How did the Germans go to such lengths to destroy Britains Empire?

During WWI, Germany's only thought was to gain total domination of the world. The Germans especially wanted to take control over the most powerful nation, the British. The British were mainly so powerful due to their high-class navy. And Germany wanted to attack that navy. With only seventeen cruiser ships spread out in the oceans, Germany found some way to defeat the British. One of the only reasons Germany was able to do this great task was because as the German ship and the British ship were in a race to victory, the British wanted their fastest ship out there, however it was not equipped with the best guns. Thus, the German ship destroyed the small ship. Germans also used a trick against the British and their allies. When German ships were out at sea and a British or a British ally was drawing near, the Germans would put up a dummy funnel to disguise the ship as a British ship. Therefore, when the opponent came near the Germans were able to attack without any warning.With these different tactics, the Germans successfully sunk two British ships.
