All day I had followed at the heels of a pursuing army engaged on one of the finest battles that ever camp of exercise beheld. Thirty thousand troops had by the wisdom of the Government of India been turned loose over a few thousand square miles of country to practice in peace what they would never attempt in war. Consequently cavalry charged unshaken infantry at the trot. Infantry captured artillery by frontal attacks delivered in line of quarter columns, and mounted infantry skirmished up to the wheels of an armored train which carried nothing more deadly than a twenty-five pounder Armstrong, two Nordenfeldts, and a few score volunteers all cased in three-eighths-inch boiler-plate. Yet it was a very lifelike camp. Operations did not cease at sundown; nobody knew the country and nobody spared man or horse. There was unending cavalry scouting and almost unending forced work over broken ground. The Army of the South had finally pierced the centre of the Army of the North, and was pouring through the gap hot-foot to capture a city of strategic importance.
