However, the focal length is simply not clear, so it must be adjusted to twice the focal length. At the focal length, the distance of five and a half miles and the height of the benchmark should be.

This thing is really troublesome to calculate, but the accuracy is quite high.

After a while, he finally raised his hand and said loudly: "Five and a half miles away, turn the rudder to the west, the artillery on the right, the angle of elevation is twenty-six, deflect the left five, load the armor-piercing bullets, and prepare for a volley."

"Brush" a wave of order flags. The warship under his seat began to turn around and sailed to the gunboats on the local area again. The cabins on each floor were also in waves. The gunner on the right was adjusting the angle of the cannon according to his instructions, loading shells, and preparing to open fire.

This time is different from last time. Last time they were crossing the enemy head-on, but this time they chased them up. Both sides were driving in the same direction, and the bombing time must be much longer than last time.

He quickly turned around and completed his car's course, and the direction of his enemy warship was exactly the same.

At this time, he ordered without hesitation: "Accelerate, move to the second gear, and chase after it."

A "slam" sounded, and the four water wheels began to accelerate. His car accelerated instantly and would soon catch up with the last enemy's tower ship gunboat.

That's now!

He raised his hand and shouted: "Open fire, fire a round of volleys on the right side, and continue to load armor-piercing bullets."

"Boom boom boom", the roar of artillery sounded again, and this time they were still the first to open fire.

Although Putmans was in the middle of the fleet, he had already turned around and raised his telescope to pay attention to the movements of the enemy ship. When the enemy ship began to turn around and follow him, he did not order to open fire because he already understood that both sides seemed to have entered the range of each other, but in fact there was still a little distance. Last time, these guys opened fire first, which made him misjudgment, thinking that both sides had entered the range of each other's fire, so he fired a round of volleys, wasting thousands of shells.

This time, he would no longer be foolish in firing with the enemy.

After all, the number of shells they carried was limited, and the ability of the gun barrel was also limited. It would take a while for a few guns to be cooled down. Moreover, the accuracy of the shells in naval battles was generally scary. He didn't know how many rounds he had to fire to repel the enemy's fifty tower ships. At this moment, he could not fire randomly and waste shells.

At this time, he had discovered that the enemy's tower ship gunboat was not a sailboat, but a huge wheel boat!

In other words, the enemy can turn around without relying on the wind direction and water flow, and they are all sailboats, making it very difficult to turn around.

He seemed to have seen that the enemy's tactic was to keep turning around and fire the guns on both sides in turn. This would save shells and give the barrels enough cooling time, which would facilitate long-term combat.

At this time, he cannot be fooled by the enemy and blindly fight against others. Once the gun barrel needs to cool down, the enemy will only be beaten.

In other words, he must determine that the enemy ships actually enter the range of range before they can fire the gun. Otherwise, they are likely to be fooled by the enemy and waste shells in vain, which will also cause the barrel to overheat and will not be able to fight back for a period of time.

So, did the enemy ship really enter the range this time or did it fire randomly to lure him into firing the cannon?

It is very simple to determine this. Just look at the approximate range of the water column aroused after the enemy shells fall.

At this time, the thirty tower ships and warships were already lined up in a straight line. He could not see the last warship, and he could only roughly judge the distance between the two sides based on the range of the water column.

"Boom boom boom" After a roar of cannons, a pile of water quickly aroused on the sea surface.

Putmans held up the telescope and swept his face suddenly changed.

This time, the water column of enemy shells splashed was actually next to the last gunboat on his side!

In other words, the enemy has really entered the range this time, and the last gunboat on its side is likely to have been shot!

He quickly ordered: "Hurry, send orders, all the gunboats in the building ships fire in turn, and the firepower on both sides will be fully activated. As long as the enemy enters the range, fire the gun!"

"Boom boom boom".

"Boom boom boom".

The continuous roar of artillery sounded again, and the two sides entered a new round of confrontation.
Chapter completed!
