The 92nd Field Artillery Brigade had been fighting meanwhile with the 30th Division, coming under the orders of the 20th only for a short time on the 23rd of March. At 11 A.M. on that day the brigade marched south to positions of observation to cover the crossings at Libermont and at Ramecourt, a mile and a half further north. Between 3 and 4 P.M. it was decided that guns were wanted just north of Esmery Hallon, so four 18-pdrs. and four howitzers, from A/92 and D/92 Batteries respectively, were pushed forward. By the time these had come into action it was getting dark, and, beyond the fact that the enemy was shelling Esmery Hallon, the situation was obscure. It was a bad bit of country, low-lying, marshy, and full of irrigation cuts, and observation was made difficult by small scattered osier beds. The early morning of the 24th was misty. Under cover of darkness the enemy had worked his way almost up to the rising ground immediately east of Esmery Hallon and on the flank of the guns. With the enemy established on this vantage point, the guns would be cut off. Fortunately Lieut. Patten, M.C., who had been sent to warn the batteries of the situation, fell in with the limbers already on their way up, and pushing on at the gallop succeeded in withdrawing the guns under the nose of the enemy. The guns then crossed the canal and took up their former positions. By this time Esmery Hallon was partially enveloped by the enemy, whose infantry, just north of the village, was engaged by C/92. The French, who had come up during the night, were making a gallant stand opposite the western exits of the village. In order to help them the 92nd Field Artillery Brigade maintained constant fire throughout the day, inflicting heavy casualties on the enemy. Further south the situation was somewhat quieter; Libermont had been occupied by the French and liaison had been established between them and B/92 and D/92 Batteries. At the request of the battalion commander in Libermont these two batteries searched and swept the Bois de l’Hôpital. This wood, lying east and south of Libermont and extending right up to the canal, hid all the movements of the enemy at this point. By dawn on the 25th the enemy had drawn up to the bridge-heads, but all attacks that morning were beaten off with heavy loss. The French had no guns east of Ognolles (one mile south-west of Ercheu), so the 92nd Brigade found itself responsible for the immediate support of the French infantry. B/92 and D/92 were in and near Ercheu, covering Libermont and the crossings in its neighbourhood; A/92 and C/92 were further north, covering the bridge at Ramecourt and the roads from Esmery Hallon. These two latter batteries accounted for a large number of the enemy, who in this area was forced to attack down an exposed slope. Opposite Libermont the problem was very different. It had become increasingly evident that there was no defensive line on the right, where officers’
