Brazil was the only independent South American country to send ground troops to fight in WW2, with over 25,000 soldiers.
The Brazilian Expeditionary Force consisted of about 25,700 men arranged by the army and air force to fight alongside the Allied forces in the Mediterranean Theatre of World War II. This air-land force consisted of (replacements included) a complete infantry division, a liaison flight, and a fighter squadron.
It fought in Italy from September 1944 to May 1945, while the Brazilian Navy as well as the Air Force also acted in the Battle of the Atlantic from the middle of 1942 until the end of the war. During the almost eight months of its campaign, fighting at the Gothic Line and in the 1945 final offensive, the FEB took 20,573 Axis prisoners, consisting of two generals, 892 officers, and 19,679 other ranks. Brazil was the only independent South American country to send ground troops to fight overseas, losing 948 men killed in action across all three services during the Second World War.
