Photo Story Challenge: Letter “U”

This week, Frizz challenge is for the letter “U”….

Uhhhhh…It is quite complicated!!!! But I have remembered one nice thing I have seen in the “Museum of Science and Industry of Chicago”..

“U” stands for “U-505”

An U-boat is a submarine…The abbreviation comes from “unterseeboot”, a German word that means “undersea boat”…

U-boats were a terrible menace for the Allied ship´s, and they were really elusive..To get an idea, this only U-505 sank eight Allied ships in 1942. So, they became one major target for them..

The U.S. Navy organized special antisubmarine escort ships in units called Hunter-Killer Task Groups.The U-boat 505 was captured by the Guadalcanal Task Force, leaded by Captain Daniel Gallery (from Chicago) on June 4, 1944, North of the Cape Verde Islands.

It was a really important capture: being intact, it allowed the Allies to study it and being able to defend their ships better..And what is more, it was a wonderful source of intelligence: apart from acoustic torpedoes,  it had two Enigma machines inside, as well as codebooks…That saved a lot of hours of decoding work to the Allies!

It is the only U-boat of its type in the States, and one of the only five left in the whole world. Now,  in Chicago, it is a memorial to the 55.000 American sailors who died in the Atlantic Ocean during the WWI and the WWII..
