The Allies sunk German Uboats. Uboat, not you-boat. Uboats stand for Unterseeboot - undersea boat.
The Caprivi Strip provided the Germans access to the Zambezi River.
German Empire is just a term used to denote all things relevant to Germany. So, just the fact that Germans started a society is what allowed the Germans to create a German empire.
