"An account of the “epic human tragedy” that unfolded when Allied troops landed on the shores of Normandy on D-Day"
Stopped reading there. Google: "By the end of the first day, none of the assault forces had secured their first-day objectives. Allied casualties on June 6 have been estimated at 10,000 killed, wounded, and missing in action: 6,603 Americans, 2,700 British, and 946 Canadians."
10k killed on your worst day? "an epic loss"?
The Soviet Union lost like 15k people. Per day. Over a week, a month, a year, in the end, over 5 years. It was a German-Russian war in Europe and the "Omaha Beach" looks more like a birthday party for children.
