Lord Molyneux made his way south by 1645 and was given command of Prince Maurice’s Lifeguard of Horse, perhaps incorporating remnants of his own regiment.
According to Blount: The Lord Mollineux figured a Sun obscured by a Cressant, the word from the Sun was, QUID SI REPULSERO? from the Cressant (which darted its horns (as they call those of a new Moon) to obscure the Sun) VAE CORNBUS MEIS. By the Sun surely was meant the King, and by the corniferous Cressant the Earle of Essex1).
Lieutenant Colonel Caryll Molyneux's cornet featured a stag's head supported by five hands and the motto AD QUID EXALTATIS CORNU, translated as to what do you exalt this horn?. The motto alludes to the Earl of Essex's cuckolding and perhaps the Five Members. The colour of the flag was not recorded2).
Richard, Second Viscount Molyneux of Maryborough a Lancashire Catholic, his military biography is available online at Lord Molyneux's.
Caryll Molynuex was the younger brother of Lord Molyneux, succeeding him as Viscount in 1654.
