Three hours and forty minutes later, five minutes ahead of schedule, the submarine was in its intended position, and by this time it was close to evening, and Captain Hafs put the submarine into a semi-submersible state, and the lookout went up to the conning tower and searched the convoy with binoculars. If the convoy hadn't spotted his submarine before that and had sailed in its original course, he would have been able to see the merchant ships again in about thirty minutes, according to his budget.

The rest of the crew were also ready for battle, everyone was waiting for the appearance of the prey, and the time became extraordinarily long, although it was only a few tens of minutes, but in the waiting, such a time was stretched for a long time. Because the submarine had lost visual contact with the fleet in the previous few hours, if they had changed course during those hours, it would have been useless for the U-11 to travel for several hours.

It was about four or five minutes later than expected, and the convoy finally appeared.

"Spot the enemy fleet, distance, direction, speed!" Finally, the watchman's shouts came from the intercom.

"Prepare to dive to a depth of thirty meters, speed 5 knots, direction 006, ready for battle!" Captain Hafs looked at the charts and immediately gave the order, the alarm sounded inside the submarine, the lookout hurriedly left the control tower, closed the watertight hatch, and the soldiers went to their places.

"The submarine has reached a depth of thirty meters." Boatswain Harlan shouted.

Captain Hafs looked at his watch, looked at the charts again, and then ordered: "Reduce the speed to 1.5 knots!" ”

The submarine began to slow down slowly, and before raising the periscope, the submarine needed to slow down as much as possible, because if the submarine was too fast, when the periscope came out of the water, it would pull out a clear track, which was almost equivalent to shouting to those who wanted to hunt the ship, or the ship that wanted to hunt it, that I was here. So, before sticking out the periscope, the submarine had to slow down a bit.

In a sense, Hafs felt that submarines were like crocodiles in Africa when he was in school. This terrible animal is actually not the top in terms of running speed or swimming speed, and its endurance is also average. They can neither defeat the running antelope in the competition of speed like the cheetah, nor can they force a cheetah to die of exhaustion in the run by relying on endurance like the black Kenyans. They can only sneak up on rivers or pools where the animals have to drink, and when the animals do, they sneak under the water and strike a blow. It's the same with the submarine, it can only stay on the course and wait for those ships to enter its fish. Thunder's range, and then a burst of blows. In this sense, a submarine is a crocodile on the sea. It's just that as long as the crocodiles stay in the water, they basically have no natural predators, as long as they don't mess with the big, cautious hippos, and with a little luck, they don't get seen by the leather dealers, basically no one will pose any threat to them. But this is not the case with submarines, and the threat posed to submarines by destroyers that run fast is quite large. Therefore, Hafs sometimes even envies those crocodiles.

"It's slowed down to 1.5 knots." Someone shouted again.

"Good, go up to periscope depth and stick the periscope out." Captain Hafs said.

There was a sudden rumbling sound in the submarine, the sound of compressed air pressing a portion of the sea water out. In most cases, the submarine only needs to maintain a density similar to that of seawater, and can control the depth of the submersible by operating the rudder surface. But now, the speed of the submarine has dropped significantly, which makes the efficiency of the rudder surface also drop a lot, so it is necessary to use this method to adjust the density of the submarine slightly.

Soon, Captain Hafs got a report: "It has risen to periscope depth, and the periscope has been extended." ”

Captain Hafs walked to the periscope and began to turn the periscope to look at the target at sea.

Hafs saw the merchant ships approaching in the course he had envisioned, and did not realize that he was stepping into an ambush circle of U-11s.

"This speed, this angle, it's perfect, it's like a textbook." Hafs thought to himself slightly.

The merchant ships were getting closer and closer, and at this time, Hafs noticed that there were two more destroyers next to the merchant ships.

"These nasty things." Hauffs thought, "Let's use the four fish in the bow of the ship in a moment. Thunder hit a fan and then turn it in a circle and put the tail of the two fish. Thunder quickly knocked out, and then hurried away before the two destroyers arrived. ”

"Bow fish. Is Ray ready? Hafs asked.

"Fish No. 1. Thunder. Tube ready! ”

"Fish No. 2. Thunder. Tube ready! ”

Soon, four fish. Thunder. The tubes are all ready. Hafs carefully controlled the submarine, while his subordinates were busy calculating the amount of advance and angle of fire. Soon, everything was ready.

