turning the left flank of the Bulgar-Germanic army forced it back to the lines at Kenali beyond the Greek frontier. These had been selected by Mackensen and strongly fortified, and a frontal attack by the French and Russians on 14 October broke down (see Map, p. 151). Better success attended the Serbian efforts to turn the enemy flank. By 5 October they had secured the crossing of the Tcherna at Brod, and slowly they pushed across it. Bad weather delayed them for a month, but by 15 November Mishitch had mastered the river bend from Iven to Bukri; and, thus outflanked on their left, the enemy yielded to the Franco-Russian attacks on Kenali and retreated to the Bistritza, four miles from Monastir. On the 16th and 17th the Serbians again attacked on the mountains in the Tcherna bend, carried the Bulgar positions, and by the 19th had reached Dobromir and Makovo whence they threatened the line of retreat from Monastir to Prilep. On that day the Germans and Bulgars moved out of and the Allies into Monastir. Their position was further improved before the end of the year, and it is said that had Mishitch been allowed the use of reserves, Prilep would also have fallen and Monastir been spared the annoying bombardment which it suffered at intervals for nearly two years. For its capture marked the limit of Entente success in that sphere until the closing months of the war. The campaign had not been fruitless, for Greece had been saved as a brand from the burning, and presently did her part in the Allied cause. But the Balkan corridor had been expanded by the Rumanian disaster into a solid block, and revolution in Russia soon put an end to all threats from the north. The hopes that were built on Salonika were destined to remain in abeyance until events in September 1918 justified the faith of those who refused to abandon the Balkans.
