The Earl of Northampton's Regiment of Horse

The Earl of Northampton raised this unit of Horse in 1642, and it served with the Oxford army until 1646. One source says the regiment wore green coats, so I went with that.

The Colonel, the 2nd Earl of Northampton, was killed in action at Hopton Heath in 1643, the title and the regiment then passing to his son .

The exceeding useful British Civil War Regimental wiki  says the unit had blue coronets with blue and white fringes, but I liked this flag better, with the green field complementing the coats.

The motto on the flag is an insult to the Parliamentarian commander, the Earl of Essex, "whose wife was notoriously unfaithful".

My color printer remaining uncooperative, I printed out the flag in black and white and then painted over the design. The flag is from the Dux Humunculorum blog; there quite a few more ECW flags on his blog.  (Somehow the inscription makes me think of a political figure and his alleged pastimes in Moscow, but we'll leave it at that!).
