Part (a) - What happened at the Battle of Midway [4 marks]

• The Japanese navy, under Admiral Yamamoto, planned to capture Midway Island and destroy the remaining US Pacific Fleet in a decisive engagement.
• American codebreakers had deciphered Japanese naval codes, allowing Admiral Nimitz to know the time and place of the attack and set a trap.
• American dive-bombers from the carriers Enterprise, Hornet and Yorktown caught the Japanese carriers while their aircraft were being refuelled and rearmed on deck - a moment of maximum vulnerability.
• Four Japanese fleet carriers - Akagi, Kaga, Soryu and Hiryu - were sunk. The Americans lost one carrier, the Yorktown.

Part (b) - Why the loss of four aircraft carriers was devastating for Japan [6 marks]

• Core of offensive power: Fleet carriers were the backbone of Japan's naval strike capability. Their loss crippled Japan's ability to project air power across the vast Pacific Ocean.
• Industrial limitations: Japan's industrial capacity was far smaller than America's. Building new fleet carriers took years, and Japan could not replace its losses at anything like the rate the United States could build new ships.
• Irreplaceable aircrew: Along with the ships, Japan lost hundreds of experienced pilots and aircrew who could not be quickly replaced. Japanese naval aviation training programmes were slower and less extensive than American ones.
• End of offensive capability: Without its carrier force, Japan could no longer launch the major offensive operations across Pacific distances that its strategy required.
• Strategic initiative lost: The balance of naval power shifted permanently to the United States, which could now take the offensive while Japan was forced onto the defensive.

Part (c) - How far was Midway the turning point of the war in the Pacific? [10 marks]

Midway as the turning point:

• Before Midway, Japan had been on the offensive, conquering territory across the Pacific and Southeast Asia with apparent ease. After Midway, Japan was permanently on the defensive.
• The battle shifted the balance of naval power to the United States, which could outproduce Japan in ships, aircraft and trained personnel by a large margin.
• Intelligence (codebreaking) proved decisive, establishing a pattern of Allied advantage that continued throughout the war.

The war was far from over after Midway:

• Fierce fighting lay ahead at Guadalcanal (August 1942 - February 1943), through the island-hopping campaign in the Central and South Pacific.
• The battles of the Philippine Sea (June 1944) and Leyte Gulf (October 1944) further destroyed Japanese naval power.
• The costly assaults on Iwo Jima and Okinawa in 1945 demonstrated that Japan would fight tenaciously despite its strategic disadvantage.
• Japan did not surrender until the atomic bombs and the Soviet declaration of war in August 1945.

Midway was the point at which the tide turned - the moment when Japan lost the strategic initiative and the ability to win the war. However, translating that advantage into final victory required three more years of intense fighting and enormous resources. The turning point and the endpoint of a war are rarely the same moment.
