Junior assistant second engineers herbert harvey and Johnathan shepherd were the first victims of the sinking to die. They drowned in boiler room 5 when water broke through a bulkhead separating boiler room 5 and boiler room 6.
it wasnt a bulk head it was the coal bunker, a huge difference. if a bulkhead had failed during the sinking it would not of taken 2:40:13 it would of been minutes
