Giachino was not dead, but very badly wounded. An Argentine combat medic, Corporal Ernesto Urbina, attempted to get to Giachino but was wounded by a grenade. Giachino, seeing what had happened, pulled the pin from a hand grenade and threatened to use it. The Royal Marines then attempted to persuade the officer to get rid of the grenade so that they could give him medical treatment, but he refused, preventing them from reaching his position. After the surrender of the British forces at Government House, some three hours later, Major Giachino was taken to Stanley Hospital but died from loss of blood.
