"The British Burma Star Association seems to lend credence to the swamp attack stories but appears to draw a distinction between the 20 Japanese survivors of one attack and the 1,000 Japanese who were left to fend for themselves in the swamp.[3]. Furthermore there is no corroboration of the event by British military reports or by interviewed Japanese soldiers and local Burmese.[4] These figures are disputed and the event has been described as an urban myth by British historian Frank McLynn, who opined that only a few wounded Japanese had been consumed, although he did admit that the saltwater crocodiles of the region were both "known man-eaters and opportunistic killers".[4] McLynn's criticisms of the account primarily stem from his personal incredulity that the "Japanese firepower, which tore such holes in British tanks and armour" would be incapable of dispatching large numbers of crocodiles at night. His suspicions are not cited to any other source, nor are they echoed by other historians. Additionally, although McLynn accused Bruce Wright's existence of being "unverified", his career in the Royal Canadian Navy and subsequently as a scientist and author is described in many additional sources and McLynn's doubts are again notably not echoed by other historians in this area."
