For the next attack, the Battle of the Selle, IX Corps HQ selected important localities to be bombarded by 70th Siege Bty's heavy howitzers, for which 200 rounds of ammunition per gun were accumulated. The corps attacked on 17 October, 'lifted forward' by two great belts of intense artillery fire, and a German counter-attack was hit by every gun within range. IX Corps renewed its advance on 23 October, with 12th Bde part of a massive corps artillery reserve. The attack went in at 01.20 in moonlight, after the heavy guns had done the usual CB and harassing fire bombardments, and the results were extremely satisfactory. After a pause to regroup and reconnoitre, IX Corps stormed across the Sambre–Oise Canal on 4 November (the Battle of the Sambre). After that the campaign became a pursuit of a beaten enemy, in which the slow-moving siege guns could play no part. The war ended with the Armistice with Germany on 11 November. 70th Siege Battery was disbanded in 1919.
