The firing on Betio had barely subsided before apocryphal claims began to appear in print that the four eight-inch naval rifles used as coastal defense guns by the Japanese were the same ones captured from the British at the fall of Singapore. Many prominent historians unwittingly perpetuated this story, among them the highly respected Samuel Eliot Morison.
In 1977, however, British writer William H. Bartsch published the results of a recent visit to Tarawa in the quarterly magazine After the Battle. Bartsch personally examined each of the four guns and discovered markings indicating manufacture by Vickers, the British ordnance company. The Vickers company subsequently provided Bartsch records indicating the four guns were part of a consignment of 12 eight-inch, quick-firing guns which were sold in 1905 to the Japanese during their war with Russia. Further investigation by Bartsch at the Imperial War Museum produced the fact that there were no eight-inch guns captured by the Japanese at Singapore. In short, the guns at Tarawa came from a far more legitimate, and older, transaction with the British.
The eight-inch guns fired the opening rounds in the battle of Tarawa, but were not by themselves a factor in the contest. Earlier bombing raids may have damaged their fire control systems. Rapid counterbattery fire from American battleships took out the big guns in short order, although one of them maintained an intermittent, if inaccurate, fire throughout D+1. Colonel Shoup stated emphatically that the 2d Marine Division was fully aware of the presence of eight-inch guns on Betio as early as mid-August 1943. By contrast, the division intelligence annex to Shoup’s operation order, updated nine days before the landing, discounts external reports that the main guns were likely to be as large as eight-inch, insisting instead that “they are probably not more than 6-inch.” Prior knowledge notwithstanding, the fact remains that many American officers were unpleasantly surprised to experience major caliber near-misses bracketing the amphibious task force early on D-Day.
Destruction of one of the four Japanese eight-inch Vickers guns on Betio was caused by naval gunfire and air strikes.

Sherman Medium Tanks at Tarawa
One company of M4-A2 Sherman medium tanks was assigned to the 2d Marine Division for Operation Galvanic from the I Marine Amphibious Corps. The 14 tanks deployed from Noumea in early November 1943, on board the new dock landing ship Ashland (LSD 1), joining Task Force 53 enroute to the Gilberts. Each 34-ton, diesel-powered Sherman was operated by a crew of five and featured a gyro-stabilized 75mm gun and three machine guns. Regrettably, the Marines had no opportunity to operate with their new offensive assets until the chaos of D-Day at Betio.
