 The Greeks and the British were aiming to capture the Bulgarian positions in the hills above Dojran Lake.This was not the first time the Allies had attacked Dojran - in 1916, an Anglo-French attempt was repulsed by the Second Thracian Infantry Division; the British had twice failed to capture it in 1917.The fortifications were well built (by Bulgarian engineers), the Bulgarians having spent the first months of 1916 and early 1917 strengthening the positions.
