The Marine landings on Guadalcanal may have caught the Japanese military by surprise, but it shouldn’t surprise us in the least that they, at this stage of the Pacific War, responded rather quickly. We’ve already talked a bit about the Japanese “response from the air”, but their surface vessels weren’t far behind.
In addition to all the aircraft stationed at Rabaul, the newly-formed Japanese 8th Fleet had also dropped anchor there. This force of cruisers and destroyers was commanded by Vice Admiral Gunichi Mikawa, a steady and rational leader. When messages of invasion began coming in from Tulagi on the 7th of August, he immediately gathered his men, hoisted the anchors, and made for the Solomons.
Mikawa’s plan for a night attack during the evening of August 8/9 gave his immediate superiors pause, and for good reasons. There was precious little information coming from Guadalcanal concerning the size of the enemy forces. Were there carriers?…battleships? It was assumed that the transports would be well-protected, and Mikawa’s fleet, while powerful, might be signficantly smaller than that of the U.S. Navy. And while the Japanese were excellent naval night-fighters, fighting an unknown enemy at night was fraught with peril. But Isoroku Yamamoto, knowing Mikawa to be a cautious fighter with a good head on his shoulders, gave his blessing. Mikawa was off…reaching Bougainville at dawn on the 8th, where they were spotted by Australian reconnaissance.
Meanwhile, on the other side…
As the night of August 8th was ending, the U.S. leaders were meeting. General Vandegrift (in charge of the Marines on Guadalcanal) met with Admiral Fletcher and Admiral Turner (Fletcher’s boss). Turner informed Vandegrift that Fletcher was moving his carriers to the south due to reports of Japanese forces coming from the north. Vandegrift was livid…there were still tons of supplies to be unloaded for his troops on the island, and leaving them now would put them in a terribly vulnerable position. But Fletcher had already made up his mind and Turner backed him. Vandegrift would have to get settled in, at least for the moment, on his own.
Savo Island is small and conical-shaped, sitting about 10 miles off the northwest coast of Guadalcanal. And from the north, Mikawa’s forces were closing in for the kill. Now General Vandegrift hadn’t been left totally alone. British Admiral Victor Crutchley’s fleet of cruisers and destroyers were operating near Savo as a screening force, and it was they who were punished by the Japanese.
I say “punished”, because that’s precisely what Mikawa’s smaller force did in the early morning hours of August 9, 1942. Crutchley’s forces didn’t spot the enemy first, and when they did, they were concerned about firing on their own ships. The Japanese Eighth Fleet used this small window to tremendous advantage.
When the sun rose on Savo the following morning, four heavy cruisers had been sunk, with another badly damaged. Nearly 1,100 sailors had perished. And Mikawa’s forces were long gone, have suffered little damage and 58 killed.
Much has been made of Mikawa’s decision to withdraw. His opposition had been plastered, and there was nothing between him and the largely exposed (and mostly helpless) 1st Marine Division just forty or fifty miles away. He polishes off the enemy ships, moves a bit south, lays waste to the Marines with heavy gunfire, and the Guadalcanal operation is an unmitigated U.S. disaster two days after it starts. The U.S. campaign in the Pacific would have been set back indefinitely.
But Mikawa was operating at night with only the information he had. He knew there were enemy carriers out there, he just didn’t know where. It never entered his mind that Fletcher had moved (or even would move) them south, and reconaissance couldn’t locate them. The Admiral also knew he had no carrier support with him, and against enemy carriers he would have been at a colossal disadvantage. So while it was a terrible mistake on his part to pull back, his decision (made at 2:20 in the morning) was the right one.
The landings on Guadalcanal and the capture of its airfield were a real boon to U.S. military morale…the first time U.S. forces had taken the fight to Japanese-controlled soil. The Battle of Savo Island was a sobering reminder of just how tough and resourceful the enemy was gonig to be.
