In the late 1880s John Maxim developed the first modern machine gun, the Maxim gun. It was incredibly powerful and reliable. In its first actual use in Rhodesia, 50 trapped British soldiers with four Maxim guns killed 50,000 native soldiers attacking them in less than 30 minutes without loss to a single British soldier. The Brits, led by Major David Wilson, wiped out an invincible army. Wilson later led a battalion against the same type of gun in WW 1 and his entire battalion was wiped out.
