Today, Bruns lectured and I listened. it was sooooooooo much fun. This is what he talked about.
10. How US/Allies fought back against U-boats
We built faster ships to outrun them. Convoy system; ships travelled in large numbers. Ultra and Magic. Hunter-Killer ships and airplanes. Depth charges.
11. Intelligence gathering--Ultra/Magic
Trying to intercept and decode messages. Radar helped detect vessels and aircraft, HF/DF used to located sources of enemy radio transmissions; submarines. Ultra and Magic were the codenames for intercepting and deciphering German and Japanese codes. German; Ultra. Japanese; Magic. British and American trackers worked together to locate Axis powers using these. Enigma; German system that transferred their code, solving it's code was one of the great Allied triumphs of world war II. British "Bombe" decoded it.
12. Operation Barborossa(USSR vs Germany)
Hitler invaded Soviet Union because of Lebensbraum. (living space) Wanted Ukraine for farmland, use people as slave labor, defeat of USSR would further isolate the Allies. He wanted the oilfields in the Caucasus mountains. He didn't trust Stalin. German propaganda showed that Stalin was planning to attack Germany. He also hated all the ethnic Slavs ruled by their "Jewish Bolshevik" masters.
