Which Latin American countries contributed troops to WWII?

Brazil was the only Latin American country that contributed troops to World War II.

During the Second World War, Latin America was largely divided in its support for the Allied and Axis powers. However, Brazil was the only Latin American nation that actively contributed troops to the conflict. In August 1942, Brazil declared war on Germany and Italy, aligning itself with the Allies. This decision was influenced by a series of attacks on Brazilian merchant ships by German U-boats, which led to significant public outrage and a shift in the government's stance.

Brazil's military contribution to the war was significant. The Brazilian Expeditionary Force (BEF), also known as the "Smoking Snakes", was composed of about 25,000 men and women who served in various capacities. The BEF was deployed to the Italian Campaign, where they fought alongside the Allies against the German and Italian forces. They played a crucial role in the Battle of Monte Castello and the final Allied offensive in Italy, known as the Spring Offensive.

In addition to the BEF, Brazil also provided logistical support to the Allies. The country's strategic location along the South Atlantic made it an ideal base for anti-submarine warfare. The United States built air bases in Brazil, from which they launched patrols to protect Allied shipping routes. Brazil's naval and air forces also participated in these patrols, helping to secure the South Atlantic against Axis submarines.

While other Latin American countries declared war on the Axis powers, none of them sent troops to fight. Instead, their contributions were largely symbolic or limited to economic and logistical support. For example, Mexico declared war on the Axis in 1942 and contributed resources and labour to the Allied war effort, but did not send any combat troops. Similarly, Argentina, despite maintaining a policy of neutrality for most of the war, eventually declared war on Germany and Japan in March 1945, but did not contribute troops.

In conclusion, Brazil was the only Latin American country that contributed troops to World War II, playing a significant role in the Italian Campaign and providing crucial logistical support in the South Atlantic.
