I want to know the answer to the following question:
When did the United States land forces on Okinawa?
All the background I'm provided with is that "The Japanese, with 115,000 troops augmented by thousands of civilians on the heavily populated island, did not resist on the beaches—their strategy was to maximize the number of soldier and Marine casualties, and naval losses from Kamikaze attacks.". Is that enough to answer the question?
Answer: no
