Throughout the winter of 1854–55 he remained in command of the division, and on 5 July 1855 he received the reward of his constancy by being made a Knight Commander of the Order of the Bath. Codrington arranged with General Edwin Markham, commanding the 2nd Division, the attack on the Redan of 8 September, but blame seems to have been showered more freely on Sir James Simpson, who commanded in chief since Lord Raglan's death, than on the actual contrivers of that fatal attack. On 11 November 1855, for some reason that has never been properly explained, Codrington succeeded Sir James Simpson as Commander-in-Chief instead of Sir Colin Campbell, who had much better claims to the succession, and he commanded the force occupying Sebastopol, for there was no more fighting, until the final evacuation of the Crimea on 12 July 1856.
