Gill's account of the battle between HMAS "Sydney" and the German auxiliary cruiser "Kormoran" in November 1941 has been criticised by some authors who view it as being part of an official cover-up, but Gill reached his conclusions independently and without censorship and his account of the battle is generally considered to have been as accurate as possible given that little evidence was available on the events that led to "Sydney" being sunk with the loss of her entire crew. Naval historian and Anglican Bishop to the Australian Defence Force Tom Frame has argued that while Gill "was a man of integrity" and not influenced by the Navy, his account of the battle is "bad history" as it is contradictory and "went beyond the reliable and corroborated evidence which was available to him".
