The weather all through that month of May 1915 was ideal, and nothing could have looked more beautiful than the long, straight white roads, with their line of tall trees on either side that characterize the Routes Nationales and Routes de Grande Communication, the main arteries leading across the borders of France into Belgium, and which run through miles of intensely cultivated land. The main road from Hazebrouck to Ypres is a typical example of the highways of Flanders; with its strip of raised _pavé_ in the centre, it is flanked by earth on either side and runs between an avenue of tall and stately poplars. It has been followed by troops from every part of the world over which flies the Union Jack or the Tricolour, and they have marched along it on their way to fight the bloodiest battles of the world’s history. The nearer one gets to the trenches, the worse becomes the condition of the roads, and that leading through Poperinghe to Ypres was among the roughest on which I have ever travelled. Leaving Hazebrouck, it gradually became worse and worse as one approached and crossed the frontier of Belgium. The _pavé_ in the centre is narrow and has a high camber. The earth that borders it on either side is soft, so that it is particularly difficult for two heavy motor-lorries proceeding in opposite directions to pass one another. It is to the credit of British motor-car manufacturers that the lorries and cars with the Expeditionary Force in France have stood up so well on roads such as they were never designed or intended to travel on.
