“[At Guadalcanal, t]he U.S. Navy lost twenty-four major warships; the Japanese lost twenty-four. Aircraft losses too were nearly equal: America lost 436, Japan 440. Ashore, U.S. Marine and Army killed were 1,592 . . . . The number of Americans killed at sea topped five thousand. Japanese deaths set a bloody pace for the rest of the war, with 20,800 soldiers lost on the island and probably 4,000 sailors at sea.
“It was the most critical major military operation America would ever run on such a threadbare shoestring. . . . [T]he puzzle of victory was solved on the fly and on the cheap, in terms of resources if not lives. The campaign featured tight interdependence among warriors of the air, land, and sea. For the infantry to seize and hold the island, ships had to control the sea. For a fleet to control the sea, the pilots had to fly from the island’s airfield. For the pilots to fly from the airfield, the infantry had to hold the island. That tripod stood only by the strength of all three legs. . . . For most of the campaign, Guadalcanal was a contest of equals, perhaps the only major battle in the Pacific where the United States and Japan fought from positions of parity. Its outcome was often in doubt.”
