At 15:30 on 21 August the Battle for Hill 60 began.
Charging straight at the hill, the regiment suffered sixty per cent casualties, among them Hutton in command.
He was replaced by Major Hurst, from the 1st Squadron, and they succeeded in capturing the Turkish trench within fifteen minutes of going over the top.
But on either side of them the rest of the attack had failed, leaving the regiment and the Otago Mounted Rifles isolated from the rest of the force.
Not having the manpower to continue the assault, they were ordered to dig in and hold the position.
They held on until 23 August when they were relieved by the Auckland and Wellington Mounted Rifles.

Three days later the regiment returned to their previous position to continue the assault.
The attack began at 17:00 on 27 August with the regiment leading the brigade.
They charged across the sixty yards (55 m) of open ground and into the first Turkish trench.
Within minutes they were up and on their way again, and captured the second and third trenches, which they defended all night and through the next day.
Casualties had been high; from the 119 men who had started the assault there were now only eighteen left, commanded by the only officer, Captain Gibbs.
The brigade's other regiments were in a similar state, but they remained in the trenches until they were relieved after dark on 29 August.
