LVT – Landing Vehicle, Tracked Amphibious Tractor or AmphTrac or Amtrac or “Alligator”
Flame Throwers – Filled with Napalm – Gasoline mixed with naphtha that sticks to flesh and burns extremely hot flames.
Iwo Jima (Nimitz) 9 Feb 1945 Objective: Capture Airfields 1st wave of Marines gets ashore easily but then Japanese attack. 2 days - Southern half of island in US control. Takes 34 more days to secure remainder (8 square miles total).

What “trends” can you identify? Using the data below, create a bar graph or line graph showing U.S. casualties in the Pacific theater in WWII. What “trends” can you identify? Make a prediction of the casualties of an invasion of Japan. Battle American Dead American Wounded Tarawa (Gilberts) 1,001 2,300 Guam (Marianas) 3,000 7,000 Saipan (Marianas) 3,426 13,160 Iwo Jima 6,000 17,200 Okinawa 12,500 35,500 Japan ????? ?????
1945 February-March Iwo Jima (Nim.) March Tokyo raids Low level fire-bombing runs. Kills 80,000 Japanese civilians Designed to force surrender but didn’t. April-June Okinawa (Nim.) Japanese home island – very tough resistance August 6th Hiroshima 9th Nagasaki 15th Japan surrenders. September 2 VJ Day
A New Formula for Mass Destruction Japan warned, but refused to surrender. Planners estimate 3-5x as many casualties as at Okinawa. Hiroshima 6 August 1945 60-70k killed or missing Nagasaki 9 August 40k killed Logical outcome of “Total War”?
