In August 1643, Lord Grey was replaced as commander by the Earl of Manchester. Oliver Cromwell was appointed Lieutenant General of the Horse. The two men clashed, especially over Cromwell's selection of officers. Manchester wrote, "Colonel Cromwell raising of his regiment makes choice of his officers not such as were soldiers or men of estate, but such as were common men, poor and of mean parentage, only he would give them the title of godly, precious men..." Late in 1643, Lawrence Crawford was appointed Sergeant-Major General of the Foot. He too frequently clashed with Cromwell.
