Bill Murray posed an interesting question in another
thread regarding Frank Fletcher's decision to stop and refuel the Wake Island relief force enroute to Wake.
Bill's comments made me wonder whether the effort to reinforce Wake Island would have been sufficient to allow the US to hold Wake had the US reinforcements arrived at Wake before the Japanese returned.
I recently saw the first-rate documentary
Wake Island: Alamo of the Pacific on the History Channel. According to the documentary, the relief force included another 400 Marines and one squadron of fighters for the airstrip on Wake.
The Marines on Wake could have held out longer than they did since they were ordered to surrender at a time when they had the upper hand in the fighting on the atoll, but the Marine veterans interviewed in the documentary all agreed they they could not have held out indefinitely.
The additional 400 Marines and the fighter squadron, along with extra supplies and ammunition, would certainly have allowed Wake Island, which is closer to Japan than it is to Pearl Harbor, to have held out longer. The limited number of reinforcements would not have been enough to have made Wake Island impregnable given its location, however.
