They say history is written by the victor. I was lucky in 2014 to get Churchill's The World Crisis, all 5 volumes, on Kindle for very little money. His analysis of the Gallipoli campaign naturally blamed the Admirals and Generals.
In essence the Navy was slow to land troops, ships were not combat loaded for an invasion. The Army was slow to exploit their bridgehead etc. Indeed he might well have been correct but in essence there was no unified command, an organisation that only evolved slowly in WW2.
