the crew were killed, although twelve Germans managed to escape, including the captain. This was possible due to the Catalina's crew, who threw a lifeboat to the survivors. "1st Fighter Group", which saw action in Italy, was formed on December 18, 1943. Its commanding officer was Aviation Lt.Col. Nero Moura. The group had 350 men, including 43 pilots. The group was divided into four flights: Red ("A"), Yellow ("B"), Blue ("C"), and Green ("D"). The CO of the group and some officers were not attached to any specific flight. Unlike the BEF's Army component, the 1º GAVCA had personnel who were experienced Brazilian Air Force pilots. One of them was Alberto M. Torres, who had piloted a PBY Catalina that had sunk U-199, operating off the Brazilian coast. The group trained for combat in Panama, where 2º Ten.-Av. (Aviation Second Lieutenant) Dante Isidoro Gastaldoni was killed in a training accident. On May 11, 1944, the group was declared operational and became active in the air defense of the Panama Canal Zone. On June 22, the 1º GAVCA traveled to the US to convert to the Republic P-47D Thunderbolt. On September 19, 1944, the 1º GAVCA left for Italy, arriving at Livorno on October 6. It became part of the 350th Fighter Group of the USAAF, which in turn was part of the 62nd Fighter Wing, XXII Tactical Air Command, of the 12th Air Force. The Brazilian pilots initially flew from 31 October 1944, as individual elements of flights attached to 350th FG squadrons, at first in affiliation flights and progressively taking part in more dangerous missions. Less than two weeks later, on November 11, the group started its own operations flying from its base at Tarquinia, using its tactical callsign Jambock. Brazilian Air Force stars replaced the white U.S. star in the roundel on the FAB Thunderbolts. The 1oGAVCA started its fighting career as a fighter-bomber unit, its missions being armed reconnaissance and interdiction, in support of the US Fifth Army, to which the FEB was attached. On April 16, 1945, the U.S. Fifth Army started its offensive along the Po Valley. By then, the strength of the Group had fallen to 25 pilots, some having been killed and others shot down and captured. Some others had been relieved from operations on medical grounds due to combat fatigue. The Group disbanded the Yellow flight and distributed the surviving pilots among
