I have described this period as a comparatively quiet one, but that is not to say that the batteries were left alone by the Boche artillery. Shelling of a desultory sort was always going on, and most of the batteries came in for an occasional bombardment--a _daily_ bombardment it would be more correct to say in the case of the two batteries in Bailleul. Fortunately the shooting was strangely ineffective. D/310, for instance, was heavily shelled on the evening of the 23rd January; but though there were three direct hits on emplacements and the whole position was deeply pitted with shell craters, no damage was done to men or material. A/310 was less fortunate on the 5th February, when, unhappily, two sergeants and a signaller were killed, though no guns were put out of action. B/310 was shelled the same day at Arleux, and on this occasion one officer was wounded, Lieut. C. R. Witcher. On the 16th February the artillery withdrew from the line into billets in and around Aubigny, Caucourt, and Frevin Capelle, the headquarters being in the chateau at Berles. This was the only rest we were to get under the scheme mentioned above. [Sidenote: March, 1918.] On the 6th and 7th March we went into the line in relief of the 31st Division, against an enemy front of about 4000 yards, stretching from Oppy to Acheville; the 310th was again on the right, and the 312th on the left, batteries being mostly in or about Willerval and Farbus. Headquarters were at Roclincourt. It now seemed certain that a big German offensive was brewing, and henceforth practically all our firing was done by detached sections, while the main positions remained silent, and every possible artifice was employed to conceal them from detection by the enemy. At the same time several single guns were distributed along the front for defence against tanks, being so sited that every possible approach by a hostile tank would be under fire from one or more of the guns. Some experimental firing by single guns was carried out on the afternoon of the 10th March near Souchez. A dummy tank, about three-quarters real size, was drawn across an open space at about a thousand yards from the gun. Detachments from various divisions engaged it in turn, and the results were most reassuring, two or three direct hits being very quickly scored in nearly every case; it seemed to prove that an anti-tank gun well handled ought to be able to knock out several tanks in a minute or two.
