Sunday, September 15, 1918

"On September 15, agreeably with the general forward movement of the Allies on all the fronts, the so-called Salonika Army developed an offensive against Bulgaria, having for its central objective the important town and railway junction of Uskub. It was indeed a heterogeneous army that advanced under the orders of Franchet d'Esperey, the ultimate successor of Sarrail. Eight French, seven British, six Greek (Venizelist), six Serbian, and four Italian Divisions—all under strength, wasted with fever, and modestly equipped with artillery, set themselves in motion against the mountainous frontiers of Bulgaria. Seventeen Bulgarian and two Turkish divisions, gripped and guided by a few German battalions and batteries and the prestige of Mackensen, constituted a force ample for a successful defence of such difficult country. But the Bulgarians would fight no more."

Quotation Context

Summary from Winston Churchill's history of the war on the Allied Balkan offensive that French General Franchet d'Esperey opened on September 15, 1918. General Maurice Sarrail had originally led Allied forces in the region, forces that had been invited by Greek Prime Minister Eleftherios Venizelos but opposed by Greek King Constantine. With French and British firepower backing him, Venizelos won and the King was deposed. German Field Marshal August Mackensen had been victorious on the Russian Front and in the conquests of Serbia and Romania. Bulgaria was war weary. By September, 1918 German forces on the Western Front had been driven back from all the territory taken in their spring and summer offensives.
