Why did the Anzacs land at Gallipoli?

Answer 1

They went to help fight the war. It was out of courage, bravery and in some ways, stupidity. So many Australians died in a war that wasn't theirs to fight.

There was a far reaching strategic plan to aid Russia by sending naval convoys through the Bosporus into the Black Sea from the Mediterranean. To do this the Allies would need to secure the land from Turkish artillery bombardment, and the Dardanelles was part of this area to be secured. Unfortunately the Gallipoli landings were not made with sufficient strength or vigour to accomplish this aim. Basically, it is sad to say from an Allied point of view, that the men on the ground were let down by poor generalship & lack of leadership from the powers that were both on site & in command at a distance. A far reaching aim was not impelled to achieve more than the most modest of objectives, that of getting ashore, once there the forces were allowed to be out gunned by the Turkish defenders, leading to many casualties & eventual withdraw.

Answer 2

To help support the British, in fighting the Turk's. They believed they were fighting for her majosty, Australia and god.
