I want to know the answer to the following question:
To what rank was Eisenhower promoted on July 7, 1942?
All the background I'm provided with is that "On June 23, 1942, he returned to London as Commanding General, European Theater of Operations (ETOUSA), based in London and with a house on Coombe, Kingston upon Thames, and replaced Chaney.". Is that enough to answer the question?
