The casualties in May were comparatively light. 2/Lieut. H. M. Bradley and 1 man were killed by the falling in of the dugout they were occupying, and in addition 2 men were killed and 12 wounded.

At the beginning of June the 2/4th Battalion moved back to Contay in Divisional reserve, and resumed its counter-attack duties. Here a severe loss was sustained in Lieut.-Col. W. R. H. Dann, D.S.O., who was appointed to command the 60th Infantry Brigade with the temporary rank of Brigadier-General. Lieut.-Col. Dann had been in continuous command of the 2/4th Londons since November 1916, and during the Battalion's seventeen months of active service he had held the confidence and affection of all ranks. His great skill as a commander, his imperturbable coolness in action, his unfailing care for the welfare of his men, had endeared him to all, and the Battalion said good-bye to him with genuine sorrow. The command was taken temporarily by Major Tollworthy, but on the 8th June Major Grover, D.S.O., M.C., who had been hit at Cachy, rejoined and assumed command with the acting rank of Lieut.-Col.

On the 5th June the Battalion moved to tents and shelters at Mirvaux, where attempts were made to carry out a few days' training. Standing crops, which might on no account be damaged, interfered sadly, and but little was accomplished. The plaint of the Divisional Staff made at the time is rather pathetic: "Training areas have not yet been allotted. As is usually the case the hiring of these is a very lengthy procedure, and is not likely to be completed before the Division leaves the area." Apparently even the full tide of the German offensive had beat in vain against the massive structure of regulations.

The end of May had witnessed the recrudescence of fighting on the French front on the Chemin des Dames. Once again the weight of the enemy's assault had overtaxed our Allies' resources in defence, and by the 4th June the Germans had reached their 1914 line on the Marne at Chateau-Thierry, and were threatening Paris. It was firmly anticipated that this fresh German success would mean another blow against the British front at its junction with the French, and to meet this new menace the XXII Corps was reconstituted under Sir A. J. Godley, in G.H.Q. reserve. To this new formation were posted the 12th, 37th and 58th Divisions, the whole of which were held in readiness to move at two hours' notice. In accordance with this scheme the 173rd Brigade was moved to the Amiens area, the 2/4th Londons being billeted—this time in comfortable quarters—at Guignemicourt on the 10th June.

The German attack between Montdidier and Noyon did in fact develop, and the 37th Division was moved southwards. The 58th Division was, however, not called upon, and, the danger being passed, returned to the line after a week, the 2/4th Battalion moving on the 17th June to Molliens au Bois.

For the remainder of June and the whole of July the 2/4th Battalion remained in forward areas. At first the 173rd Brigade was in line astride the Amiens-Albert Road and the Battalion successively occupied positions in reserve in the La Houssoye line, in support in the Dodo-Hill-Darling system, and in front trenches in the Ethel-Dandy system.

The work on defences and the patrolling activity of the previous month were here continued without abatement, but with very little incident of interest. During the last week of June the weather, which had been uniformly good, was broken by some heavy showers, which at once developed the extraordinary propensity of French mud for turning into glue on the least provocation. This hampered work on the defences but had no effect on the spirit of the Battalion, which with careful training was now developing once more into a well-knit and disciplined fighting unit full of good cheer and confidence.

On the 25th June Capt. F. W. Walker, D.S.O., who had been wounded at Cachy, rejoined and resumed his duties as Adjutant.
