Regiment of English horse serving in Ireland under Inchiquin

Service History


  • June: Regiment commissioned
  • July: Two further troops added to regiment


  • August: Serving under Inchiquin in Munster


Sidney was commissioned in June 1646 to raise a regiment. It was intended to be based on five troops from the Eastern Association under Major Le Hunt, Major Gibbs (as a capt), and Capts Holcroft, Pell and Chopham (Choppine or Chopping) which had already agreed to serve in Ireland. In the event the men proved mutinous and only Chopham appears to have served in the unit, and he apparently did so with a newly raised troop rather than his old Eastern Association one.1)

Flags and Equipment

Colonel Algernon Sidney's cornet in the Eastern Association was blue with a yellow motto SANCTVS AMOR PATRIAE DAT ANIMUS2)3). It is unknown whether he used the same design in Ireland.
