Later Colonel Thomas Tyrell’s, then Colonel Richard Ingoldsby's Regiment of Foot
Parliamentarian regiment of foot raised by John Hampden that served with the Earl of Essex’s army
Under Hampden the regiment wore green coats with yellow linings, receiving them as early as August 23rd, 1642 1). Note. Although the warrent for the issue of uniform is indeed dated 23/08/42 This is not the date the clothing was issued to the regiment. Two days after the warrant Hampden's agent in London received 1000 each of shirts, pairs of shoes and snapsacks, the coats were not received at this date and followed in at least three seperate batches. 460, possibly in two issues of 400 and 60, were received at an unknown date, 400 were received on 06/09/42 and the final 140 3 days later. The last 2 batches at least were delivered to William Smith a London carrier to be transported to the regiment. From this it would appear that the regiment would not have received it uniform until mid-September at the eariest.2) They seem to have kept this coat colour in the 1643 reissue. A pay warrent of 7th Dec 1643 refers to “Colonell Thomas Terill Colonell of ye green Regimt late of Colonell Hampden” 3), although this might refer to the colour of their flags.
Although many publications suggest that they carried a green flag with a motto VESTIGIA NULLA RETRORSUM this appears to instead have been a cornet from Hampden's troop of horse and Hampden's foot colours remain unknown, unless the reference to 'ye green Regimt' refer to flag colour which appears possible. However a damaged bill addressed to John Hampden, includes the item “It for ten collers of r[ torn ]”(SP28/328/507). In November 1644, with the re-equipping of Essex's foot, they were issued either green colours (with differences of yellow billets, yellow half moons or white diamonds), or crimson colours (with differences of yellow mullets or white balls) 4).
Thomas Tyrell also commanded a regiment in Aylesbury garrison Col. Thomas Tyrell's Regiment of Foot
Hampden's Regiment are re-enacted by Colonell John Hampden's Regiment of Foot of the English Civil War Society and by Colonel John Hampden's First Captain's Company of the English Civil War Society of America.
