brigades (3rd, 6th and 12th) and two British brigades, a total of 120 18-pounder guns and 30 4.5-inch howitzers. At Broodeseinde on 4 October 1917, Grimwade had his two brigades plus five British brigades. German counter-battery fire was fierce and the artillery and ammunition columns came under heavy fire. Despite casualties of the same order as the infantry, the gunners managed once again to produce a tremendous barrage, enabling the infantry to advance. In January 1918, Grimwade was promoted to colonel in the Australian Military Forces. In a quiet sector of the line near Messines the 3rd Division, now part of the Australian Corps, spent the winter preparing for a German Offensive in the Spring. Grimwade and John Monash clashed with the new Corps Chief of Staff, Major General Brudenell White, over the placement of the artillery, which they felt was too far forward and would be overrun in the event of an enemy offensive. In the event, the initial German blow fell on the Somme sector to the south and the 3rd Division Artillery was rushed south to defend the river. For the Battle of Amiens on 8 August 1918, Grimwade had control of 9 brigades of field and horse artillery. They fired the initial barrage and then took up defensive artillery positions. The gunners fired in support of the advance to the Hindenburg Line and beyond, and remained in the line after the infantry had been withdrawn, firing in support of the British and American armies. On 14 November 1918, Grimwade became GOCRA of the Australian Corps. In response to a strike by men of the 3rd Division Artillery in January 1919, Grimwade resumed command and listened sympathetically to their troubles, attempted to rectify what he could, and promised to pass the rest on to an equally sympathetic corps commander, Lieutenant General Talbot Hobbs. Grimwade had been made a Companion of the Order of St Michael and St George (CMG) in 1917 and a Companion of the Order of the Bath (CB) in 1918 and had been Mentioned in Despatches four times. He returned to Australia on 27 February 1919. Post war From 1926 to 1930 Grimwade commanded the 4th Division. He died on 2 January 1949.
