Early 1855 he was posted in the Yevpatoria Garrison in Crimea commanding a 400-strong cavalry regiment. His unit made a critical contribution in successfully repulsing a strong Russian assault on the town, which was threatening the rear of the Allied army besieging Sebastopol (see:Battle of Eupatoria) This victory brought him a second promotion in a year, making him a Pasha (general), (specifically a Mirliva, equivalent of a brigadier general).
