Richard Scrope fought in the major theatres of Henry V's French campaign, bringing fifteen men-at-arms and forty-five archers to the Battle of Agincourt and commanding a naval section at the Siege of Harfleur composed of barges and balingers. His last years were spent defending the north-east coast of England against the threat of Scottish sea attacks; in 1418 he was based in Kingston upon Hull with 120 men-at-arms and 240 archers.
