became the supreme commander of the allied expeditionary force.
served in the pacific theater under general douglas macarthur.
ceded his position to general george patton.
retired from the military and public service in general.

Explanation:

After serving as the commander of US forces in Europe, Dwight D. Eisenhower became the supreme commander of the Allied Expeditionary Force. This was a key role in the planning and execution of major military operations during World War II. Serving in the Pacific Theater under General Douglas MacArthur is incorrect as his main focus was in Europe. Ceding his position to General George Patton is also wrong as there was no such transfer in that context. Retiring from the military and public service in general is not what happened immediately after his role as US forces commander in Europe.

Answer:

became the supreme commander of the Allied Expeditionary Force.
