The Blacker Bombard, also known as the 29-mm Spigot Mortar, was an infantry anti-tank weapon devised by Lieutenant-Colonel Stewart Blacker in the early years of the Second World War.
Intended as a means to equip Home Guard units with an anti-tank weapon in case of German invasion, at a time of grave shortage of weapons, it was accepted only after the intervention of Churchill. Although there were doubts about the effectiveness of the Bombard, many were issued. Few, if any, saw combat.
