Would all deaths at sea result in burials at sea or would the bodies be returned home for burial. I imagine that high ranking officers may have been attributed a home burial where possible but for the ordinary men including soldiers who dies aboard hospital ships
Occasionally, if the death occurred very close to the final landing, the bodies would be brought ashore. I think there were two Canadians who died at sea and were landed in Canada, perhaps QSAMIKE can confirm? There's a burial in Surrey of a man who died at sea that I can think of off the top of my head.

Gunn, who left Oundle [Northamptonshire] to join the Bucks Imperial Yeomanry for service in the Transvaal, was invalided home from enteric fever, but just before reaching Gravesend, on Saturday, a relapse set in and he succumbed."
