Landings were made on the Asiatic side of the straits by the French as a feint; at Bulair a proposed feint by the Royal Naval Division did not go ahead...exactly. i am not entirely sure why this decision was made but then Lt Freyberg volunteered to land with a small force and create a distraction using 'firepots'. even given the fog of war i do not see how this could possibly have worked but apparently it did and the defending division remained in place for some time. the ANZACs went ashore as described below but, and here we get a bit sensitive, owing to inexperience and poor direction from all levels the assault did not reach the objectives outlined and were then forced backwards by counter attacking Turks. depending on your view of the Turkish military and when it appeared on the scene, on whether the untried ANZACS were able to follow a screening order, and whether as senior officer ashore Sinclair- McLagan had the right to alter the plan, his decision to stop either saved the landing or doomed the campaign. either way the initial landings were opposed by one artillery piece, one or two machine guns, and two platoons of riflemen spread along several miles of coast.
the british landings at the foot of the peninsular- Cape Helles- which seem to be the ones you are referring to- were on five beaches and at varying strengths and defended by varying forces. the landing at Y beach was initially unopposed but as the assault force moved inland it incurred heavy casualties and was forced to withdraw. X and S beach were opposed landings similar to the ANZAC landings, S forces beat off several counter attacks whilst X forces were able to widen their lodgement and take pressure off the other beaches.
these were W (Lancashire Landing) and V. W was heavily opposed with the defences you described, but the right most line of boats were caught by a swell and landed one company in the wrong place- though it proved perfect for outflanking the Turks and ejecting them from the defences. Nevertheless the attacking Lancashire Fusiliers had taken heavy losses and the follow on forces were required to aid in clearing the beach and establishing a beachhead instead of following through to attack in depth and link up with the other beaches.
at V beach it was decided that in order to overcome the defences that a crude infantry landing ship would be constructed out of the mv River Clyde, from which 2000 men were expected to go ashore in one rush, supported by a battalion to be landed, as elsewhwere, in ship's boats. in the event the Clyde landed too far out and after an epic struggle by its crew to keep lighters in place to facilitate the landing, it was discovered that not enough troops could exit the doors of the vessel and rush for shore to beat the fire of the machine guns. similarly the open boats were treated to heavy machine gun fire and several foundered with all in them shot. throughout the day attempts were made to leave the Clyde but it was not until troops advancing from W beach forced the Turks to abandon the defence was V Beach secured.
many men were awarded the Victoria Cross though my references to exactly how many is not at hand. i think it was 6 at W beach and 5 at V beach. those awarded at W beach were selected by ballot from amongst the surviving soldiers of the Lancashires- to my knowledge the only time the award has been given in such circumstances.
