000 prisoners were taken. In September 1918, the British Army was the most mechanised army in the world. Some 22,000 men had served in the Tank Corps by the end of the war. A detachment of eight obsolescent Mark I tanks was sent to Southern Palestine in early 1917 and saw action against Turkish forces there.


Army Service Corps

The Army Service Corps (ASC) operated the transport system to deliver men, ammunition and matériel to the front. From 12,000 men at the start of the war, the Corps increased in size to over 300,000 by November 1918. In addition they had under command Indian, Egyptian, Chinese (

Life in the trenches

By the end of 1914, the war on the Western Front had reached stalemate and the trench lines extended from the Belgian coast to the Swiss frontier. By September 1915, the length of the British front line stretched some . Soldiers were in the front or reserve line trenches for about eight days at a time, before being relieved. There were three trenches in a typical front line sector; the fire trench, the support trench and the reserve trench, all joined by communication trenches. The trenches varied in depth, but they were usually about four or five feet deep, or in areas with a high

The men were then expected to sleep wherever they could and in wet weather they lived under groundsheets or in tents at the bottom of the trench on the duckboards. At the front, soldiers were in constant danger from artillery shells, mortar bombs and bullets and as the war progressed they also faced aerial attack. Some sectors of the front saw little activity throughout the war, making life comparatively easy. Other sectors were in a perpetual state of violent activity. However, quiet sectors still amassed daily casualties through

Food could not usually be cooked in the front line trenches as any smoke would draw enemy fire, hot food had to be carried along communication trenches in clumsy "hayboxes", sometimes arriving late or not at all.


Daily routine

Daily routine of life in the trenches began with the morning 'stand-to'. An hour before dawn everyone was roused and ordered to man their positions to guard against a dawn raid by the Germans. With stand-to over, it was time for the men to have breakfast and perform ablutions. Once complete, the NCOs would assign daily chores, before the men attended to the cleaning of rifles and equipment, filling sandbags, repairing trenches or digging latrines. Once the daily tasks had been completed the men who were off-duty would find a place to sleep. Due to the constant bombardments and the sheer effort of trying to stay alive,

was common. Soldiers also had to take it in turns to be on sentry duty, watching for enemy movements. Each side's front line was constantly under observation by snipers and lookouts during daylight; movement was therefore restricted until after the dusk stand-to and night had fallen. Under the cover of darkness, troops attended to vital maintenance and resupply, with rations and water being brought to the front line, fresh units swapped places with troops moving to the rear for rest and recuperation.

Moving into the front line

A set procedure was used by a division that was moving into the front line. Once they had been informed that they were moving forward, the brigadiers and battalion commanders would be taken to the forward areas to reconnoitre the sections of the front that were to be occupied by their troops. Meanwhile, the battalion transport officers would be taken to the headquarters of the division that they were relieving to observe the methods used for drawing rations and ammunition, and the manner in which they were supplied to the troops at the front. Detachments from the divisional artillery group would move forward and were attached to the artillery batteries of the division they were relieving. Five days later, the infantry battalions that were destined for the front line sent forward their specialists from the Lewis gun teams, and the grenade officer, the machine gun officer, the four company commanders, and some of the signallers to take over the trench stores and settle into the trench routine before the battalions moved in. Overnight, the battalions would move into the line, and the artillery would take over the guns that were already in position, leaving theirs behind to be taken over by the batteries that had been relieved.


Discipline


Legal authority

of 1688 the Crown has not been permitted a standing army in the United Kingdom – it derives its existence from the Army Act, passed by Parliament each year (every five years since the late 1950s). The House of Commons took these responsibilities seriously: a letter from Haig clarifying the position on shell-shock had to be read out in the House of Commons on 14 March 1918. Most disciplinary regulations in the First World War derived from the 1881 Army Act, although some offences were more severely dealt with on active service, e.g. in principle looting or wilful disobedience carried the death penalty.


Lesser offences

Lesser offences were dealt with by commanding officers. For petty offences, a company commander could have men fined or confined to barracks for fatigue duty A battalion Commanding Officer could give detention, order up to 28 days Field Punishment, or demote corporals to the ranks (officers and senior NCOs were dealt with by court martial other than for very trivial offences).Holmes 2004, p. 558 Other ranks could also lose leave or seniority.

