✹ About Martin Beckman Paul Beckmann on 19 Sep 2015 • Link I'm pretty certain he was never Master Gunner of England. He served in Ireland and was present at the Siege of Athlone (in which he directed the siege artillery) and was also present at the Battle of Aughrim (in which he may have directed some of the heavier field artillery). He was responsible for the capture of Colonel Blood in his abortive attempt to steal the Crown Jewels. Blood asked him to assist in the education of his son, Holcroft Blood, as a military engineer. Colonel Holcroft Blood, as he became, directed the Duke of Marlborough's artillery at the Battle of Blenheim.
