During his term, Camacho faced the difficulty of governing during World War II. After two of Mexico's ships (Potrero del Llano and Faja de Oro) carrying oil were destroyed by German submarines in the Gulf of Mexico, Camacho declared war against the Axis powers on 22 May 1942. Mexican participation in World War II was mainly limited to an airborne squadron, the 201st ("Escuadrón 201"), to fight the Japanese in the Pacific. The squadron consisted of 300 men, and after receiving training in Texas, it was sent to the Philippines on 27 March 1945. On 7 June 1945, its missions started, and the squadron participated in the Battle of Luzon. By the end of the war, 5 Mexican soldiers had lost their lives in combat. Despite its short participation in the war, Mexico belonged to the victorious nations and had thus gained the right to participate in the postwar international conferences.
