1835. HMS Beagle arrives at the Galapagos Islands. Aboard is Charles Darwin, whose work there will result in the fame of both the man and ship.
1862. An element of the scattered Confederate forces in Maryland capture Harper's Ferry. General McClellan presumably attended to his laundry.

1935. Jews are deprived of their citizenship in Germany as a result of the enactment of the Nuremberg Laws. Germany adopts a new flag, with a swastika.
1950. General Douglas MacArthur's crowning achievement -- the landing at Inchon, Korea. The highly dangerous amphibious assult deep behind North Korean lines (still pressing US and S.
