The Battle of Transylvania also caused the replacement of the Chief of Staff of the German Army and the shifting of German attention to the region, causing German offensive operations at Verdun to cease.

The 3rd Army, numbering 72,000 soldiers, was tasked with holding off a potential Bulgarian attack. Hypothesis Z envisioned an Austro-Hungarian opposing force numbering 70,000, but in reality, the actual number was less than half of the Romanian estimate. Another inaccurate Romanian estimate was the number of reinforcements that the Central Powers could deploy to the region: 100,000 compared to the actual number of 300,000. In July 1916, the Austro-Hungarians began preparations for an eventual defense of Transylvania. By early August, enough units had been gathered in order to form an army, the 1st. On 7 August, this new army was put under the command of General

Battle


South-Western Front

The Romanian 1st Army, commanded by General Ioan Culcer, crossed the border at the Surduc and Vulcan Passes and occupied Petrozsény (

). Although Muica waited for the rest of his Corps as planned (2nd Division and 1st Cavalry Brigade), this allowed the Austrians time to regroup. Sixty-five miles to the East, Culcer's main force - the Olt-Lotru Group - entered the Red Tower Pass and advanced towards Nagyszeben (

. Castris accepted the surrender, and neither side occupied the city, as the Romanians made no effort to occupy it and the Austrians withdrew. The 1st Army advanced very little throughout September. Its Eastern flank continued to dig in just south of the city, reinforcing its defense lines, while its Western flank moved into the Merisor (Merișor) valley. It inched northwest along the valley, but never left it. The Romanian forces stopped upon running into Austrian and German defenders, coupled with the threat of German forces disembarking at Karánsebes (Caransebeș). By mid-September, the German 9th Army, under the overall command of Field Marshal Erich von Falkenhayn, was deployed to the region. However, the first German unit to arrive in Transylvania was the 187th Infantry Division, under Major General Edwin Sunkel. Its 187th Regiment was deployed to the area on 5 September. The Germans and Austrians began advancing on 14 September, and on the 18th they took Petrozsény (

). On 23 September, a skirmish between Germans and Romanians resulted in 107 Germans killed or wounded and 100 Romanians killed plus 23 more captured. The Battle of Nagyszeben (Sibiu) began at the dawn of 26 September, with an attack by the German 9th Army. Its forces in the area were commanded by General

, and included the Hungarian 51st Honvéd alongside two German units (187th Division and 76th Reserve Division). The German plan was to isolate the Romanians and cut off the escape route through the Red Tower Pass. The German attack on the 26th ran into stiff resistance, and failed. After amassing his artillery, von Staabs attacked again on the 27th, driving the Romanians towards the mouth of the Red Tower pass by nightfall. Twenty-four hours later, von Staabs had pushed the Romanians into the Pass. German Alpine Corps were deployed to both ends of the Pass on the 26th. The Romanian 48th Infantry Regiment was decimated by German machine gun fire when deployed against the German positions at the North of the Pass. Subsequently, Romanian forces in the Pass moved to its Eastern side, out of the range of German machine guns. Lacking heavy field artillery, the Germans could not completely block the Pass. The Romanians managed to drive off the Germans from the North of the pass, and temporarily from the South of it, but the latter soon returned. The Romanians began their retreat through the pass in earnest on the 28th, through the bullets of the Alpine Corps and German barricades of dead horses and wagons, which had to be blasted away by artillery. In the final hour of the battle, the Romanians made their way through machine gun fire towards the buildings which served as the firing points for the Alpine Corps at the South of the Pass, and bayoneted to death everyone inside. Then, during the afternoon of the 29th, the Romanian forces made it out of the pass and reached safety. Despite the heroic efforts of the Alpine Corps, the bulk of the Romanian force had escaped. The Germans captured the relatively small number of 3,000 prisoners. Although the bulk of the Romanian 1st Army had retreated from Transylvania, more fighting was yet to come. After the Germans captured Petrozsény (

