The infantry had a hard time keeping up. Marches of twenty-five miles in the course of a day were by no means exceptional, and that over the most atrocious roads.
A vivid picture which remains of these weeks is the great clouds of yellow dust kicked up by the Russian columns attempting to retreat and by our infantry hastening in pursuit.
The heat was tremendous, though interspersed with sudden showers which quickly turned the roads to mud before the sun reappeared and as quickly baked them into crumbling clay once again.
