While Middleton was helping LSU recover from this traumatic ordeal, he was also keeping an eye on events in Europe. In July 1940 he wrote a letter to General George Marshall asking if his services were needed by the Army as the United States was making preparations for war. Marshall replied that as much as the Army would like to have Middleton back in uniform, all the Army could do would be to place him in some training role, which would not effectively use his battle experience.
