A raid on Amman was the next operation for the regiment.
The ANZAC Mounted Division, 60th (London) Division and the Imperial Camel Corps Brigade would all take part.
On 13 March the regiment started back to the Jordan Valley through heavy rain.
Orders for the raid were issued; the brigade would advance on mountain tracks, via the village of Ain Es Sir, then to Amman.
The rains postponed the raid, and it was not until 01:30 on 24 March that the brigade crossed the river Jordan, by a pontoon bridge at Hajlah.
At 09:30 the regiment, the Wellington Mounted Rifles and the 181st (2/6th London) Brigade started clearing the area between the river and the foothills.
The vanguard, formed by the 1st Squadron and the Auckland Mounted Rifles, had by 16:30 left the Wadi Jeria and started up into the hills.
In the wet and cold weather progress was slow.
The narrow tracks meant that all wheeled transport, including artillery and supply wagons, had to be left behind.
They reached Ain Es Sir at 14:00, two hours behind the vanguard.
Out of contact with the division, they remained at the village for the remainder of that day and the next.
Patrols checked the area between the village and Amman, which was around six miles (9.7 km) away.
The remainder of the division, which had travelled by a different route, arrived later that day.
They were in no physical condition to attack, so the advance was postponed until the next day.

The assault began at daylight on 27 March; the 8th Squadron moved across the plain to Kusr, where their progress was stopped by heavy Turkish small arms fire.
The squadron formed a defensive line, while the 1st Squadron moved past them on the right and captured a small hill.
Turkish artillery and machine-gun fire grew heavier all day, and another attempt by the 8th Squadron to move forward at 16:00 also failed.
At 19:25 the Turks counter-attacked the 1st Squadron, but were forced to retire.
That night patrols were sent to reconnoitre the Turkish positions, so they could be more easily attacked the next day.
At dawn on 28 March the entire division tried another attack.
The 1st Squadron managed to capture a small trench, but without their artillery support they were unable to move any further forward in the face of heavy Turkish machine-gun fire.
All that day and night they managed to hold onto what they had won, waiting for reinforcement to continue the attack.

The next day it was decided to make a dismounted attack on Hill 3039, outside Amman.
The regiment, while still holding its own lines, provided eleven officers and 102 other ranks to take part in the assault.
At 02:00 they formed up and started forward, the regiment's contingent forming the second line with the Wellington Mounted Rifles.
The assault was successful, the first line capturing their objectives.
The second line passed through them onto their objectives.
With around three hundred yards (270 m) to go, Turkish machine-guns opened fire on them, but they pressed on, capturing a machine-gun and fourteen prisoners.
Then the 8th Squadron moved forward with the 4th (ANZAC) Battalion, Imperial Camel Corps Brigade, and captured the last Turkish position on the hill.
The brigade settled in to defend the hill, the regiment located between the brigade's other two units.
At dawn Turkish artillery targeted the hill, and at 09:30 the Turks counter-attacked the New Zealanders.
They were stopped by the brigade, using captured machine-guns in addition to their own weapons.
Turkish artillery continued to bombard the hill until 16:00, when another counter-attack began, mostly to the regiment's left; this was driven off.
The third counter-attack came an hour later but was also defeated.
Elsewhere the rest of the division had been trying to reach Amman but could not make any progress.

Unable to continue the attack, and with a shortage of ammunition and rations, the division was ordered to withdraw back to the River Jordan.
The brigade was ordered at 18:00 to retire back to Ain Es Sir.
On arrival the 1st Squadron formed a defensive line, while the rest of the regiment rested.
