 He was a Knight and he was recorded as being Lord Lieutenant of Buckinghamshire on two separate occasions, in both 1569 and 1587, though it is not recorded if he held that title for all the years in between.He probably went with his father to Guisnes in 1553; certainly he was there when the French declared war in 1557; his eyewitness account of his father's last desperate defence of Guisnes, after Calais itself has fallen, remains the best source for the episode.Like his father he became a hostage but was ransomed a year later.
