This small affair of Boitron Wood was the Irish Guards’ share of the immense mixed Battle of the Marne, now raging along all the front. Its result and the capture of the machine-guns cheered them a little.
The next five days--September 9 to 13--had nothing but tedious marching and more tedious halts and checks, due to the congestion of traffic and the chaos in the villages that had been entered, sacked, defiled and abandoned by the enemy. The Marne was crossed on the 9th at Charly, where--the inhabitants said that the Germans detailed for the job had been too drunk to effect it--a bridge had been left ready for demolition, but intact, and by this means the First and Second Divisions crossed the river. The weather turned wet, with heavy showers; greatcoats had been lost or thrown aside all along the line of retreat; billets and bivouacs made filthy by the retreating Germans; and there was general discomfort, enlivened with continuous cannonading from the front and the appearance of German prisoners gathered in by our cavalry ahead. And thus, from the Marne the Battalion came by way of Trenel, Villers-sur-Marne, Cointicourt, Oulchy-le-Château, Courcelles and St. Mard to the high banks of the Aisne, which they crossed by the pontoon bridge at Pont d’Arcy on the morning of September 14 and advanced to Soupir in the hollows under the steep wooded hills.
That day, the 2nd Grenadiers formed the advance-guard of the Brigade, followed by the 3rd Coldstream, the Irish Guards, and the 2nd Coldstream. After they had cleared Soupir village, the force was shelled and an attack was made by the 3rd Coldstream, the Irish Guards in support, on a steep ridge near La Cour de Soupir farm, which stood on the crest of the bluff above the river. The heavily wooded country was alive with musketry and machine-gun fire, and the distances were obscured by mist and heavy rain. The 3rd Coldstream, attacking the farm, found themselves outflanked from a ridge on their right, which was then attempted by three companies of the Irish Guards. They reached to within a couple of hundred yards of a wood cut up by rides, down which, as well as from the trenches, heavy rifle-fire was directed. Here Captain J. N. Guthrie (No. 2 Company) was wounded and Captain H. Hamilton Berners killed, while Lieutenant Watson, R.A.M.C., was shot and wounded at close quarters attending a wounded man. Here, too, the Battalion had its first experience of the German use of the white flag; for Lieutenant J. S. FitzGerald with No. 8 Platoon and a party of Coldstream under Lieutenant Cotterel-Dormer found some hundred and fifty Germans sitting round haystacks and waving white flags. They went forward to take their surrender and were met by a heavy fire at thirty yards’ range, which forced them to fall back. Lieutenant E. B. Greer, machine-gun officer, now brought up his two machine-guns, but was heavily fired at from cover, had all of one gun-team killed or wounded and, for the while, lost one gun. He reorganized the other gun-team, and called for volunteers from the Company nearest him to recover it. After dark Corporal Sheridan and Private Carney of No. 3 Company and Private Harrington, a machine-gunner of No. 1 Company, went out with him and the gun was brought in. A further advance was made in the afternoon to the edge of the wood in order to clear out the snipers who held it and commanded the cultivated fields outside. Towards dusk, Captain Lord Guernsey, who was Acting Quartermaster, reported himself to the C.O., who posted him to No. 2 Company, then engaged in clearing out the snipers, in place of Captain Guthrie, who had been wounded. He went forward to assist Captain Lord Arthur Hay in command, and both were immediately shot dead.
