Leslie Richard Groves (August 17, 1896 - July 13, 1970) was the United States Army general who oversaw the construction of the Pentagon and the primary military leader in charge of the Manhattan Project to develop the atomic bomb during World War II.

General Leslie Groves's opinion that the German Freedom Front did not have the resources to build an atom bomb, despite having Germany's top physicists in their possession, carried a substantial amount of weight, helping to diffuse Republican critics of the Truman Administration.

With the arrival of the Race's Conquest Fleet in 1942, the completion of an American atomic bomb became that much more important. Thus, the pressure was on for Leslie Groves to see the project to completion. He accepted a sample of plutonium from a British submarine in Boston Harbor. He carried the plutonium to Denver, where he turned it over to the US physicists working on an atomic bomb. Groves remained in Denver as commander of the Manhattan Project until that project's completion. He designed the defenses of Denver when the Race advanced on that city in 1944. Those defenses were implemented by Omar Bradley. Groves oversaw the Battle of Denver alongside Bradley.
