Bombing Japan from Marianas - NOV 1944
At a cost of ~3000 American and 24,000 Japanese lives, the Northern Marianas island of Saipan was taken in July 1944. With the subsequent seizure of Guam and Tinian in August, the U.S. now had ideal locations (~1500 miles from Japan) to construct airfields within the range of the new B-29 superfortress (~5000 miles). Additionally, these new airfields could be directly supplied by ship from the USA.
