Commando Comic #4714 'The Last Big Gun' (2014)
 
Jean D'Arton of the Free French Army had watched the giant railway howitzers plummet to destruction and was convinced these devastatingly powerful weapons were out of the war for good.
 
Now, though, information from the Resistance suggested that the Germans had salvaged at least one of these titanic guns.
 
And with the Allied invasion of France due any day now, Jean just hoped these reports weren't true.
