this and the size of the Japanese garrison. It was important to
demonstrate that the Japanese could be beaten not only in carrier
actions, but also in the difficult fighting environment of the Pacific
islands, while, for Pacific campaigns to succeed, it was necessary to
show that air and sea support could be provided to amphibious
forces, both when landing and subsequently. In addition, Coral Island
and Midway had been defensive successes, but, at Guadalcanal, the
attack had clearly been taken to the Japanese and, despite much
effort, they had been unable to hold the position.
Also, the time taken to defeat the Japanese on the island, and the
large number of islands they continued to hold, ensured that it would
be necessary to focus American efforts carefully, a policy that required
the identification of key targets. Thanks to a growingly apparent
American superiority in the air and at sea, the Japanese would be less
able to mount ripostes and any bypassed bases would be isolated.
Thus, the Pacific war was to become one that was far from linear.
In eastern New Guinea, American and Australian forces finally
prevailed in particularly arduous fighting conditions: the jungle, the
mountainous terrain, the heat, the malaria and the rain combined to
cause heavy casualties. Amphibious and overland attacks led to the
capture of Salamaua and Lae in September 1943. The Allies had
benefited from intelligence gained by interceptions, as well as from
gaining control of the air, to which this intelligence and the absence
of radar to help protect Japanese airfields greatly contributed.
Combined with Guadalcanal, this success ensured that Australasia
was protected and prepared the way for further Allied attacks. The
Japanese still had substantial forces in New Guinea, and there was
fighting there until the end of the war, but successive positions were
taken, in part thanks to amphibious operations.

Heavy Japanese losses of aircraft and crew over Guadalcanal
helped the Americans seize the initiative in 1943, as they began a
process of island-hopping in the Solomon Islands in June with an
attack on New Georgia. Carriers played a major role, but so also did
the creation and securing of airfields.They were important not only
for their attack role, but also as part of the far-flung American
command and control and supply systems. The value of air power
had been dramatically displayed on 3–4 March 1943, when a convoy
carrying troops to reinforce New Guinea was attacked by American
