I think I'm proof against rehashing any old topics, after a search here https://www.alternatehistory.com/forum/search/3415343/?q=iwo+jima&o=date&c[title_only]=1

  • The tunnel linking the mountain to the main forces was never completed
  • The day the Americans invaded, 11 miles of a planned 17 miles of tunnel network had been dug.
  • The Japanese supply was inadequate. Troops were supplied a 60% of the standard issue of ammunitions sufficient for one engagement by one division, and food and forage enough for four months.
  • IJA had 21,060 total men under arms vs. 110,000 USMC men
So, let's give the Japanese the following:
  • Tunnels are completed as designed
  • Troops have sufficient ammunition and food
  • 50,000 IJA troops
How is the battle impacted? It's still going to be a loss for the IJA of course.
