 Around 04 : 30 Turkish <unk> opened fire on the boats , but the first ANZAC troops were already ashore at Beach Z , called Ari Burnu at the time , but later known as Anzac Cove . ( It was formally renamed Anzac Cove by the Turkish government in 1985 . ) They were one mile ( 1 @.@ 6 km ) further north than intended , and instead of an open beach they were faced with steep cliffs and ridges up to around three hundred feet ( 91 m ) in height . However , the mistake had put them ashore at a relatively undefended area ; at Gaba Tepe further south where they had planned to land , there was a strong @-@ point , with an artillery battery close by equipped with two 15 cm and two 12 cm guns , and the 5th Company , 27th Infantry Regiment was positioned to counter @-@ attack any landing at that more southern point . The hills surrounding the <unk> where the ANZACs landed made the beach safe from direct fire Turkish artillery . Fifteen minutes after the landing , the Royal Navy began firing at targets in the hills .