), they shifted four of their six battalions in the city to contribute to the Battle of Nagyszeben (Sibiu). Ethnic Romanian sympathizers living in the region made General Culcer aware of this, and thus the Romanians counterattacked and re-captured Petrozsény (

) on the 25th of September. In response, Falkenhayn deployed the German 301st Division under General Johannes von Busse, which arrived in the region on the 28th, linking up with the 2nd Austro-Hungarian Mountain Brigade. The Central Powers commenced their attack on the 30th, capturing Petrozsény (

) and the Surduc Pass by 5 October after hard fighting. This time however, the Romanians succeeded in destroying the vital coal mines before retreating.


South-Eastern Front

The Romanian 2nd Army, commanded by General Alexandru Averescu, converged on Brassó (Brașov) through five mountain passes. It was opposed by the 71st Infantry Troop division, commanded by General Anton Goldbach. At the Alsótömös (Timișu de Jos), the Székelys' 1st Battalion, supported by an armored train, held its ground for an entire day, only being pushed back on the night of 28 August. In the afternoon of the 29th, the Romanians closed on Brassó (Brașov), their artillery destroying the last train. After local ethnic Romanians surrendered the city to the commander of the 6th Infantry Regiment, Romanian units entered Brassó (Brașov) at around 5 pm and paraded towards the municipal plaza. At the start of September, the 3rd Division inched west along the Olt river towards

(Făgăraș) to Homoród (Homorod), threatening the juncture between two German units. A breakthrough there would have, at the very least, prevented the German 9th Army from advancing on Nagyszeben (Sibiu). However, the 2nd Army's new commander, General Grigore C. Crăiniceanu, was unaware of just how close he was to rupturing the enemy lines and smash open the front. A Central Powers counterattack stopped the plodding Romanian forces. Crăiniceanu's timidity stemmed partly from the fact that the Romanian General Staff had recently stripped his army of half of its strength, shifting three of its divisions to the

front. The 2nd Army began to advance northwest again after 10 days. The town of Fogaras (Făgăraș) was taken by the 2nd Army on 16 September. The 2nd Army started advancing again on 29 September, pushing back the Honvéd 2nd Cavalry Division and reaching Székelykeresztúr (

), a dozen miles from Segesvár ( Sighisoara). The initial German advance in the region was resisted by a powerful Romanian counterattack, which inflicted heavy German losses. However, instead of pressing their advantage, the Romanians began to withdraw to their defensive line West of Brassó. After a mostly unhindered retreat, made possible by the Romanian counterattack at the start of October, the Romanians took up defensive positions to the West of Burzenland late on 4 October, fighting in the area starting early on 5 October. The town of Fogaras was held by the Romanians between 16 September and 4 October. The Battle of Brassó (Brașov) lasted from 7 to 9 October. There was a thick fog on the night of 7 October, however this did not prevent two regiments commanded by Sunkel from entering the outskirts of the city earlier that day. When the fog cleared on the morning of the 8th, it revealed walls of Romanian infantry standing between Sunkel's regiments in Brassó (Brașov) and the 187th Regiment outside the city. Although initially dissolved by artillery fire, the Romanian formations soon reformed and advanced amidst German artillery shells. Romanian riflemen moved towards Barcaszentpéter (

