‘I much regret,’ wrote Sir John French in the same Despatch, ‘that during the period under report the fighting has been characterized on the enemy’s side by a cynical and barbarous disregard of the well-known usages of civilized war and a flagrant defiance of the Hague Convention. All the scientific resources of Germany have, apparently, been brought into play to produce a gas of so virulent and poisonous a nature that any human being brought into contact with it is first paralysed and then meets with a lingering and agonizing death.’ The first such gas attack was launched at Ypres, on Thursday, April 22nd. On the previous Thursday night (the 15th), we left a West Yorkshire Battalion spending its first night in France at a Rest Camp, near Boulogne. So the 49th went to the war on the eve of the Second Battle of Ypres, at a time of an outrage of gas and a shortage of shells. They went in eighty-four trains and on five days between April 12th and 16th, embarking at Southampton Docks, Avonmouth and Folkestone for Havre, Rouen and Boulogne respectively, and they joined the 4th Corps of the 1st Army, commanded by Lieut.-General Sir Henry Rawlinson. Corps Headquarters were posted at Merville, and there the Divisional Commander reported with five of his Staff Officers, and established, as we saw[28], Divisional Headquarters in the mayor’s house, 40 rue des Capucines. On April 18th, the following message was received from His Majesty the King: ‘I much regret not to have been able to inspect the Division under your Command before its departure to the Front. Please convey to all ranks my best wishes for success, and tell them that I shall follow with pride the progress of the West Riding Division.’ A loyal reply was dispatched by General Baldock, and on the same day parties of Officers and N.C.O.’s, followed on the 19th by complete platoons, from the Battalions of the 2nd and 3rd West Riding (147th and 148th) Infantry Brigades were attached to units of the 23rd and 25th Brigades, 8th Division, for instructional duty in the trenches. On the 22nd, the 1st (146th) Brigade moved from Merville to Estaires, and was attached to the 7th Division, and placed under their orders. Sir Douglas Haig visited units of the Division on the following day. Divisional Headquarters were moved on the 27th to two houses and a farm in Bac St. Maur, and at 6 a.m. on the 28th, the Division took over a front of its own at Fleurbaix, covering sections 3, 4, 5 and 6 of the IV Corps sector.
