From 14 to 15 February and on 2 March 1916, the Germans and the British fought for control of the Bluff, the Germans capturing the mound and defeating counter-attacks only for the British to recapture it and a stretch of German front line, after pausing to prepare a set-piece attack.

. The BEF was at a tactical disadvantage, on low boggy ground, easily observed from German positions. A retirement to more defensible ground was impossible but rather than conserving manpower and resources with a tacit truce, the British kept an active front and five of the German local attacks in the period were retaliation for three British set-piece attacks. The Germans had better weapons and with a homogenous army, could transfer troops and equipment along the Western Front easier than the Franco–British. The German army still had many pre-war trained officers NCOs and soldiers; the British wartime volunteers gained experience in minor tactics but success usually came from firepower; in the underground war, the BEF tunnellers overtook the Germans in technological ability and ambition. Capturing a portion of the opposing front line proved possible but holding it depended on the opponent. When the Bluff was captured, the British retook it; at the

The 17th (Northern) Division had relieved the 3rd Division from on a either side of the Ypres–Comines Canal, with the 52nd Brigade on the south side responsible for the canal, the Bluff and New Year Trench on the north side and the 51st Brigade further north. The only crossing of the canal was a plank bridge some distance back from New Year Trench and although the rule that a topographical feature going through a position should not be used as a unit boundary was followed, only a platoon of the 10th Battalion, Lancashire Fusiliers held the Bluff, the rest of the battalion being on the south bank. The 50th Brigade was in V Corps reserve which left only one battalion in reserve for the 17th (Northern) Division. The 51st Brigade held a front with three battalions and one in reserve, half kept ready for an immediate counter-attack if the Bluff was captured. On battalion was moving up to relieve one of the front battalions, its bombers (after complaints from the

, hand grenade specialists had been renamed bombers, who had recently been issued with steel helmets) and Lewis gunners having arrived on 13 February. During the relief, the Bluff was the responsibility of another brigade and two battalions were mixed up; the brigade machine-gun companies, which had joined the division the day previous, were still behind the front line. On the morning of 14 February, the left flank of the 52nd Brigade at the canal and the fronts of the 51st Brigade and the rest of the V Corps front to the north, were subjected to several bombardments by German heavy artillery and after the shelling of the 51st Brigade and the 24th Division front at Hooge increased. The platoon of the 10th Lancashire Fusiliers on the Bluff took cover in The Tunnel, formerly a German mine gallery from the Bluff to the canal. Trench mortar and howitzer fire, which was usual before an infantry attack led the defenders to request heavy artillery support.


Action


14–16 February

By the British front parapet had been demolished and a mine detonation buried the party sheltering in The Tunnel, killing all but three men; two mines were blown on the left of the 10th Sherwood Foresters (10th Sherwood) on the left of the 51st Brigade. IR 124 attacked on a front from the canal to a feature known as the Ravine, a stream parallel to the canal. The British front line was captured by and by all objectives had been taken, apart from a machine-gun post at the junction of trenches A platoon sent to replace the men trapped in The Tunnel were all killed and the Bluff was captured, as were the front trenches of the 10th Sherwood Foresters. Some German troops pressed on to the British support trenches but were repulsed. Parties of IR 124 also got into trenches and the Ravine on the left, held by the 8th South Staffordshire. The Germans were also quickly forced back but the two companies reserved for an instant counter-attack on the Bluff were delayed by a command mix up, the men went forward piecemeal and conducted an indecisive bombing fight with the Germans for the rest of the night. By IR 124 held the Bluff and the 51st Brigade line from the canal to the Ravine. During the afternoon the 52nd Brigade was relieved of responsibility for the north bank and two battalions of the 50th Brigade were sent forward for a counter-attack against the Bluff. During the night bombing attacks were made but attempts to follow up with infantry failed; at on 16 February, the British commanders accepted that the counter-attacks were futile and that it would take a set-piece attack to dislodge the Germans. Plumer gave the task to troops who knew the ground and on the night of the 76th Brigade (Brigadier-General Ernest Pratt) of the 3rd Division, which had been resting out of the line, took over with attached artillery and engineers from the 51st Brigade and began to consolidate a new line. The ground had been smashed up by artillery-fire, was cut with derelict trenches and the Bluff was enclosed by the canal and a stream on the north side which made the ground swampy. The terraces adjoining the canal limited a frontal approach to an embankment wide but which tapered to , with no cover and visible from the German defences on the south side of the canal.


