U-Go was launched in March, with the aim of cutting off 17th Indian Division. The decision to withdraw the division from Tiddim came too late, and although it successfully disengaged from Kennedy Peak it was cut off by a series of roadblocks. On 15 March it was stopped at the Taitum Saddle. Lieutenant-Colonel Younger organised a fireplan with 393 Bty firing from the north and 311 and 312 from the south, which gave the Japanese no reverse slope for protection. The first attack on the block failed, but next day, reinforced by mountain and anti-tank guns, and one 25-pounder firing directly into enemy bunkers, the position was taken on 16 March and the following day the regiment provided Defensive Fire (DF) tasks to prevent it being recaptured. Suffering heavy casualties from the artillery fire, the Japanese suddenly fell back and opened the way to the bridge over the Manipur River. For the final stage of the retreat the division had to clear a block and recapture a supply dump at Milestone 109. A first attack on 22 March failed, but the following day with 311 and 312 Btys firing in support the enemy aa driven of the positions. The regiment's Forward Observation Officers (FOOs) were able to range their guns onto the objective when their own advancing infantry were only away from it. By now ammunition was down to five rounds per gun (the regiment had fired 6900 in three weeks), and attempts to air-drop supplies had failed, but on 4 April the regiment marched into Imphal where it met 5th Indian Division, which had been flown in.
