The first Australian division to mount a major attack on the Western Front was the 5th Division. The attack, the Battle of Fromelles, was a disaster with the division suffering 5,500 casualties for no gain. The 1st, 2nd and 4th Divisions, combined as I Anzac Corps, fought the Battle of Pozières and subsequent Battle of Mouquet Farm, part of the Battle of the Somme. In Egypt, the light horse had helped repulse the Turkish attempt to capture the Suez Canal in the Battle of Romani.