), but most were forced to withdraw by German machine gun fire. Although a few Romanians found cover in the corn fields, most retreated to their initial positions. The Romanians in the corn fields could not be dislodged, despite repeated attempts. Inside Brassó (Brașov), house-to-house battles raged in the outlying sections of the city. Powerful Romanian counterattacks against Sunkel's two regiments repeatedly failed. A Honvéd brigade led by a Colonel Gundell accompanied the Germans, and together they slowly scattered several Romanian battalions. At around 3 pm, the German 89th Division attacked the Romanian forces around Barcaszentpéter (Sânpetru), but for some inexplicable reason the Germans failed to press all the way to the village. Destroyed bridges, poor reconnaissance and minor enemy resistance ultimately stopped the tired soldiers of the 89th Division, which set up camp near the village despite Falkenhayn's orders to "stay glued to the retreating enemy". The Romanians retreated from Brassó (Brașov) during the night of 8/9 October, amidst German machine gun fire from vantage points in and around the city. Many trains, loaded with artillery, munitions, supplies and even soldiers, were abandoned. The 187th Infantry Regiment marched into town on the morning of 9 October, as soon as it was daylight, amidst cheers of the local Saxon population. An entire Romanian company was found dead near the train station, mowed down by German machine guns. Added to these were 1,175 prisoners. Twenty-five artillery pieces and numerous small arms were also captured.

Opposed to the North Army was the Austro-Hungarian 61st Infantry Troop Division, which included two Honvéd reserve brigades (the 16th and the 19th). The two brigades had recently returned from the Galician Front, and were in a state of collapse. The weak Austro-Hungarian forces fell apart at the first push of the Romanian covering forces.

A setback for the 2nd Army came during the Battle of the Kelemen (Călimani) Mountains. During fighting which lasted from 17 September to 9 October, the Austro-Hungarian VII Battalion of the 73rd Infantry Regiment (reinforced by the 6/9 Mountain Artillery Battery) under the command of Colonel Sámuel Sándor, together with gendarmes under the command of Major Ziegler, drove the Romanians back to the East of the mountains. Austro-Hungarian casualties totaled 199 (10 killed, 63 wounded, 82 missing and 44 captured) and Romanian casualties totaled 191 (136 killed and 55 captured).

The Romanian 15th Brigade of the 8th Division of the Romanian North Army took Kézdivásárhely (Târgu Secuiesc) on 29 August. Austrian military maps reveal that the town remained in Romanian hands well into October. On 8 and 9 October, as the Battle of Brassó was drawing to a close, two Romanian units retreated from the north and northwest and formed a defensive perimeter around Kézdivásárhely. As of 14 October, most of the Romanian North Army's positions had fallen back towards the Romanian border, with the exception of Kézdivásárhely. As late as that day, the town was still firmly in Romanian hands, with Romanian positions to both the north and the south of it. It is not known when exactly was the town retaken by the Central Powers, but the date could only be 15 or 16 October, because on the latter date, the Battle of Transylvania ended: by 16 October, the Romanians had been driven back all along the line and Transylvania had been cleared.


Romanian occupation of Transylvania

The Romanian occupation of Transylvania was geographically divided into two territories. The larger territory comprised the area occupied by the 2nd and 4th Armies. These two armies managed to come into touch and form a contiguous front. The smaller territory comprised the area occupied by the Romanian 1st Army. A gap of 15 miles separated its extreme right wing from the vanguard of the 2nd Army. Although the location of the 1st Army's extreme right wing was later reached by the 2nd Army, the Romanian detachment which had stood there had been forced to retreat, and the two armies remained separated. At peak, the three Romanian armies were in control of almost a quarter of Transylvania's historical territory (~14,000 square km).

The zenith of Romanian rule in Eastern Transylvania during 1916 lasted just under two weeks. For 13 days (21 September to 4 October), the Romanian 2nd and North Armies occupied five Hungarian county capitals. Brassó (

Aftermath

The Romanian invasion caused the sacking of Erich von Falkenhayn as the Chief of Staff of the Imperial German Army. He was replaced by

. Falkehnayn's dismissal made him "the first German casualty of the campaign". Stopping the Romanian advance into Transylvania became the top German priority, meaning that the offensive at Verdun had to be ended. The German 9th Army was created on 6 September specifically to deal with the situation in Transylvania, and it was commanded by Falkenhayn. Several of its units were moved to Transylvania from various fronts: two Reserve Corps headquarters from the Baltic Front, the 187th Infantry Division from

