Jürgen Wattenberg's Leather Provision Bag

Origin
Jürgen Wattenberg was a German naval officer and U-boat commander during the Second World War. In a successful career spanning just under a year, he sank 14 ships, a total of 82,027 gross register tons. He initially served on the Admiral Graf Spee until the captain scuttled it in neutral Uuguay to avoid immediate and battle against stationed British cruisers. Wattenberg later commanded U-162 at age 41, making him one of the oldest U-boat commanders during the war. He achieved several successes before his U-boat was attacked and sunk by British warships. Taken prisoner once more, Wattenberg was imprisoned in the United States, where he contrived to escape again, spending over a month at large. He was released after the end of the war and settled in Germany, where he died in 1995, aged 94.
