Seventy five years ago, the exact time and place of the D-Day invasion was a closely guarded military secret, but the fact that is was coming soon was no secret. 75 years ago today, the May 20, 1944, issue of the Milwaukee Journal carried this headline that Gen. Eisenhower had issued his first orders to the Underground.

The orders went out over American radio stations recently constructed on the continent.  The commander-in-chief advised the underground to take minute and detailed note of every move of the enemy, with particular attention to the moves of his men, tanks, guns, as well as their markings and strength.

When this was published, the invasion was just over two weeks away.
