Overview
Enemy Ace first appeared in Our Army at War # 151, (February 1965) It was a backup story that quickly gained popularity. As a World War I pilot flying for the Germans, his stories told the German side of the war, in which Hans von Hammer was a man of honor and chivalry, a flying knight in his Fokker Dr.I, but he was haunted by his duties and the constant death surrounding them.
The early series stories centered around World War I Air Combat and the strategies, tactics and honor employed by the early knights of the air. The stories were often a stark contrast between the dark brooding character Von Hammer and his softer, kinder side as in Star Spangled War Stories No 148 where Von Hammer rescues a little dog he names "Schatzi" and proceeds to befriend him, even introducing him to his dark hunting companion the gray wolf who accepts little Schatzi rather than eating him. But the Von Hammer stories were not big on happy endings, and Von Hammer goes on to lose Schatzi in a haunting scene by dropping him accidentally from his Fokker during air combat. He grieves the loss of the dog, then proceeds to massacre the remaining British pilots in an act of bloody revenge. Von Hammer was a dark character, portrayed as the inevitable result of war.
Unlike most comic book characters, Von Hammer does not have an arch-enemy, though a French pilot known as The Hangman was a persistent opponent. The majority of Von Hammer's opponents followed the same code of honor as he did, which included not attacking a helpless pilot.
Created by Robert Kanigher and Joe Kubert, the Enemy Ace was taken loosely from the real-life Red Baron, Manfred von Richthofen. Both flew Crimson Red Fokker DR1 Triplanes. Both were of aristocratic blood. Both awarded themselves a trophy with each downed enemy plane. Both were the highest scoring flying ace of the First World War. The main difference between the two was that Von Hammer survived to old age, whereas Von Richthofen was shot down and killed before the war ended.
The character's stories have been praised as among DC's strongest war stories of the Silver Age of comic books. He was revived for a few graphic novels. The first was Enemy Ace: War Idyll (1990) by George Pratt, where Hammer is revealed to have lived until 1969, dying peacefully upon turning over his memoirs and concluding his interviews with a troubled Vietnam War veteran-turned-journalist.
A more recent work is Garth Ennis's Enemy Ace: War in Heaven (2001), with art by Chris Weston and Russ Heath. Here, von Hammer's character and story arc is based on several real-life German pilots', notably Adolf Galland. The series recounts the pilot's activities during World War II where he is persuaded to once again fight as a pilot of the Luftwaffe. Von Hammer is placed in charge of his own gruppe and initially serves on the Eastern Front. Though no friend to the Nazi regime, he rapidly amasses numerous kills flying a red-painted Me-109 against the Russians, and later in defense of Germany (flying a scarlet Me-262) against American bombers. Nevertheless, von Hammer becomes increasingly disillusioned as he continues to witness the horrors of war. In 1945, after bailing out of his damaged aircraft, he inadvertently parachutes into the Dachau concentration camp and is outraged to discover the German perpetration of the Holocaust. He proposes a mutiny upon returning to his airbase and later surrenders his Jagdverband to advancing Allied troops, namely Sgt. Rock's company, after setting fire to the fighter unit's remaining aircraft.
Recently, in issue #139 of the latest Robin series, von Hammer's great-granddaughter Lieutenant Ilsa von Hammer appeared as part of a group of soldiers that included Johnny Cloud's grandson and a legendary soldier known only as the Veteran. This group, handling missions which may be more unusual than the normal military is equipped for, recruits Robin to assist on their missions.
Another possible descendant appears in Superman #689. Will Von Hammer works as a private investigator in Berlin. He possesses some superhuman invulnerability as he is also the descendant of World War II hero Stormy Foster.
Von Hammer makes a guest appearance of sorts as an opponent of General Wade Eiling's father in a tale set during the First World War
In 2008, he is featured in Bruce Jones' The War that Time Forgot. He also appears in Booster Gold in 2009, during World War I. When Booster is thrown back in time and caught in the middle of the war, alongside Cyrus Lord, the ancestor of Maxwell Lord, von Hammer aids their escape from captivity behind German lines rather than abet their torture and further stain his hands with blood.
