The scenario was set quite soon after the battle of the Alma, while the Allied forces were setting up their bases on the southern shores of the peninsula and establishing siege lines in front of Sevastopol. In an attempt to drive the Allies back on their bases, or at least to delay the establishment of siege lines until more Russian forces could arrive, the Russian commander attacked across MacKenzie Heights.
The Russians easily secured their primary objective, the MacKenzie farm that covered the heights, but success of the operation could only really be assured by the occupation of the hill south of the farm that dominates the road between the British and French supply lines.

One brigade of eight battalions to their right and another brigade of eight battalions to their left. This brigade has massed their guns into a grand battery opposite the French. The British are entering the field in the top left and French are entering on the bottom left. The Russian commanders decided to concentrate against the French. The cavalry, four battalions of infantry and one battery would hold the British. On the Allied side there was no coordination but just a hardy handshake and a cheerful good luck.
