Commando Comic #4449 'Days Of Danger' (2011)
 
Simon Katz was a young German and a fervent anti-Nazi. A brilliant mathematician, he escaped Germany by the skin of his teeth and went to work as a code-breaker for the British.
 
Not long after, Sergeant Barney Taft also made an escape - from the bullet-strafed beaches of Dunkirk.
 
Though they were on the same side, when circumstances threw the pair together, they clashed bitterly. But could they manage to work together against a ruthless enemy? They would have to if they were to survive.
