The battle in the sky continued, and the American bomber group, relying on its advantage of being rough and thick-skinned, gradually approached the target that was already not far away, the oil field facilities in Romania.

The unexpected addition of Soviet bombers did buy time for the American bomber group, and it also made the Germans cramped in the amount of ammunition again. After all, there were not many pilots as powerful as Hartmann on the entire German Eastern Front, and more of them were at the level of normal ace pilots, so most of the German fighters did not deliberately save ammunition when attacking.

In fact, under normal circumstances, if a fighter uses up half of its ammunition and shoots down a large bomber like a B-17, it can already be said to be a very good level, of course, German fighter pilots have developed good combat habits of saving ammunition, so their results are better. However, it was still only possible to ensure that 15 to 25 shells could shoot down one American plane, and only about three planes could be shot down before one plane ran out of ammunition.

This is also why there are still many American planes that have not been shot down, because the B-17 bomber is too strong. In another time and space that Accardo knew, it often happened that the B-17 was beaten into a sieve by German fighter jets and could still staggering back to the British base. It can be said that this kind of aircraft is about the same level as a tank in the sky, and it is easy not to crash.

If it weren't for Accardo's foresight, the prescient preparation of large-caliber aircraft guns for Germany in advance, and the pilots who were accustomed to using these aerial guns, then what today's interception operation would have become, just look at the bombed-out Romania in another time and space.

"Stop fighting with these bombers! Get out of these bombers, and if you continue to fight like this, the other side will enter the sky above the chemical plant area! Break away! Break away! Regroup! Regroup at an altitude of 11,000 meters! Quick!" The latest operational instructions came from the headphones on the ears of the pilots of the German planes.

"Break away? Is there a mistake? We broke up the opponent's flight formation after we ran out of rockets, and now we break away and let the other side regroup? If we fight a second time, the other side will enter the oil field area!" An ace pilot who had just bypassed the American bomber frowned and questioned the order.

More pilots immediately flew their planes, broke away from the American bomber formation, and flew to the designated airspace not far away, where they assembled into a new fighter formation to prepare for a second dive strike on the American bomber group.

With a deep sense of reluctance and regret, the German pilots all made the choice to obey the order, they flew their planes, and began to regroup not far away, while the American bombers also began to adjust their formation and reorganize the defense system at this time.

It is a pity that there are only 3 P-40 fighters left in the escort, and the poor flight is among the B-17 bombers, and it is not known who is protecting whose safety.

"Why are you retreating? Who's in command?" a major squadron leader finally found his men in the formation high altitude, he had just joined the battle with only one wingman, and now he saw that his unit was missing two planes, and it looked like two poor unlucky bastards from the dozen planes that had just been shot down.

A slightly deeper voice came from the headphones, but it was audible to almost all the pilots: "I'm Catherine, it's my order to regroup!

After this period of delay, the German ground forces were ready to meet these uninvited guests, and the mobile anti-aircraft artillery units deployed on the railways and roads entered the firing area, and the 88-mm cannon raised its barrel high and pointed it into the sky, ready to fire to greet the enemy from afar.

Famous in North Africa for their anti-tank capabilities, these anti-aircraft guns were called the best weapons in the hands of the Germans by Patton.

Less than a minute after the German planes left the American aircraft formation, the anti-aircraft artillery fire placed by the Germans on the ground suddenly opened fire, and the radar-guided anti-aircraft artillery units showed unparalleled destructive power, allowing these American pilots who came from afar to see what the real wave of unsettled waves was.

Although there is no super invention such as a radio proximity fuze, because the function of radar has been developed very perfectly, the altitude and speed of American aircraft have been easily calculated, and the shells used by these anti-aircraft guns on the ground have set the explosion height before firing, and the hitting accuracy is definitely not much lower than that of proximity fuse shells.

Before the American pilots could take a breath to relax their nervous mood, shells rained down on these American planes, and the American planes that had just formed their flight formations once again withstood the baptism of a storm, and their planes were hit by the exploding shrapnel, and many shooters were hit by shrapnel and died on their own combat posts.