(FP) had replaced flogging (abolished at home in 1868 and on active service in 1881, although still used in military prisons until 1907). FP No.1 (in which the man was shackled to fixed object, e.g. a large wheel) was awarded to 60,210 cases, equivalent to one man in 50 (although in practice there were many repeat offenders). FP No.1 could be very unpleasant depending on the weather, was abhorred by some as barbaric, and in some units was ritualised (e.g. by locking a man in a shed and throwing the handcuffs in with him); there were also cases of Australian troops releasing British troops whom they found tied up, although in other units it was regarded as a necessary sanction for serious offences. FP No.2 meant that a man was shackled but not fixed in place.Corrigan 2002, p. 225 Striking an inferior was an offence but it was not uncommon in some units for officers to turn a blind eye to NCOs keeping discipline by violence, or even to do so themselves.


Courts martial

Men who committed serious offences were tried by Field General Court Martial, sometimes resulting in execution. Despite "assertions" that these were "kangaroo courts" (e.g. in the book "Shot at Dawn" which says that men "did not receive even the rudiments of a just hearing") the release of records in 1990-4 showed this to be untrue. They in fact had strict rules of procedure and a duty to uncover the facts.Holmes 2004, p. 563. Unlike a General Court Martial in peacetime, there was no legally qualified Judge-Advocate to advise the court, but from the start of 1916 a "Court Martial Officer" – usually an officer with legal experience in civilian life – was often present to do so.Holmes 2004, p. 561. The accused was entitled to object to the composition of the panel (e.g. if one of the officers was connected with the case or enjoyed a poor relationship with the accused) and to present his case, defended by an officer (a "Prisoner's Friend") if he chose, although "Prisoners Friends" became more common as the war went on.Bond & Cave 2009, p. 201 The officer who convened a court martial could not sit on it, and the most junior officer voted first (to lessen the chance of his deferring to a superior's opinion). However, the courts were explicitly intended to be "speedy" and were sometimes encouraged by higher authority to make an example of certain offences, and in practice the leniency of the court and the ability of the accused to defend himself varied widely. Some pleaded guilty or chose not to present a defence or call witnesses, and in most cases the offence was "so blatant that little defence could be put forward". Eighty-nine per cent of courts martial returned a guilty verdict, the vast majority of cases being for offences such as Absence Without Leave (the most common offence), drunkenness and insubordination. Terms of imprisonment were often suspended, to discourage soldiers from committing an offence to escape the front lines, but also to give a convicted man a chance to earn a reprieve for good conduct.Holmes 2004, p. 565 Of the 252 officers tried, 76 per cent were found guilty, the most common offence (52 per cent of cases) being drunkenness. Although three officers were executed, an officer was most likely to receive a severe reprimand (60 per cent of cases – a severe blow to his career) or be cashiered (30 per cent of cases – stripped of his commission, which brought total social disgrace and barred him from any employment under the Crown, even working for the local council – but a cashiered officer could still be conscripted as a private to a different unit).


Executions

A death sentence had to be passed unanimously, and confirmed in writing by various officers as the verdict passed up the chain of command. A man's battalion and brigade commander tended to comment on his own record, but senior generals tended to be more concerned with the type of offence and the state of discipline in that unit.Bond & Cave 2009, p. 202 The Judge Advocate General at GHQ also checked the records for irregularities, before final confirmation (or otherwise) by the Commander-in-Chief of the relevant theatre.Corrigan 2002, p. 232 Of the 3,080 men sentenced to death, 346 men were actually executed, the vast majority of these (266) for desertion, the next largest reasons for execution being murder (37 — these men would probably have been hanged under civilian law at the time) and cowardice (18).Corrigan 2002, p. 230 Convictions for mutiny were rare — only one man was shot for the Etaples disturbances in 1917. Of the men shot, 91 were already under a previous suspended sentence, and nine under two sentences. Of the 91, 40 were already under a suspended death sentence, 38 of them for desertion, and one man had already been "sentenced to death" twice for desertion. It was felt at the time that, precisely because most soldiers in combat were afraid, an example needed to be made of men who deserted. Front line soldiers also sometimes felt that those who left their mates "in the lurch" by deserting "deserved to be shot".Holmes 2004, p. 559 One historian writes that there is "virtually no evidence" that soldiers thought the death penalty unjust, although another writes that some soldiers deplored the death penalty, while most thought it justified. Desertion normally meant an absence of 21 days or other evidence to indicate intent of not returning, e.g. wearing civilian clothes or failing to report for a key deployment. Those executed were normally not boys – the average age was in the mid-twenties and 40 percent had been in serious trouble before. Thirty percent were regulars or reservists, 40 percent were Kitchener volunteers, 19 percent were Irish, Canadian or New Zealand volunteers, but only nine percent were conscripts, suggesting indulgence to the conscripts, many of them under 21, who made up the bulk of the army by late in the war. Only executed men's records survive, so it is hard to comment on the reasons why men were reprieved, but it has been suggested that the policy of commuting 90 percent of death sentences may well have been deliberate mercy in the application of military law designed for a small regular army recruited from the rougher elements of society. Only 7,361 of the 38,630 desertions were in the field. Most were away from the front line — 14 of the executed deserters were arrested in the United Kingdom — and many deserters had never served in the front line at all. In the latter part of the war, executed men's families were usually told white lies by the authorities; their families received pensions, and the men were buried in the same graves as other dead soldiers. Death for desertion was abolished in 1930 over objections in the

