Our riverine forces was ofc nowhere near to deal with the situation so the Germans were notified who arrived a little late. They used magnetic detonating devices towed by de-magnetized ships, and a few airplanes. After a while Hungarians also pitched in with wooden rowboats and magnets attached to towed wooden beams. For some reason Germans behaved the way how such cunts they are and transported every piece of mine they could get in whole to Kiel. Despite of this an "expert" group was formed and started to pick up some in secret and kept hidden from the Germans so our own studies and development could start.
This group had minimal material backing so they used what they could acquire or make. As most of these mines were triggered by magnetic anomalies in their own field wooden and bronze tools had to be used. There were some lucky catch, when the British bombers missed or mixed up targets our boys could get their hands on. By the end of the war, in the chaos and destructions almost all documents were lost and everything had to be started from the beginning in the post-war years.