"Jack, I don't think we're going to be able to do what we planned, and even if we could start dropping bombs now, the Germans wouldn't suffer much damage, and the number of bombers left would not be enough to completely paralyze an oil field. Powell, the front-line commander of the bomber unit of the US Army Air Force, looked at the already fragmented bomber formation, and said with some frustration: "You should start returning immediately with the injured plane." ”

The Czechman was the front-line commander of the fighter unit, and most of his men had been shot down by German planes, and now only he and his wingman were left, as well as an ace pilot born in the air war in North Africa. He sighed and said, "It's too late! Even if I turn around now, I won't have a chance to fly back." You know how fast those German planes were. ”

"I have a higher rank than you, and I order you to cover the two wounded B-17s out of here! Now, right now!" Powell, who was piloting the bomber, said forcefully: "Let's return immediately!"

"......" silence, or suffocating silence, Jack knew that this was the last chance of escape left to him by his old friend Powell, and this was already a battle to the death, so there was no need to take some inconsequential losses. Finally, Jack glanced at the rain of bullets outside the cabin, smiled wryly, shook the joystick to the left, and gave a combat order that he was most reluctant to give: "Return!"

The three fighters and the five B-17 bombers that were slightly damaged broke away from the entire aircraft formation and fled in a hurry in the other direction, and the German fighter groups, which were busy blocking the American bombers and preventing them from entering the airspace of the oil fields, did not have the idea of chasing and killing the deserters, and almost tacitly let go of the American planes that escaped.

However, with the onslaught of two rounds of anti-aircraft guns, the American bomber force was on the verge of collapse, and they were left with only a pitiful 49 of them, and most of them had holes in the wings of the fuselage. The turret on the back of the worst plane had been shattered by shells, and the body of the pilot hanging inside was still shaking in the seat, looking terrifying.

There are bombers in good condition, and there are also parts that are not in good condition and can no longer fly, and these American bomber pilots are ready to sacrifice themselves in this foreign land to do their best for the future of their country.

On such occasions, in the heat of battle, even cowards would be motivated to fight to the fullest, and all the American shooters were on standby, and the bombers had accelerated towards their targets, not paying attention to the smoke dragged by the friendly planes that hit.

"God bless the United States! I can't get close to the target anymore! I open the bomb bay! I started dropping bombs!" When he saw that his planes were constantly decreasing, and the German fighters above him had begun to dive and attack, and the losses were getting bigger and bigger, and they could no longer hold on to the real target, Powell finally gave the order to attack, and his voice was very tragic, and he seemed to have made up his mind to fight a life-and-death battle with these pilots.

With the sound of mechanical friction, the American bombers finally showed their hideous fangs, and when they were ready, in the shocked eyes of the German pilots, one bomb after another left the cabin of the B-17 bomber by gravity, which was the first time that the Allies dropped bombs in a heavily fortified German air defense zone.

"It's still a little close! These bombs can't reach the designated bombing targets! We must keep flying!" The bombardier looked at the sights and said with some regret: "Fly for a few minutes, and we will be able to accurately hit those factories!"

"Steady! I'm going to lower the altitude! Even if I die, I'm going to drop these bombs on the heads of the Germans!" Powell gritted his teeth and said fiercely: "Permission to parachute! Those who are willing to leave can leave now! Good luck to you!"

In the telescope of the officer of the German ground observation station, an American plane rushed straight to a German chemical factory in Romania by inertia, and no matter how many ammunition fighter jets poured on it, the plane still rushed towards the plant.

This is the persistence and persistence of a bomber pilot, and this is also the faith and courage of an American. None of the crew members chose to parachute ahead of schedule, and they held out to the last second in their combat posts! In the end, the attack of the Americans did work, and their planes crashed into the courtyard wall of the factory and blew up the corner of a warehouse. The fire was raging, and the Romanian air defense system, which was fortified by the Luftwaffe layer by layer, was finally nominally broken through by the Americans.
