The Battle of Gallipoli was a watershed moment in the history of warfare. Few other battles were initiated with such high strategic hopes that were then dashed so quickly. Its influence carried far beyond the war in which it occurred. Simultaneously, it spurred some observers to proclaim that the amphibious assault was impossible and others, notably then-Captain Earl “Pete” Ellis of the United States Marine Corps, to completely reexamine the amphibious assault in a modern context and design modern forces to accomplish it.
