Rid of all encumbrances, we trotted merrily on whenever the road permitted, and, arriving at Castre (an old Roman legionary station), found there the 23d Light Dragoons just turning out, having also received orders to march upon Enghien. A Captain Dance, with whom I rode a short distance, told me he had been at the ball at Brussels last night, and that, when he left the room, the report was that Blucher had been attacked in the morning, but that he had repulsed the enemy with great slaughter, was following up the blow, and that our advance was to support him. The road for the last few miles had been upon a more elevated country, not so wooded--a sort of plateau, consequently hard and dry; but immediately on passing Castre, we came to a piece which appeared almost impassable for about a hundred yards--a perfect black bog, across which a corduroy road had been made, but not kept in repair, consequently the logs, having decayed, left immense gaps. The 23d floundered through this with difficulty, and left us behind. How we got through with our 9-pounders, the horses slipping up to the shoulders between the logs every minute, I know not; but through we did get, and without accident, but it took time to do so. About noon, after threading our way through more mud and many watery lanes, doubtful if we were in the right direction, we came out upon a more open and dry country close to a park, which, upon inquiry, proved to be that of Enghien. To the same point various columns of cavalry were converging, and under the park wall we found Sir Ormsby Vandeleur’s brigade of light dragoons, dismounted and feeding their horses. Here we also dismounted to await the arrival of Major M‘Donald; and as I looked upon the day’s march as finished, deferred feeding until our bivouac should be established--another folly, for an officer in campaign should never lose an opportunity of feeding, watering, or resting his horses, &c. Attracted by the novelty of the scene and the fineness of the day, we had numerous gay visitors here--ladies and gentlemen--who had stationed themselves within the park, enhancing by their presence the gaiety of the scene, for we had halted immediately under the park wall, and at the point where the road to Braine le Comte by Steenkerke branched off from the one we were on. All the corps as they arrived, I observed, took this road, and continued onwards, which made me somewhat impatient lest I should have halted short of my destination. Having waited a good half-hour, and no Major M‘Donald appearing, I began to look about for some one who could give me information, but no staff-officer was to be seen, and no one else knew anything about the matter. Corps after corps arrived and passed on, generally without even halting, yet all professing ignorance of their destination. Pleasant situation this! Sir Ormsby’s dragoons were by this time bridling up their horses and rolling up their nosebags, evidently with the intention of moving off. Seeing