, the 89th Infantry Division from Galicia, and the 3rd Cavalry Division from Russia. Although commanders from all fronts begged Ludendorff for reinforcements, the latter made his priorities clear: "Hold on to all our positions along the Western, Eastern, Italian and Macedonian Fronts; nddeploy any and all available forces for the decisive blow against the Romanians.". The Austrians moved mountain brigades from the Italian Front to Transylvania, while the Germans redeployed the Alpine Corps from Verdun and the 76th Reserve Division from

. Before the counter-offensive of the Central Powers, it was established that Germany would be in charge. On 28 August, the Austrians - unable to muster resistance at any level - reluctantly agreed to a unified Central Powers command for the Eastern Front. This essentially meant handing control of all military operations to the Germans. Due to the Austro-Hungarians being initially outnumbered more than 10 to 1, Romania could be defeated only through the joint effort of all four Central Powers, but this would have been possible only under a unified command. During September the Central Powers ratified agreements making the German emperor their supreme commander, a concession which gave Hindenburg and Ludendorff control over the Austro-Hungarian, Bulgarian and Ottoman armies. Politically, the new unified command under the German Kaiser was created on 7 September. It not only cemented German ascendancy in the Berlin-Vienna alliance, but also limited the Austro-Hungarian diplomatic initiative. The Central Powers chain of command during the battle was clear: the Austro-Hungarian General Arz was the one taking orders from the German General Falkenhayn, not the other way around. An example of this can be found towards the end of the battle, when Falkenhayn ordered Arz to pursue the retreating enemy. The German 9th Army defeated and drove back across the Transylvanian border two Romanian armies, but failed to destroy them. The bulk of the Romanian 1st Army managed to escape through the Red Tower Pass, leaving behind only 3,000 prisoners. The Romanian 2nd Army left behind even fewer prisoners during its retreat across the border, just 1,175. The German 89th Division failed to "stay glued to the retreating enemy", as Falkenhayn had ordered. Instead, its tired soldiers set up camp. The amount of Romanian prisoners was small compared to comparable battles against the Russians. Falkenhayn attributed this to the ability of the Romanians to fade away into the mountains, but the speed of the Romanian withdrawal also played a part. Other factors for the "disappointing" number of prisoners include determined Romanian counterattacks which - combined with the ruggedness of the terrain - left the Germans too tired to conduct immediate pursuits, as well as determined rearguard actions which forced Falkenhayn's units to exercise caution. Nonetheless, the Germans did their absolute best, with Falkenhayn himself stating: "with the best will in the world it was not possible to increase our efforts". The Austro-Hungarian 1st Army performed much poorer than its German ally. Despite stubborn resistance, it continued to be pushed back by the Romanian North Army as late as October. When the North Army was ordered to retreat in early October, the exhausted Austrians moved slowly and gave their enemies an uncontested run to the border. The field performance of the opposing Romanian and Austro-Hungarian armies thus appears to confirm Ludendorff's statement: "The Romanians are bad soldiers; the Austrians even worse." Over 200,000 Hungarians and Saxons evacuated the border regions. Two thirds of the population of Nagyszeben (

During the Romanian offensive, the Austro-Hungarian ''Motorkanonwagen'' was destroyed by Romanian artillery. This was an armored self-propelled rail car, armed with a turreted 7 cm gun. It was the sole example made, and the most futuristic-looking piece of Austro-Hungarian rail armor.

and Brassó counties on the border with Romania. These counties welcomed the Romanian troops when they invaded, so they were united in this "cultural area" in order to prevent them from any exposure to "foreign influence". By the end of the war, over 3,000 Romanian primary schools were closed. Although the battle was practically over by mid-October, major operations in the region ceasing, this was not the absolute end of the Romanian occupation. For instance, when the Central Powers launched the

on 23 October, the Eastern flank of the Central Powers troops was several miles behind the Transylvanian border, meaning that the Romanians had held onto that sliver of Transylvanian territory up until that point. Although the battle was a Romanian victory, it did amount to a complete withdrawal of the Romanian 1st Army from Transylvania. A cause for confusion regarding the end date of the Battle of Transylvania lays in the fact that the region's borders had been altered since 1916. The town of

