How did Germany plan a blockade British ships?

Germany planned a blockade against British ships primarily through the use of U-boats, or submarines, to target merchant vessels and disrupt supply lines. The strategy, known as unrestricted submarine warfare, aimed to sink any ship, including neutral ones, entering British waters. This tactic was intended to weaken Britain's economy and military supply, ultimately contributing to Germany's war efforts during World War I. However, the blockade also led to significant diplomatic tensions, particularly with the United States, due to the loss of civilian lives.
