"At about 9:30 p.m. (21:30 hours) on the evening of June 4, 1944, Eisenhower called a meeting at his command post at Southwick House in Portsmouth, England. A storm with high winds and rain had forced a one-day postponement of the invasion, originally set for June 5. Eisenhower had learned from his meteorological staff that there would be a break in the weather and that the next day, Tuesday June 6, would be more favorable. He considered all the variables. General Montgomery, his ground commander, favored taking the risk. After a long silence, Eisenhower gave the command, "Okay, we'll go."
