With his first appearance in Our Army At War #151 in February 1965, Hans von Hammer, was one of DC's most unforgettable war heroes created by writer Robert Kanigher and artist Joe Kubert. The son of a German aristocrat, the young Baron was one of the first to enlist when World War I broke out in 1914. A model Third Reich soldier, von Hammer quickly excelled in flight school over the envy of his peers, causing an early duel of honor with a fellow cadet that gained his permanent scar on his left cheek. One of the greatest natural pilots to be seen, this "Hammer of Hell" as the Allied forces called him was soon appointed as Rittsmeister of his own Jagdstafell. Over the long and deadly years of the war, this "Enemy Ace" had over seventy confirmed kills to his credit, much to his dismay for this endless loss of life. A solitary man who kept to himself, he took no joy in his new found fame performing his grisly duties for the Fatherland. When not flying, von Hammer would aimlessly roam the grounds of his estate in the Black Forest, with his only true companion, a huge grey wolf.