17 February – 1 March

The 76th Brigade planned to attack against the width of the lost trenches at dusk, to have the maximum time for consolidation, preferably on 29 February. Both sides kept up the bombardment and German casualties were so severe that IR 124 was relieved from 20 to 22 February by Grenadier Regiment 123 (GR 123), which found that the German defences had been destroyed and had to take post in scraps of trench and shell-holes, living up to the waist in water. Over the nights of the 76th Brigade was relieved by the 52nd Brigade to rest for the attack and its four battalions were equipped with steel helmets, along with two battalions of the 51st Brigade attached for the operation. The force practised on a replica of the German positions copied from aerial photographs, as the 52nd Brigade laboured on jumping-off trenches in the remnants of a sheltered wood, communication trenches, burying telephone cables and carrying ammunition and stores. German artillery bombardments slowed the work; stormy weather and then snowfalls from 27 February outlined the new trenches and on 28 February, the attack was put back to 2 March, after the cold and snow ended with a thaw which turned the ground into slush; the following days were cold and wet with sleet and snow. The attackers could not wait for 15 to 18 hours but a dusk attack meant moving up the night before. Pratt wanted a long preparatory bombardment and Brigadier-General Herbert Uniacke, the corps artillery commander, proposed a surprise attack with no preliminary artillery-fire. The commanders agreed a plan to bombard the German defences until the original zero hour at dusk, cease fire, move up the attack force overnight and attack after a 90-minute dawn bombardment. No date set because of the weather and incomplete artillery registration but the attack would occur on the second morning after a day with good enough weather to finish registering the guns. As the front line curved eastwards north of the 17th (Northern) Division, four heavy guns were dug in and camouflaged on Observatory Ridge, to fire along the Germans trenches during the attack. Plumer suggested that the 90-minute bombardment be dispensed with for surprise and at a conference it was agreed that there should be a bombardment at on 1 March for then a lift and a barrage to simulate an attack. After a cessation of the bombardment, Pratt was to decide at if there was to be a 20-minute bombardment before the attack, depending on the German response. The British attack was to capture more than had been lost, by digging a new line across a feature known as the Bean to protect a re-entrant in the old front line. The right-hand battalion was to retake New Year Trench, the Bluff and Loop Trench, the central and left-hand battalions to attack further north. Each battalion had attached sections of the 56th and East Riding companies RE and tunnelling parties. A battalion was in support of the right-flank battalion and another support battalion was to be available to all three, with two companies behind the centre battalion and a battalion in reserve. On the far right of the attack a raiding party was to demolish any German mine shafts found along the canal bank. Nine -inch, ten 2-inch, four 3-inch Stokes mortars and three 4-inch Stokes mortars were placed in groups on either side of the canal; the bombardment began on 1 March and the Stokes mortars were able to hit areas that the howitzers could not reach. Observation revealed that nearly all the German defences on the Bluff had been destroyed but trenches to the north had been improved and re-wired. The hurricane bombardment was fired from and an 18-pounder field gun was brought up to the front line on the left flank, to demolish of the German front line to make an obstacle.


2 March

The attackers were guided forward from and attacked on time at Two minutes later the artillery began a barrage behind the objectives and took the Germans by surprise, except on the left, where a German machine-gun crew cut down two platoons. The waves of infantry easily walked over the remaining wire unopposed. The German sentries at the Bluff were found under cover, expecting the artillery salvo after the usual two-minute pause and the rest of the garrison was in dug-outs in the western face of the large crater. To the north, the attackers overran the objective on the Bean, which they did not recognise, because the trenches had been obliterated. Parties which ventured further forward suffered many casualties and the survivors were pulled back to the objective where consolidation began. Later on, some Germans who had been bypassed opened fire but soon surrendered and were sent to the rear. On the left flank the British troops were reinforced and by had captured the machine-gun nest. The attackers took although them were only taken from the dug-outs at the Bluff after resisting into the evening. The raiders blew in the gallery in no man's land that led to the Bluff but those from the 172nd Tunnelling Company were killed by machine-gun fire. The German artillery reply began at but intense fire did not begin until by when the British had emptied their front line and made rapid progress in consolidation. The German artillery continued a high rate of fire until and severely damaged the old and new front lines, which took much work to repair. One of the trenches was named International Trench after dead from three armies were discovered. GR 123 had been exhausted by the 36-hour preparatory bombardment, which destroyed the German positions. In the evening bombers from GR 123 and parties from IR 124 and IR 127 counter-attacked. The British bombers, with plenty of Mills grenades and supported by many machine-guns were able to repulse the Germans. (Each attacker had carried two grenades and had been dumped close by.)

(25 September – 13 October) and the extension of the British front in early 1916, the BEF was at a tactical disadvantage against the German army, on wetter ground, easily observed from German positions. When the BEF took over more of the Western Front from the French, it was to be held lightly with outposts, while a better line was surveyed further back. The survey revealed that all of the French gains of 1915 would have to be abandoned, a proposal that the French rejected out of hand. For political reasons, giving up ground around Ypres in Belgium was also unacceptable, only an advance could be contemplated to improve the positions of the BEF. Since the French and British anticipated early advances in 1916, there seemed little point in working on defences, when the Germans were building more elaborate defences, except at Verdun. Rather than continue the informal truces that had developed between French and German trench garrisons, the British kept an active front and five of the German local attacks in the period were retaliation for three British set-piece attacks. In early 1916, the Germans had an advantage in trench warfare equipment, being equipped with more and better hand grenades, rifle grenades and trench mortars. It was easier for the Germans to transfer troops, artillery and ammunition along the Western Front than the Franco-British, who had incompatible weapons and ammunition. A substantial cadre of German pre-war trained officers NCOs and soldiers remained; the British wartime volunteers gained experience in minor tactics but success usually came from machine-guns and the accuracy and quantity of artillery support, not individual skill and bravery. In the underground war, the BEF tunnellers overtook their German counterparts in technological ability and ambition. With sufficient artillery, the capture of a small part of the opponents' line was possible but holding it depended on the response of the opponent. When the Bluff was captured, the British retaliated and retook it and Mount Sorrel and Tor Top were retaken by Canadian troops; when the British took ground at St Eloi and Vimy Ridge, the Germans took it back. The constant local fighting was costly but enabled the mass of inexperienced British troops to gain experience, yet had the front been less densely occupied, more troops could have trained and the wisdom of each school of thought was debated at the time and ever since.
