The Walloon Legion (French: "Légion Wallonie" ) was a collaborationist volunteer unit recruited from Belgium's French-speaking population in Wallonia and Brussels during the German occupation of World War II. The Walloon Legion served in the Wehrmacht, later in the Waffen-SS, on the Eastern Front on both front line and reserve duties. Using only the above description and what you know about the world, "Some volunteers from Brussels served in the Walloon Legion." is definitely correct, incorrect, or inconclusive?
