His mother, Princess Walburga, commented that: “… he was boundlessly disillusioned and boundlessly disappointed. In 1943 he contemplated the thought of shooting Hitler. It was only out of sense of honor and duty that Heinrich went on fighting, carried along by the ambition to overtake Major Lent in his score of enemy aircraft shot down”.
In her memoirs, Tatiana von Metternich reported that Wittgenstein planned to kill Hitler after the ceremony at which he received his Knight’s Cross of the Iron Cross in 1943. He said, “I am not married, I have no children—I am expendable. He will receive me personally. Who else among us can ever get as near to him?”
The Bf 110 served with success in the early campaigns: the Polish, Norwegian and Battle of France. The lack of agility in the air Bf 110 was their main weakness. This defect was during the Battle of Britain, when some units equipped with Bf 110 aircraft were withdrawn from the battle after suffering heavy losses and redeployed as night fighters, a function that the plane adapted very well. The Bf 110 enjoyed a successful period after the Battle of Britain as an air superiority fighter and attack aircraft on other fronts. During the Balkans Campaign, the Campaign of North Africa and the Eastern Front, he provided valuable air support to the ground troops of the German Army as a potent fighter-bomber (Jabo-Jagdbomber). Later it was developed into a formidable night fighter, becoming the largest aircraft of the Luftwaffe night operations. Most German night fighter aces piloted the Bf 110 at some point in their careers combat, and the greatest night fighter ace of all time, the largest Heinz-Wolfgang Schnaufer, piloted this model only and has allocated 121 victories 164 combat missions
