Later Colonel Isaac Ewer’s then Colonel Richard Lawrence’s Regiment of Foot
New Model Army regiment of foot, serving in the First and Second Civil Wars, on Cromwell’s Irish campaign then in Ireland up until the Restoration
A history of the regiment is given in The Regimental History of Cromwell's Army by Sir Charles Firth and Godfrey Davies, Clarendon Press, Oxford, 1940.
There is an online history by Hammond’s re-enactment group of the Sealed Knot Hammond’s.
The regiment was formed from Crawford’s Regiment of Foot and probably Hobart’s regiment of foot, both from Manchester’s army. Originally the Colonelcy was offered to Crawford, but he declined and returned to Scotland. Victorious at Naseby, they went on to fight in the Western campaign and were detached under Cromwell for a number of sieges.
Hammond was appointed governor of the Isle of Wight so the regiment passed to its Lt Col, Isaac Ewer. At the start of the Second Civil War the regiment were with Cromwell, marching on South Wales. Cromwell left Ewer to besiege Chepstow Castle while he marched west to Pembroke. After storming Chepstow Castle they headed east to the siege of Colchester, under the command of Fairfax.
In 1649 the regiment accompanied Cromwell on his Irish Campaign, fighting at the notorious siege of Drogheda in 1649, then in a number of sieges throughout 1650. Ewer died over the winter of 1650-1 and was eventually replaced by Colonel Richard Lawrence. Lawrence’s regiment served in Ireland up until the Restoration, when they were probably disbanded.
Red coats. On the 23rd of April 1645 Crawford’s regiment were provided with funds to buy 10 new colours. This is the regiment that became Hammond’s when Crawford declined to serve in the New Model Army. Neither the colour of the flags nor their design is known. In June 1649 Ewer's regiment were allocated £20 for new colours.
