Lambert commanded the cavalry left in Hull during the Second Siege of 1643 while Sir Thomas Fairfax led the main body of Northern Association horse to reinforce Manchester.

Lambert was given command of Montagu's New Model Army Foot in October 1645, while his cavalry regiment remained with Poyntz's Army of the Northern Association. Exactly what happened to the regiment next is uncertain, it may have been taken over by another colonel, perhaps Poyntz himself. In July 1647 Lambert returned to Yorkshire and superseded Poyntz as General of the Northern Association, taking over one of the regiments of horse, likely Poyntz's but perhaps another, as Colonel John Lambert’s Regiment of Horse.


According to Blount: Col. Lamberts devise of Yorkshire, may seem to speak no ill to Monarchy, where was figured a regall Crown set on the top of a Pillar, and a hand out of a cloud holding it on, with this motto, UT SERVAT INCOLUMEN2).

Illustration 1 shows another design for Lambert's cornet, blue and red with the motto PRO REGE ET VERITATE “For King and truth”.
