In January 1937, the survivors of No.1 Company joined with 450 new British, Irish, and Dominion volunteers at Madrigueras, near Albacete, International Brigades headquarters. They were formed into an English-speaking battalion, with three infantry companies (Nos. 1, 3, 4) and a machine-gun company (no. 2). Canadian Bert "Yank" Levy served as an officer in No.2 company of the Saklatvala Battalion, under Wintringham from 1937. He was captured at the Battle of Jarama and spent six months in a Francoist gaol until he was released in a prisoner exchange.
