On the morning of August 29, 1940, while the Battle of Britain raged in the skies overhead, a small group of men boarded an ocean liner and left the country with the nation’s most sensitive military secrets.

These men were not spies or Nazi sympathizers. They were among the United Kingdom’s foremost civilian and military scientists, and they were headed for Washington, D.C. in an attempt to turn the tide of the war, which at that point was going very heavily in favor of Nazi Germany.