, were made an example of because they were found sitting asleep together, suggesting that they had colluded). Australians made up seven percent of the British Expeditionary Force but 25 percent of deserters, while an Australian was nine times more likely to be imprisoned than a British soldier. Haig asked for permission to shoot Australians, but their government refused. British discipline of the First World War was not especially severe compared to most other armies of the time (e.g. the Russians and Italians). The French admitted to only 133 executions and the Germans 48, but these figures may not be reliable as both armies had problems with discipline.

" because it was initially wrongly thought to be caused by concussion damage to the membranes of the brain) was beginning to be recognised and was - in principle - admissible in defence; it was classified as a war injury, although there were concerns that soldiers accused of offences tried falsely to claim shell shock as a defence. One historian writes that "in no case was a soldier whom the medical staff certified as suffering from shell shock actually executed", that "there appear to have been very few cases where men who alleged shell shock, but whose claim was denied, were actually executed", and that the suggestions of modern campaigners that most of the executed men suffered from shell shock are "palpably untrue". However, another historian has pointed out that there was a great deal of chance in whether a soldier's claim of shell-shock would be taken seriously, and gives examples of soldiers being given cursory medical examinations or none; specific references to shell-shock are uncommon, and records usually refer to dizziness, "queer turns", bad nerves etc. Such trauma was still poorly understood at that time. There were enquiries in 1919, 1922, 1925 and 1938, which examined documents now lost and witnesses now dead. The books "For the Sake of Example" (1983) by Babington and "Shot at Dawn" (1989) by Sykes & Putkowski were openly intended to start a campaign for pardons. This campaign was rejected in February 1993 because there was no evidence of procedural error (i.e. they had been correctly convicted according to the law at the time) and it was felt not right to impose modern values on to the past. The case was rejected again in 1998 after a detailed two-year review, which found "no white cases, very many black cases and a handful of grey cases" in which medical evidence was ignored or not called. The decisions were reversed by the Government in 2006 and all men given pardons and recognised as victims of the First World War. However, their sentences were not overturned as it was impossible after this length of time to re-examine the evidence in every case.


Other discipline

It has been pointed out that there are only anecdotal accounts, and no figures, for men who were shot on the spot by officers and NCOs for "cowardice in the face of the enemy". There were over 13,000 Royal Military Police ("redcaps"). They were unpopular, at a time when the police were often unpopular with young men from big cities. Besides policing, a large part of their job was maintaining discipline on the march and keeping roads running smoothly, and collecting stragglers from a battle. During the March 1918 retreat 25,000 stragglers were rounded up and sent back to fighting units. Royal Military Police also fought on occasion if headquarters areas were threatened by an enemy advance. Soldiers sometimes told lurid tales of men who refused to fight being shot by Military Police. Historian Richard Holmes wrote that no reliable first-hand accounts exist of such events happening. There were occasional examples of men making unwanted homosexual advances, homosexuality being then criminal under both military and civil law, to escape the front lines, but prosecutions for this crime were rare, and there is also evidence of men turning a blind eye to homosexual relationships.


Positive motivation

Men were also motivated by positive means. New medals were instituted: the Military Cross was created in December 1914 for warrant officers and officers up to captain, the Military Medal for other ranks in March 1916 (although to the regret of some men, it did not carry a cash bounty like the Distinguished Conduct Medal). The Order of the British Empire (of which the MBE is one grade) was instituted in 1917. By 1918, medals for bravery were often awarded within a week to ensure that the man lived long enough to receive it. Race meetings, concert parties (including drag acts – good drag queens were in great demand), trips to the seaside and football matches were organised to keep men entertained. There were various unofficial publications, including the "Wipers Times" – these give an insight into the views of ordinary soldiers and junior officers. Overt patriotism was rare, and politicians such as (Prime Minister)
H. H. Asquith Herbert Henry Asquith, 1st Earl of Oxford and Asquith, (12 September 1852 – 15 February 1928), generally known as H. H. Asquith, was a British statesman and Liberal Party politician who served as Prime Minister of the United Kingdom f ...

Middlebrook commented that it is hard to generalise about the state of British morale, as it varied a great deal between units, with former regular and territorial units probably retaining a core of motivated men. Whereas other armies had problems with discipline, apart from the Etaples mutiny British discipline generally held up, both in combat and out of it.
