The Macedonian Campaign has been largely ignored by history.
In September under his dynamic command French and Serbian forces finally punched their way through the Bulgarian lines in the center of the Moglena mountains, and, supported by a Franco-Italian force on their left and a British-Greek force o.
Then in 1918 a key leadership change was made with the appointment of General Franchet d\'Espèrey.
The British fought successful actions in the Struma valley but suffered costly reverses against the virtually impregnable Bulgarian defenses west of Lake Doiran on two occasions.
The Serbians consolidated a strong position to the west of the Moglena mountain range, and with the French advanced into Serbia as far as Monastir.
While the first two of these objectives were met, territorial gains in 1916 and 1917 were limited.
Apart from tying down a substantial Germano-Bulgarian army, the Allied army\'s objectives were to prevent the Central Powers from breaking into Greece, to bring Greece and its army into the Allied camp, and, above all, to prepare for actions and advances into Bulgaria and enemy-held Serbia from the south.
By the end of 1916 the Allied Army of the East, with contingents also from Italy and Russia, had expanded into 20 divisions.
Reconstituted into six divisions it was subsequently shipped to Salonica to form part of an Allied force of 15 divisions under the command of General Maurice Sarrail.
It was too late, but a large part of the Serbian Army escaped to the Adriatic.
The Campaign had its origins in October 1915 when a small Franco-British force disembarked at Salonica, with orders to advance into Serbia to aid the beleaguered Serbs.
But in the end the Allied Army of the East met its defensive objectives and vastly exceeded its offensive ones.
The ambivalent position of Greece, the Romanian misadventure, the intricacy of Balkan politics, the depredations of malaria, and inter-allied tensions both in Macedonia and at Allied government level all added further layers of complexity.
The terrain fought over, from marshy river valleys to 2,000 meter mountain ranges, presented special military challenges.
Almost accidental in its origins the reality of a six-nation Allied army gradually took shape.
The annals of the First World War hold few events to compare with the triumphant final offensive of the Allied Army of the East, and the whole story of the Campaign is rich, diverse, and relevant.
Such neglect is misplaced.
