The first period was a continuation of Lodge's longtime service as an Army Reserve Officer. Lodge was a major in the 1st Armored Division. That tour ended in July 1942, when President Franklin D. Roosevelt ordered congressmen serving in the military to resign one of the two positions, and Lodge, who chose to remain in the Senate, was ordered by Secretary of War Henry Stimson to return to Washington. During this brief service, he led a squadron of American tankers at Gazala; they were the first Americans to engage German troops on land in the war.
