"It's magnificent, this is the essence and strength of a century-old empire. "The S-85 reconnaissance airship was hidden in the black night sky, and even if it was not by moonlight, at an altitude of 3,000 meters, the German naval officers and sailors on the airship could still clearly see the British fleet that was returning home, because the British fleet sailing in the night did not implement light control, and the huge fleet composed of more than 30 battleships, more than 20 cruisers of various types, and more than 4 dozen destroyers was withdrawing towards the mainland.www.biquge.info

"Captain, the British fleet is starting to disperse!" A moment later, one of the crew members pointed to the two fleets that were scattering in the distance. Three hours after the end of the battle, the British Rapid Fleet and the Main Fleet finally separated, and the huge fleet, which had been like a splendid sea city, was divided into two groups, one large and one small, and sailed to Shetland Islands and Forth Bay respectively.

"Three hours later, in the C5 area, the British fleet began to disperse, and the average speed of the British fleet before it was around 15 knots. The British fleet did not implement radio silence and did not implement light control. The captain of the S-85 wrote in his battle record.

The reason why the German airship could easily determine its position in the North Sea at night was still relying on the radiolocation system called Salzburg, and with the strong support of the prince, Germany's radio technology was actually no worse than that of the British, and it can be said that both sides had their own strengths. The British have an advantage in a single piece, while the Germans are strong in system integration, relying on 36 radio direction finding and ranging stations distributed along the coast of the German mainland and the coast of Belgium, which can not only provide night navigation for their own submarines and airships, but also roughly determine the orientation of the British fleet with the cooperation of airships.

"The British fleet went very slowly, and after four hours of sailing, they reduced their speed to about 14 knots. And often make irregular Z-shaped maneuvers, presumably to avoid ambushes from our submarines. But on the whole, they chose the nearest route to sail. Moments later, the S-90 succeeded the S-85 and continued to track the British Rapid Fleet.

However, about 150 kilometers from the port, the British fleet abruptly abandoned its previous caution and chose to return in a straight line, and a moment later, the S-90 airship spotted a group of planes flying from the direction of the British mainland. As they approached the fleet, the group of more than 20 planes turned on their fuselage searchlights almost simultaneously, and oval-shaped pillars of light swept back and forth across the sea.

"At about 11:30 p.m., 130 kilometers away from the British Forth of Forth, the British land-based aviation sent planes to respond, the number is very large, about 2 dozen, from the analysis of the aircraft outline, there are V1500 4-engine large aircraft, and V400 twin-engine aircraft, but the largest number is the Felixstowe F2A 4-engine large seaplane, their main task should be anti-submarine." The captain of the S-90 airship also recorded in the combat report the measures and steps taken by the British when they retreated.

"Okay, let's fly higher, I don't want to go head-on with these guys with machine guns all over their bodies, like an oversized flying hedgehog." After the British fleet sailed to a distance of less than 70 kilometers from Forth Bay, more and more aircraft appeared in the sky, and at this time the S-90 airship chose to increase the altitude to 4500 meters.

However, while the airships in the air were staring at the fast fleets and planes of the British. Submarines on the surface of the sea in a semi-submerged state are also carrying out tasks that do not have any attack but are still very important.

Several German naval personnel opened the sealed hatch and carefully moved over the slippery surface of the submarine, several laboriously opening a large curved antenna along the steel lift-and-shrink rod, while inside the submarine, several naval technical officers were busy on an instrument. Although they were around the course of the British fleet, they did not make any attack.

After all, the carrying capacity of the airship is limited, and the radio equipment on it cannot cover all the frequency bands used by the British, so at this time it must be supplemented by other means, and at this time, the submarine that can also avoid most of the reconnaissance means of the British Navy can play a role. (What?) Why didn't the planes of the British spot this submarine? Please, there was no radar in the 1st World War, just by relying on searchlights, it was enough to drive away submarines around the fleet 3000 meters, and you still want to find German submarines dozens of kilometers away? What do you think? ）

"Finally found them!" An officer with a beard rubbed his hands excitedly. "Let the brothers above turn the wire to 10 o'clock!" The officer walked over to the passage of the submarine and said to his colleagues outside the control tower.

Then, several soldiers laboriously rotated the antenna, which was 3 meters in diameter. After the rotation is completed, don't forget to fix it with the bracket.

"At 30 kilometers outside the Forth of Forth the submarine of the British, in addition to this point, there are three other points, which are connected together to form an arc with the Forth of Forth as the center. This was supposed to be the cordon of submarines deployed by the British off the coast of Forth Bay. "The bearded officer marked on the chart the location of the British submarine that had just determined the approximate position, this positioning is very inaccurate, generally speaking, the error can be calculated in kilometers, and if you want to anti-submarine, you can only know the approximate location of the other party.

"Here, look at these pictures." The captain took out several other charts and then used a different colored pencil with the officer to mark on one chart the positions of the British submarines identified by the previous reconnaissance.

"Although there are some changes, they are generally offshore alerts, and their cordons are generally in a circular area with a radius of 15 to 40 kilometers from the center of the base. The number of submarines deployed by the British in the Forth Bay was not large, and the gap was relatively large. The captain wrote in his report after comparing the information collected several times.

When the British Rapid Fleet returned to Forth Bay, the eyes that were scattered in the air and beneath the surface of the sea were also withdrawn. Over the next few days, a large amount of information was sent back to the German Navy's base camp in Wilhelmshaven through various channels.

"Well, in the next 3 weeks we need to adjust the whole fleet to the best condition, and if we can, I hope that every ship can be maintained to a certain extent, and when Moltke and Saxony are back in the group, that's when we strike again. Believe me, next time, it will definitely not be a petty fight, those battlecruisers will no longer be able to satisfy our appetites! At the end of the next day's battle summary meeting, the prince said in high spirits.
