In 1539 an English mercenary, Nicholas Bagenal, fled to Ireland after murdering a man in Leek, Staffordshire, apparently with the aid of his two brothers. After some time in the employment of the O Neill he reached a high status, was granted a pardon in 1543, and became Marshal of the army. During his early years in the Louth area he lived at Carlingford where his son Henry was born. Lord Bingham is seen sending Oriel labourers to Newry in 1546 at which time Bagenal is seen restoring the castle of Newry, which belonged to Hugh O Neill, being first built by John De Courcy in 1186 (De Arcy McGee See also Lewis 1815). Not long after this the Marshal, in 1552, secured a 21-year lease on the Newry property, which was confiscated from the Cistercians. The castle was then razed to the ground by Shane O'Neill, who banished Bagenal from Newry in 1566.
