At the beginning of August 1916, three French and one British division with 45,000 men and 400 guns launched an offensive against the Bulgarian positions at Lake Dojran, defended by the 2nd Thracian Infantry Division.

All four attacks that followed on 10, 15, 16 and 18 August were repulsed by the Second Division, and the Allies were forced to retreat to their original positions with heavy casualties.

Other sources state that the French took Tortoise Hill (Tortue) and Doldzeli, an area of 30 km2, but at a very high cost.

[1][2] The British 7th Battalion of the Oxfordshire & Buckinghamshire Light Infantry took Horseshoe Hill.
