The disastrous retreat through Albania in which the Serbian Army had lost nearly all its artillery and more than half its effectives, took refuge in Corfu, save a few detachments which were sent to Bizerta. In Corfu the exhausted and worn-out soldiers rested, were re-equipped with everything and thoroughly reorganized. As soon as they began to recover from their terrible experiences they wished to go to Macedonia to take part in the Allied operations. They began to reach Salonica in the spring of 1916, and at the end of April there were about 15,000 of them, besides the detachment formed of the men who had escaped from Monastir. At the end of June they amounted to 120,000 and in July to 152,000. They were divided into three armies, each comprising two divisions: I Army (Morava and Vardar Division); II (Shumadia and Timok) and III (Drina and Danube), in addition to the cavalry division and the volunteer corps, with 72 machine-gun sections. The artillery was supplied to a great extent by the French, except for a few guns saved in the retreat, to which some others captured from the enemy were afterwards added. They had 6 groups of 75 mm., 6 of 80 mm. mountain batteries (afterwards replaced by 65 mm. quick-firing guns), 6 groups of Krupp 70 mm. or Schneider 75 mm. mountain guns, 6 groups of 120 mm. howitzers, 6 batteries of 58 mm. trench guns. Scattered about the mountains along the border between Macedonia and Albania and in Macedonia there were irregular Serbian comitadji bands estimated, in July 1916, at about 5,000 men, who broke up and reformed according to circumstances, now attempting a raid, now hiding among the mountains. Other bands continued to exist in Old Serbia, and in fact they rose in revolt in the winter of 1916–17, causing serious anxiety to the enemy; the movement, however, was ruthlessly repressed.
