Pizarro urged attack, starting the Battle of Cajamarca. The battle began with a shot from a cannon and the battle cry ""Santiago!"" The Spaniards unleashed volleys of gunfire at the vulnerable mass of Incas and surged forward in a concerted action. Pizarro also used cavalry charges against the Inca forces, which stunned them in combination with gunfire. Many of the guns used by the Spaniards were however hard to use in close combat. The effect was devastating, the shocked Incas offered such feeble resistance that the battle has often been labeled a massacre, with the Inca losing 2,000 dead and Spanish having just 1 soldier wounded.
