CN Created - Sat, June 6 @ 01:00 (-1d, 10h, 5m)
Today marks 107 years since the creation of the Canadian National Railway, today known simply as CN, in 1919. It is Canada's largest railway, including significant trackage in the United States.
   
D-Day - Sat, June 6 @ 01:00 (-1d, 10h, 5m)
On this date in 1944, Allied troops landed on the beaches of Normandy, in Operation Overlord; the "D-Day" landings. American, British and Canadian troops landed on five beaches, establishing a foothold on the continent and fighting their way inland. Canadian troops reached the furthest inland on that day. Artificial harbours were soon constructed, and fuel pipelines laid on the sea bottom from England to France. Hundreds of thousands of soldiers arrived in Europe in this way. The attack was the beginning of the end for Germany, with the Russians closing in from the east, and now the Allies growing in strength, liberating France and moving up the Italian Peninsula.
