Archaius I found that bit about Hartmann and The P-51s Enjoy.
Q: When did you first encounter the American pilots?
A: This was in the defense of Ploesti and Bucharest, and also over Hungary when the bombers came in and they had heavy fighter escort. I was recalled to take over the command I/JG-52, and this was 23 June 1944. B-17s were attacking the railroad junction, and we were formed up. We did not see the Mustangs at first and prepared to attack the bombers. Suddenly four of them flew across us and below, so I gave the order to attack the fighters. I closed in on one and fired, his fighter coming apart and some pieces hit my wings, and I immediately found myself behind another and I fired, and he flipped in. My second flight shot down the other two fighters. But then we saw others and again attacked. I shot down another and saw that the leader still had his drop tanks, which limited his ability to turn. I was very relieved that this pilot was able to successfully bail out. I was out of ammunition after the fight. But this success was not to be repeated, because the Americans learned and they were not to be ambushed again. They protected the bombers very well, and we were never able to get close enough to do any damage. I did have the opportunity to engage the Mustangs again when a flight was being pursued from the rear and I tried to warn them on the radio, but they could not hear. I dived down and closed on a P-51 that was shooting up an 109, and I blew him up. I half rolled and recovered to fire on another of the three remaining enemy planes and flamed him as well. As soon as that happened I was warned that I had several on my tail so I headed for the deck, a swarm of eight Americans behind me. That is a very uncomfortable feeling I can tell you! I made jerking turns left and right as they fired, but they fired from too far away to be effective. I was headed for the base so the defensive guns would help me, but I ran out of fuel and had to bail out. I was certain that this one pilot was lining me up for a strafe, but he banked away and looked at me, waving. I landed four miles from the base; I almost made it. That day we lost half our aircraft; we were too outnumbered and many of the young pilots were inexperienced.
