At 17:00, Hodgson commanding the mounted screen, asked Chauvel commanding the mounted attack on Gaza, for reinforcements. Chauvel sent back the 8th and 9th Light Horse Regiments (3rd Light Horse Brigade), commanded by Brigadier General J. R. Royston. They moved back quickly under Royston's command to capture a high hill northwest of Hill 405, which enabled the units of the Berkshire Yeomanry (6th Mounted Brigade) to hold their position. The 8th and 9th Light Horse Regiments (3rd Light Horse Brigade) with the 1/1st Queen's Own Dorset Yeomanry (6th Mounted Brigade) held the line, while the 1/1st Nottinghamshire Royal Horse Artillery and the Berkshire Battery enfiladed the advancing hostile formations. Six hostile guns in their firing line, returned fire. When three additional hostile batteries were brought forward, they enfiladed the Berkshire Battery, forcing it to withdraw at about 18:30, just before dusk.
