The Americans needed the airfields and needed the island to marshal forces for an invasion of the Japanese mainland .
In terms of number of ships , the Okinawa invasion fleet was larger. In terms of casualties the number was far greater at Okinawa. The US Navy deaths were higher than Marines or Army.
A lot of people died :(
Okinawa
Yes, by 20,000 men.
On April 1st, 1945, the last major invasion in the pacific for the US was the battle for Okinawa
Okinawa
Japan
battle of okinawa
It allowed the American airforce to reach further into Japan.
the Japanese dug an tunnel network under ground on a huge scale to avoid bombings from allied ships, before the invasion of Okinawa.
roughly 4 to 5 thousand depends on condition
The Normandy D Day was far larger than the D Day for Okinawa. Over 5000 ships and hundreds of planes and hundreds of thousands of troops were involved in the Normandy Invasion. The invasion on Okinawa was peanuts compared to that.
