Career
She actively participated in sabotage actions against the British Army. Many Italians (like Amedeo Guillet ) fought a guerrilla war in the "Africa Orientale Italiana", after the surrender at Gondar of the last regular Italian forces in November 1941. They fought in the hope of an Italian victory with the help of Rommel in Egypt and in the Mediterranean that would originate a possible return of the Axis in Eastern Africa.
In August 1942 she managed to enter the main ammunition depot of the British Army in Addis Abeba and blow it up, somehow surviving the huge explosion.
This act of sabotage destroyed the ammunition for the new British Sten submachine gun and delayed the deployment of this "state of the art" weapon for many months. Doctor Dainelli was famous as one of the few Italian women who participated actively in the Italian guerrilla operations against the British troops after the East African Campaign (World World War II).
She was nominated, after the end of the war, for the Italian iron medal of honor ("croce di ferro").
