He brought me up the road north-east from Wavre. We left the car under dark trees; and he directed me to a hillock on the right. After an age of waiting, little dispersed flashes and reports came from the hollow in the dark in front. The Germans were getting into touch. It was the first time I had heard the mitrailleuse, like the ripping of rough canvas. Answering flash and snarl came from a rough semicircle of shadow in front and on the south side of them. Larger guns came into action on the north, muffled behind slopes. There is little to see by day in a modern battle unless one takes part. Nothing to see at night. I was due back. When I left the commandant, to return through Wavre, the stretchers were passing through empty streets. It was not yet apparent what line the German northern armies were about to adopt for their main advance. The Uhlan screen prevented exact reconnoitring. We were aware that the French troops were coming up; and there seemed to be signs that they intended either to throw across a number of regiments to assist the Belgians east and south of Brussels, or to form a continuous line with the Belgian army on a curve from Diest to Namur. The latter plan would have forced a great battle in the neighbourhood of Genappe, south of Waterloo. At the same time I was aware that the Government were anxious both on account of the small numbers of French crossing the frontier and at the apparent slowness of their advance. We did not know of the strategy that had concentrated the French armies upon Alsace-Lorraine, or, consequently, of the time necessary for the alteration of the balance of troops towards the north. It was rumoured, as it appears now among the Germans also, that the British force would either advance by Brussels, and hold a position in the centre of the defensive loop from the north of Hasselt to the French positions upon the Meuse and Sambre, or cover Antwerp and the Belgian left wing, thus preventing a turning movement of the Germans along the frontier of Dutch Limburg. The position became clearer when the news arrived of the advance of German army corps across the Meuse; and of the great concentration that was proceeding in the neighbourhood of Hasselt. It was still supposed, however, to be largely a movement of cavalry. Heavy fighting was reported on Thursday and Friday at Haelen. Friday was a brilliant sunny day. It was full of surprises. We forced our way along rough lanes, to run suddenly into small reserves or batteries hidden from the aviators under trees. At times we had to move hazardously with one wheel in a ditch, as we passed lines of munition waggons, or crowded along jogging lines of cavalry. We skirted behind the trenches from Louvain to Diest, and thence to Haelen. Haelen, Friday.
