8

How did America's killed and wounded on Iwo Jima compare with the Japanese garrison's?

10

How did Iwo Jima's Japanese garrison get most of its drinking water?

Catching rain in concrete cisterns was the mainstay on an island with no springs or streams, and the garrison spent months on short water rations before the landing.

36

Baron Takeichi Nishi, who died commanding a tank regiment on Iwo Jima, had won Olympic gold in 1932 in which sport?

The Marianas put Japan within bomber range, but Iwo Jima sat halfway along the route, and aircraft based there had been raiding the American airfields.

What did American planners believe Iwo Jima's radar station was doing?

Warning of raids was the charge, up to two hours ahead by one Marine account; the Navy's historians now call that assumption wrong.

Jack Lucas, 17, became the war's youngest Medal of Honor recipient on Iwo Jima for doing what?

Kuribayashi's defence in depth on Iwo Jima copied tactics Japanese troops had used months earlier in which battle?