Analysis

When the battle started on 27 August, 34,000 Austro-Hungarian soldiers opposed 369,000 Romanians, amounting to a Romanian numerical superiority of over 10 to 1. This situation was largely reversed by the middle of September. By 18 September, the armies of the Central Powers amounted to more than 200,000 men, outnumbering the 10 Romanian divisions left in Transylvania. The Romanian offensive was doomed from the start. Its plan of action was the brainchild of General Vasile Zottu, who was paid by the Central Powers. Zottu's name was found on a list of people, , who were allegedly bought by the head of a major German oil company operating in Romania. Zottu was allowed the face-saving cover of taking sick leave. Zottu's campaign plan provided advantages for the Central Powers. The plan envisioned 12 days of regrouping after the initial Romanian crossing of the Carpathians. The Romanians halted their offensive at the end of August and started to dig in, pleasantly surprising the Germans and Austrians, who could "scarcely believe their luck". However, Zottu's plan was overruled at a war council on 2 September, and the Romanian offensive resumed. Zottu's plan also left the Romanian 3rd Army alone to defend the Southern border against Bulgaria. At Turtucaia, Romanian defenses consisted mainly of reservists with little or no military training and militias. This force also had only 72 working artillery pieces, and no bridge over the Danube. Finally, when German forces crossed the Danube at

in November, Zottu - with 60,000 troops under his command - did nothing but wait. After some discussions at a war council in Bucharest, Zottu confessed and was allowed to commit suicide.T.G. Otte, Routledge, Apr 15, 2016, ''An Historian in Peace and War: The Diaries of Harold Temperley'', pp. 88-89 The main drawbacks of the Romanian Army were its technological backwardness and lack of experience. It preferred frontal attacks by masses of infantry, but its forces wilted before machine guns and heavy artillery. Thirteen of Romania's 23 divisions had no howitzers at all, relying on light field guns of 75 mm and 53 mm. The 25 batteries of 120 mm howitzers were scattered among 10 lucky divisions. The 10 divisions also had on average 30 machine guns each, while each of the remaining 13 had half as many. By contrast, a German division in 1916 had on average 54 machine guns, not counting the light machine guns of its light infantry. The causes of military failure differed between the three Romanian armies. The 1st Army was simply overpowered. It successfully resisted the Germans at Nagyszeben (

) on 18 September, it counterattacked a week later on the 25th and briefly recaptured the town, enabling its troops to destroy its strategically important coal mines, before being pushed back for good between 30 September and 5 October. The 2nd Army had its commander replaced in early September and its forces halved, after three of its divisions were shifted to the Dobruja front. The new commander missed the opportunity to smash open the front in mid-September. The new commander of the 2nd Army, General Grigore C. Crăiniceanu, was poorly regarded. An officer of the general staff found him unqualified, while

, the leader of the Conservative Party, had this to say about his appointment: "How is that possible?...Do not make such a mistake; he has been confused all his life, and he is absolutely worn out.". Thus, while the Germans had defeated the halved and poorly-led 2nd Army by mid-October, it's not known if the outcome would have been the same if they had faced a full-sized 2nd Army under Averescu's command. Averescu, the 2nd Army's initial commander, would eventually be promoted to the rank of Marshal. The North Army, aside from a setback in the Kelemen Mountains, was not actually defeated. It continued advancing as late as October, despite stubborn Austro-Hungarian resistance. The North Army wasn't pushed back by the enemy, rather, it was ordered to retreat because of the events unfolding in Dobruja. Ordered to pursue the Romanians, the exhausted Austrians moved slowly, giving their enemies an uncontested run to the border. There, the Romanians settled into the defensive positions they had prepared before the war.