"Launch the fish. Ray ......," Captain Hafs ordered.

With a roar of compressed air, four fish. Ray shot from the bow of the U-11.

"Put away the periscopes, turn, let's prepare for the second round!" Hafs shouted.

The periscope was retracted, the electric motor was turned on to maximum power, and the submarine began to accelerate in the water, turning. According to Hafs's calculations, when they completed this turn, the fish that had just been launched. It should be another three minutes or so for Ray to hit the target. So they still have time to put the remaining two fish. Thunder strikes out. Fish that use compressed air as power. Thunder will have a very obvious track, but fortunately there are still some waves in the sea today, although this may cause fish. The yaw of the thunder, however, can also help to a large extent to cover the fish. Ray's tracks.

The U-11 quickly made the turn and Hafs caught the clock to shoot the last two fish at the merchant fleet. Thunder.

"Good!" Hafs shouted, "Put away the periscope, dive to 40 meters, turn in the direction of 90." Accelerated to 8 knots, decelerated to 1.5 knots after six minutes, and ascended to periscope depth. ”

The U-11 put away the periscope and began to dive, and if there were no escorts in the fleet, Hafs would continue to stay at periscope depth and use the periscope to admire the fish. The beauty of the merchant ship hit by the thunder will even make the rest of the crew take turns to enjoy it through the periscope. It is said that one captain even did something to float a submarine up and get the sailors to come out and cheer at an enemy transport ship that was exploding and sinking. Of course, this guy was later locked up and promoted because of this. So Hafs wouldn't be like that.

And now, there are escort destroyers on the enemy's side. Under such conditions, it would be too dangerous to continue to maintain the periscope depth and stick the periscope out of the water for sightseeing. Therefore, Hafs planned to immediately dive to a relatively safe depth, and quickly run away. At this time, safety comes first.

In the process of running away, the U-11's listening receiver heard three explosions in succession. This shows that his attack was very successful, six fish. Three of the mines managed to hit the target.

After six minutes, the U-11 slowed down to reduce the noise. By this time the British destroyers should have arrived just now when they launched the fish. Ray is in a position where he is now probably listening to the sounds around him with a listening device, and slowing down and reducing the noise is a must.

The U-11 sailed at a low speed for another ten minutes, and the submarine's hearers did not hear the characteristic abrupt sound of the destroyer's propellers, and it was clear that the British had not been able to find them.

The U-11 quietly raised its periscope to determine the outcome of the battle. Hauffs saw that there were two boats that were fished. Thunder hit, one of them was a standard container ship, the ship had tilted so much that Hafs was sure it wouldn't be long before the ship sank. The situation was even worse on the other boat, whose bow had been lifted slightly out of the sea. The bulbous bow painted ochre-red is revealed. There were a number of lifeboats not far from the boat, and some of them even took the risk of slowing down and lowering more lifeboats into the sea.

"Damn, it looks like a passenger ship!" Hauffs thought.

Before Hafs launched an attack on the flotilla just now, he did not see this passenger ship, it was blocked by other ships. Fish. Ray wasn't actually aimed at it, but it was hit, and depending on its current state, the ship would sink in a few minutes at most, and Hafs was almost certain that at least half of the people on the boat wouldn't have had time to get out......

……

Originally, a passenger ship was sunk and more than 200 civilians died, which is not a big deal. It is now the time of the Great War, and thousands of people are killed on the battlefield every day, and the civilian casualties caused by long-range artillery on both sides are far more than that. In addition, civilians are not impossible to fight, and most of the killings of the German Zeppelin are also civilians. But, damn it, the ship was a passenger ship from England to the United States, and most of the passengers on board were Americans!

Both the British and the Germans are well aware of the decisive role of the power of the United States, the world's largest industrial nation, in today's situation. In this war, whichever side the Americans fall towards will inevitably win. So as soon as it happened, the British immediately jumped up and shouted "the Germans slaughtered the Americans" or something. And claim that such an attack has been planned for a long time and is aimed at the United States.

The Germans also made public the results of the investigation into this tragic misunderstanding in the shortest possible time, and the results showed that the sinking of the Anne was a complete accident, and who let the passenger ship get mixed up in the formation of cargo ships? The Germans also unceremoniously accused the British of deliberately mixing such a passenger ship with a cargo ship in order to lure the Germans into hitting it by mistake. In order to trick the Americans into the thief ships of the British.
