One source gives Allied casualties, including deaths from drowning and accident, as about 265,000, of whom some 46,000 were killed in action or died of wounds or disease.
Dr. Bean (Historian) gives Anzac casualties as: Australian 26,094 (7594 killed), New Zealand 7571 (2431 killed). The Australian War Memorial at Canberra gives the Australian casualties as 8709 killed and 19,000 wounded.
The New Zealand official figures given with their World War I statistics issued in 1932 also show a higher proportion of killed, 2721, and a total casualty figure of 7247.
Dr. Bean, whose research was most carefully carried out, gives the total British loss as 119,696 (43,000 killed) and the French as 27,004 (8000 killed).
The greatest visible loss (and to morale, too) was the sinking of six battleships, one French and five British: on March 18, mined during the attempt to force the Straits, Bouvet (French) HMS Ocean and Irresistible; on the night of May 12/13, torpedoed in Morto Bay, near Helles, HMS Goliath; on May 25, torpedoed off Gaba Tepe, near Anzac, HMS Triumph; and on May 27, torpedoed off Helles,
HMS Majestic.
