William Mills, a hand grenade designer from Sunderland, patented, developed and manufactured the “Mills bomb” at the Mills Munition Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland. Roland and Mills were later engaged in a patent lawsuit. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915, and designated as the No. 5.
