An attack was planned on the olive oil factory

 Moriarity's company moved along the ridges towards the olive oil factory. Campbell ordered an attack at 10am. The plan was for an artillery bombardment. The attack would be made if the bombardment seemed to be effective. Captain Killey decided "how much ammunition" the could afford to fire. 

While moving forward, Moriarity was shot and killed by a German rifleman. Lt. Savage was wounded while moving forward. Because of those reasons, there was no attack at 10am.

Campbell's next plan was for an attack at 5pm. The attack would be made after an artillery and mortar barrage. They would send some 200 Greeks down one wadi. At the same, about forty Australians would move down another wadi. Once in place the two groups would charge. The rest of Capt. Travers' company, on the heights, would fire on the factory at a range of 100 t0 200 yards. 

The Greek troops did not move when they were supposed to. The Australians ran forward from the wadi. Many were hit. Those not hit sheltered behind a bank some forty yards from the factory. Campbell was near to the Australians, and he told them not to move.
