Shortly before this relief Lieut.-Colonel L. M. Dyson, who had commanded the 255th Brigade, R.F.A., for some years, very reluctantly gave up command of his brigade, ill-health and two severe wounds compelling him to do so. He may be said to represent the best type of modern gunner lieut.-colonel. Always willing, cheerful, and untiring, he was the best possible companion to the infantry brigade with which he worked. At the same time, he kept well abreast of modern developments in artillery. It is difficult to estimate the debt the Division owed to colonels like Dyson, Dawson, and Rorie. This latest move was due to a request from Marshal Foch that four British Divisions might be transferred, two of them to areas south of the Somme, and two to positions astride that river, so as to ensure the connection between the French and British armies about Amiens, and to enable him to move four French Divisions farther east to his right flank. On 13th July Sir Douglas Haig received a further request from Marshal Foch that these four British Divisions might be placed unreservedly at his disposal. This request was agreed to, and accordingly the 15th, 34th, 51st, and 62nd British Divisions were formed into the XXIInd Corps under the command of Lieut.-General Sir A. Godley, and were ordered to move down to the French front. The entire Division moved to the new scene of operations by train, the intended destination being the Chalons-sur-Marne area. It was estimated that the journey _viâ_ the southern outskirts of Paris would take thirty hours. The trains, of which thirty-four were employed, steamed off at intervals of one hour, the first leaving Bryas at 5 P.M. on 14th July, the last train, carrying the Divisional artillery, leaving Pernes at 3 A.M. on 16th July. Before the first troops had reached their destination the Germans, on the morning of the 14th July, launched an offensive on a front of eighty kilometres east and south-west of Rheims, which carried them across the Marne, but which was finally held by the French, American, and Italian forces on this front. This attack was in the first instance checked east and north of Rheims, but as it was making progress westwards along the valley of the Marne towards Epernay and towards the Montagne de Rheims, the destination of the Division was altered, and on the evening of the 15th the first of the Divisional units were detraining in the Nogent-sur-Seine area. As each unit arrived on the 16th it was moved by motor lorry towards the south bank of the Marne in the Epernay area, the manner in which this move was organised by the French being admirable and few delays occurring.
