IWO JIMAFEBRUARY – MARCH, 1945

BACKGROUND IWO JIMA:

LOCATION: 750 mi. SOUTH OF TOKYO CONSIDERED ONE OF JAPAN’S “HOME ISLANDS” (define) USED BY JAPANESE AS PART OF “INNER” DEFENSE LINE (unlike Tarawa,

Guadalcanal, etc.) OCCUPIED & FORITFIED BY JAPANESE MILITARY SINCE 1930’s

AFTER THE BATTLE OF THE PHILIPPINE SEA(1944): JAPAN REALIZES IWO JIMA GARRISON MUST BE STRENGTHENED BECAUSE…A U.S. ATTACK ON HOME ISLANDS IS IMMINENT (define) SO…

MORE TROOPS SENT MORE EQUIPMENT SENT FORTIFICATIONS STRENGTHENED

RESULT? IJA/IJA TROOP STRENGTH (February,’45) = 22,800 (approx.) MASSIVE UNDERGROUND TUNNEL/BUNKER NETWORK JAPANESE DEFENSES: MIXTURE OF…

HEAVY ARTILLERY LIGHT WEAPONS MORTARS CONCEALED BUNKERS / “MURDER HOLES”

BACKGROUND (cont’d.) LATE ‘44/EARLY ‘45:

U.S. MILITARY INCREASES AERIAL BOMBING CAMPAIGN ON HOME ISLANDS

U.S. NEEDS TO CONTROL IWO JIMA (& other islands – ex. OKINAWA)

WHY? IWO HAS LARGE AIRFIELD COMPLEX AIRSTRIPS WOULD PROVIDE…

BASE FOR U.S. BOMBERS TARGETING JAPAN SHORTEN AERIAL DISTANCE TO JAPAN PROVIDE EMERGENCY LANDING STRIPS FOR DAMAGED U.S.

AIRCRAFT BASE FOR LONG-RANGE FIGHTER ESCORTS

JAPANESE WERE USING ISLAND FOR AERIAL ATTACKS ON U.S. FLEET

ISLAND WOULD BE USED AS A NAVAL / AIR / SUPPLY BASE FOR INVASION OF JAPAN

FORCES HAVE LANDED INFLICT AS MANY CASUALTIES AS POSSIBLE NO RELIEF FROM MAINLAND EXPECTED NO SURRENDER
