He held the rank of Colonel and commanded a regiment of Horse, i.e. cavalry.

He took his brigade of 2,500 mounted troops of the New Model Army which was detached to join the Scots Covenanter Army following a polarised debate in the Committee of Both Kingdoms.

On 8 June 1645 Vermuyden met with Oliver Cromwell to explain that pressing matters overseas meant that he would have give up his commission in the New Model Army. Cromwell agreed to discharge him. When the House of Commons agreed to Fairfax's request that leave should be given for Cromwell to lead the Cavalry in the New Model Army, he assumed personal command of Vermuyden's troops.
