I want to know the answer to the following question:
What event contributed to Eisenhower receiving a promotion to brigadier general?
All the background I'm provided with is that "Although his administrative abilities had been noticed, on the eve of the U.S. entry into World War II he had never held an active command above a battalion and was far from being considered by many as a potential commander of major operations.". Is that enough to answer the question?
Answer: no
