Question

man in the middle... the allies knew that they needed the us supplies to continue their fight. they created a blockade (british blockade) as a way to “barrier” off german naval attacks against us trading ships. but the blockade was only a temporary success due to the height of german technology - the u - boat. 12. what is a u - boat and why were they effective? 13. these things, though primitive early in history, did some serious damage. but what were their weaknesses?

Explanation:

1. A U - Boat is a German submarine used during World War I. They were effective because they could operate stealthily underwater, allowing surprise attacks on Allied shipping, disrupting supply lines which were crucial for the Allies' war effort.
2. Early U - Boats had limited endurance and range, were vulnerable when surfaced (for re - charging batteries and taking on supplies), and communication was difficult while submerged.

Answer:

1. A U - Boat is a German submarine. They were effective due to stealthy underwater operations and ability to surprise - attack shipping.
2. Weaknesses included limited endurance/range, vulnerability when surfaced, and communication difficulties underwater.
