So that's how Pele ended up in a German POW camp
I thought he suffered a far worse fate.... playing for the New York Cosmos.
Brazil played a significant role in the fight against the U-boats in the South Atlantic as well as being a critical staging point in the air route to West Africa and on to Egypt. U-boats preying on Brazilian shipping was what caused Brazil to enter the war, although the USAAF and US Navy staged out of northern Brazil well before the declaration of war.
I think the reference to Brritish refusal of warships relates to the Great War, Brazil being unique amongst South American nations in being a belligerent power in both wars. Both British built battleships, Minas Gerais and São Paulo were out of action by the outbreak of WWII, they served as floating batteries. Actually the only time either of them ever fired its guns in anger was against the government in Rio de Janeiro.
