The German units of the XI Army who had escaped capture, withdrew into Serbia to join the other German and Austrian forces already there or on their way from other sectors. Thus the 21st Infantry Regiment, elements of the 256th Reserve Regiment (the one which had appeared recently on the Struma front), of the 275th Regiment, which was in Macedonia, and of the 12th Landwehr concentrated in Serbia. From France the Alpen Corps arrived, which had only just come out of the line after much hard fighting, the 50th Landwehr from Minsk, and from South Russia the 217th and 219th Infantry Divisions, while Austria sent the 9th Division withdrawn from Italy, and the 25th. But these troops did not all reach the new front at the same time, except those who were already in Serbia or who had retreated from Macedonia; the other reinforcements arrived par petits paquets. In Roumania there was a still more numerous Army—on paper—commanded by Marshal von Mackensen, consisting of 3 German divisions, strengthened by 7 Landwehr divisions from Russia. This force, echeloned along the Danube from the Iron Gates to Cernavoda and along the railway from Cernavoda to Constantza, was divided into two armies, one of which assumed the name of the XI German Army which had gone to pieces in Macedonia, and was commanded by General von Scholtz himself, and the other, called the Army of Occupation in Roumania, commanded by General Koch. These forces were, in appearance, by no means negligible, but were spread over too vast a front, and the difficulties of communications south of Belgrade rendered their concentration very slow. Many of the men, moreover, belonged to the older classes and were partially unfit.
Even for the Allies communications were now extremely difficult. As far as the line of the old front they were comparatively good. But beyond it the retreating enemy had destroyed the railways, and the roads were in an appalling condition. From Ghevgheli to Veles the line was destroyed in many places, but it was repaired fairly quickly, so that by October 15th trains were already running with one interruption. From Veles to Uskub the destruction had been almost complete, as was also the case north of Uskub. The Constantinople railway was interrupted at Demir Hissar, where the bridge, as we have seen, had been blown up by the French early in the war. The C.A.A. had therefore to limit the number of troops pushing north to an indispensable minimum. Nothing, however, could restrain the Serbs, irresistibly drawn forward by the longing to return to their homeland. For supplies they had to rely on lorries, and the British provided them with 300 Fords, carrying 500 kilograms each, for the roads over which heavier vehicles could not pass.
AFTER THE VICTORY. ENEMY PRISONERS.
To face p. 256.
The objectives of the Allies were now four: the liberation of Serbia, the occupation of Bulgaria, the liberation of Roumania, and the capture of Constantinople. The territory over which the Armée d’Orient was operating, already vast before the Bulgarian capitulation, had now become immense; it was, we may say, the whole of the Balkan Peninsula, except Albania, which was left to the Italian XVI Corps, and Eastern Thrace, still in Turkish hands. To the north its operations were intended to link up eventually with those of the Italian Army, and General Franchet d’Espérey said that he hoped soon to shake hands with General Diaz in Croatia.
The I Serbian Army, the Danube Division leading, undertook the first of these tasks, supported by the French and Serbian cavalry, while the II Army still remained for a little to mount guard on the Bulgarian western frontier. The left flank of the I Army in the Mitrovitza area was covered by the Tranié Group, which, however, was relieved between the 5th and the 20th of October by the II Serbian Army and moved eastward. On the 7th the I Army was at Leskovatz in Old Serbia[47] and advancing on Nish, which the Austro-Germans had orders to hold at all costs, as it was the chief centre of the area, with immense depots and dumps, and the junction of the Belgrade-Salonica railway with the line towards Sofia and Constantinople; a local line also branches off to Zayetchar. A force consisting of troops of 3 German divisions (217th, 219th and Alpen Corps) and of 2 Austrian divisions (9th and 25th) tried to hold back the Serbs. But the latter on the 11th had occupied the heights dominating the town from the south, thus obliging the enemy to evacuate it after a brief engagement. The I Army continued its advance along the Morava valley, preceded by the cavalry, and did not trouble to await the two forces that were to support its flanks—the II Army on the left and the French divisions of the A.F.O. on the right, which had been delayed by the state of the roads—but was content with the support afforded by the Serbian and French cavalry. The enemy offered some resistance at Bukovich, and then at Parachin, where the fighting was more obstinate (October 23rd-24th); but the Serbs, although inferior in numbers, inflicted a serious defeat on them. This obliged them to evacuate even their positions at Kraguyevatz to the west of the railway, with its important arsenal. This town was occupied by the Drina Division on the 26th, which the following day conquered Mounts Ovchar and Chablatz, dominating positions and the scene of Voivod Michich’s great victory in the winter of 1914. On the 30th the I Army reached the Danube, and occupied the Biskuplje-Semendria line, while other detachments, after a sharp struggle, captured Mount Kosmaj and then Stoinik, 38 km. from Belgrade, whose outer defences are dominated from that point. On November 1st the Serbs re-entered their capital in triumph.
In the meanwhile the II Army was advancing through the Sanjak of Novibazar and Western Serbia, while the Tranié Group was pushing on towards Montenegro and Bosnia. On October 7th it had reached Ferizovich, on the 12th, after a sharp fight, Mitrovitza, and on the 15th, Ipek (Montenegro), where it captured 600 prisoners; 900 more fell into its hands on the 20th, after which it effected a conversion to the east, leaving the Yugoslav Division in charge of that area. The only French detachment remaining there was the 58th Battalion of Chasseurs à pied, while the 57th Division returned to Macedonia to be broken up.
The II Group of Divisions (General Patey), comprising the 17th Colonial and the 76th Divisions, to which the Tranié Group was now also attached, extended its occupation to Western Serbia and Eastern Bulgaria, which it entered by rail. On the 17th it was at Pirot, whence it pushed on an advanced force to Kniazhevatz, and on the 19th it reached Zayetchar. The 76th Division reached the Danube, and occupied the loop of the river between Vidin and Lom Palanka, thus interrupting the navigation on the Danube for the Central Empires. General Jouinot-Gambetta’s cavalry group had already reached the river, after a fantastic raid from Uskub. On the 27th it occupied Mount Antonov-Kladenatz, beyond Zayetchar, and then Dolnji Milanovatz near the Danube. On the 30th it was north-west of Negotin and in liaison with the Serbian cavalry, followed at a short distance by the 17th Colonial Division.
By November 1st the whole of Serbia was free of the enemy, except the north-west territory; but out of this, too, they were soon driven by the II Serbian Army, which then spread over into Bosnia and Montenegro. The remnants of the German and Austrian Divisions, exhausted and without supplies, recrossed the Danube and the Save. The whole of Bosnia arose in favour of the Yugoslav State, and also in Croatia and Slavonia there were demonstrations in the same sense. In the Banat, which the Serbs entered after crossing the Danube at Moldova and Basiatz, some final engagements occurred with the German troops, who were invariably defeated.
