After supper we passed through Fleurines, Pont Ste. Maxence, and Blincourt to Estrées-St. Denis, where we spent the night. Along this road had recently passed a great German army, and their engineers had constructed new roads to the right and left of the original one, so that their regiments had been able to march steadily three abreast, probably no small factor in their successful retreat. * * * * * This morning we got under way at half-past six. The day was hazy, threatening rain; mists rising from the ground made it impossible to see clearly for any great distance. The heavy atmosphere muffled the sound of guns so that it was difficult to judge their location even when we were fairly close upon them. The day was, however, a most advantageous one on which to move about near the front, provided one were careful to ascertain where, off in the mist, the enemy's batteries lay. We first reached the front at Roye-sur-Matz, which we found was occupied by a French colonial brigade. This place is about three miles from Lassigny, which is far within the German lines, and from which they have recently organized heavy attacks against the French forces. In Roye-sur-Matz the German shells were bursting, punctuated by the muffled slump of falling walls. The place had been deserted by its inhabitants, but Turcos and black Senegalese wandered about the ruined streets indifferent to the shell fire. For a week past there has been heavy fighting in the vicinity of Roye and Lassigny, probably the heaviest that has taken place in the Battle of the Aisne since the latter part of September. We drove slowly down the main street of the village looking for an officer who could tell us about the local geography. We finally met the acting brigadier, a French colonel, who informed us that it was not safe for us to continue more than a block farther in the direction in which we were going, as the far end of the village was "between the lines" and we would there come under the observation of the German sharpshooters. This officer said that the best way to follow the battle-line would be to turn back through the village and take the first road to the right.
