51st (H) Division then took part in the pursuit to El Agheila and Tripoli in January 1943. 491 Field Bty claimed that four of its guns were the first Eighth Army guns in the deserted city, having used all of the regiment's available petrol to get there. The regiment took part in the victory parade in the city. By 25 February it was past Medenine in Tunisia and facing the Mareth Line. The Axis force made a spoiling attack on 6 March (the Battle of Medenine) but there was plenty of warning and the advance was easily repulsed. 51st (H) Division had already moved most of its artillery south in waiting for the attack, leaving three Troops to move and fire between various positions to simulate the whole divisional artillery remaining in its old positions. 127th Fd Rgt fired one full regimental task against a group of Axis infantry but was otherwise hardly engaged. Thereafter it was on harassing fire (HF) tasks.
