Despite the fact that he was personally an anti-Nazi, by serving Hitler, men like him helped destroy monarchism in Germany as a vital force.
From The Mad Monarchist (25 June 2015)
During World War II, one of the most successful fighter pilots in the German Luftwaffe was Prince Heinrich zu Sayn-Wittgenstein. His accomplishments were all the more remarkable in that he was a night fighter pilot and an ace who won most of his victories against the British. Whereas most of the highest-scoring German aces achieved most of their "kills" against the Russians on the Eastern Front, victories won over the RAF were more difficult and thus much more prestigious. This was the category that Prince Heinrich fit into. In his time, he was the most successful night fighter pilot in Germany and most of his victories were won against the much more formidable Royal Air Force of Great Britain. He was also no great fan of the Nazi regime and even contemplated assassinating Adolf Hitler personally. Read his story below.
He first saw action in World War II as an observer and navigator with the bombers fighting in the invasion of France and the battle of Britain. The following winter he went through special training for night flying, something he was to excel in. When Hitler invaded the Soviet Union he was stationed in East Prussia and was involved in the destruction of the Russian airfields in the Baltic states. By the summer of 1941 he was already a highly decorated veteran of 150 combat missions. In January of 1942 he transferred to the night flying wing and was promoted to squadron commander, winning his first victories over the Netherlands. Some of his comrades said that Wittgenstein was too strict, vainglorious and lacked the qualities of a teacher and mentor that were required of a good officer. However, none could deny his talent and his score of victories quickly soared. In October of 1942 he was awarded the Knight’s Iron Cross. Moving back to the Russian front in 1943 his successes became even more numerous. Later in the year though he was transferred west again to provide cover for Allied air assaults on the German submarine bases on the French coast.
His victories and reputation continued to rise and he and his squadron were moved back to the east where he was further decorated by Adolf Hitler himself. However, the prince was not exactly flattered by this attention from the Nazi dictator. In fact, he confided to his mother that his disgust with the Nazi government had grown so great that he contemplated assassinating Hitler when presented with his award. He reasoned that he had no wife or children to leave behind and would have the perfect opportunity. However, his sense of duty to his country prevailed and he did not follow through on his threat. Not long after, on January 21, 1944 he was shot down near Berlin by British fighter escorts, going down with his plane after having his crew parachute to safety.
More decorations were posthumously added to the long list of honors Prinz zu Sayn-Wittgenstein received during his career. At the time of his death he was the most successful night fighter pilot in the entire German air force and even by the end of the war only two other pilots had managed to surpass him. In all he shot down over 80 Allied aircraft and won most of the awards the Luftwaffe had to offer. Unlike many of the most successful German pilots he won more engagements on the western rather than the eastern front. Initially buried in Germany he was later moved and reburied in the Netherlands.
