to be rotated. After the battle ended, 2/1st Lowland Hvy Bty was rested from 18 December. On 5 January 1918, 2/1st Lowland Hvy Bty joined the mixed-calibre 93rd HAG (93rd (Mixed) Brigade, RGA, from 1 February), and remained with this brigade for the rest of the war. 93rd Brigade was at the time with Fourth Army, but on 14 March it transferred to Fifth Army, just in time to be caught up in the Spring Offensive and Great Retreat. 93rd Brigade moved to Fourth Army for the Battle of Amiens on 8 August 1918, supporting the Australian Corps in a barrage that was so thick and accurate that all the Australians' Phase 1 objectives were secured by 07.00, and scarcely a German shell fell after 05.40. The Australians continued to advance rapidly, sometimes running into their own barrage in their eagerness. The advance continued in a succession of bounds through the Hundred Days Offensive. By early October the Australians were taken out of the line for rest, handing their artillery including 93rd Bde over to the II US Corps for the Battle of Cambrai, in which the Americans advanced up to the River Selle. By the time of the Battle of the Selle (see above), II US Corps was about to be withdrawn for rest, and 93rd Bde was assigned to IX Corps' Reserve. The heavy batteries were well forward so that they could shell the Germans' lines of retreat across the Sambre. 93rd Brigade was part of the massive artillery support for IX Corps' attack on 23 October. After the Battle of the Sambre, the campaign continued as a pursuit until the Armistice, in which the heavy artillery could only play a limited part. When the BEF demobilised in 1919, the battery was disbanded. Interwar When the TF was reconstituted as the Territorial Army in 1920–1, the Lowland (City of Edinburgh) Hvy Bty formed the basis of a new 2nd (Lowland) Medium Brigade, RGA, quickly renumbered as the 57th (Lowland) Medium Brigade, RGA. It consisted of one battery derived from the Lowland (City of Edinburgh) Hvy Bty, the others being converted from the 6th and 8th Battalions of the Royal Scots: HQ at 6 Wemyss Place, Edinburgh 225th (City of Edinburgh) Medium Bty at Drill Hall, 124 McDonald Road, Edinburgh – from Lowland Hy Bty, RGA 226th (City of Edinburgh) Medium Bty (Howitzers) at Drill Hall, Dalmeny Street, Leith
