After the Brigade retired from its advanced position, on Sunday the 14th, it formed near the gas-works, on the outskirts of the city. The enemy, from the heights beyond the town, occasionally threw a shot towards our lines, many of which struck the gasometer,--an iron structure,--glanced off with great fury, tearing away pieces of the iron, and throwing them about in various directions.

All during the 15th, the regiment had direct orders to hold itself in readiness to march at a moment’s warning. After dark, the men were directed to roll up their blankets, and were cautioned against lighting their pipes or kindling fires. All orders were passed along the line in low tones. It was apparent that some movement of importance was on foot, and it was soon discovered that our army was falling back across the river, a movement that was attended with great danger, inasmuch as the enemy was close at hand, and the river only passable by means of pontoons. Late in the afternoon, after it was decided to recross the river, the regiment was directed to remain until the other troops of the corps had crossed, when it was to remove three small pontoon bridges that had been thrown across a canal or creek which ran between the Rappahannock and the enemy’s works, and then emptied its waters into the river. The Brigade commander, Colonel Christ, intimated that he considered the undertaking a hazardous one, and scarcely worth the risk. The corps commenced crossing shortly after dark, the regiment remaining in its position until all were fairly across, and then moved forward and a considerable distance to the left, and commenced at once the work assigned to them. A captain, with a sufficient number of men, was detailed for each bridge, and the work went on rapidly and noiselessly, the regiment mean-while remaining in line of battle, ready for any emergency. It was remarkable that a work of this nature could be done so quietly; but the men, as well as the officers, fully realized the necessity of stillness. Only once in the course of the labor was any noise made, and this was caused by the falling of a plank against one of the boats. Even this noise was not great; but it seemed to the anxious listeners like a peal of thunder, that was likely to be followed by the crash of the enemy’s muskets. Fortunately it did not arouse the enemy; but it called out a large bloodhound, with powerful voice, which came running down to the opposite shore of the creek, and commenced baying and howling, keeping up its savage cries till the work was ended, annoying the men greatly, as they suspected that the next yelp would be followed by the enemy’s charging yell. Finally, after what seemed an age, but which in reality was only a short time, the three bridges were all removed, without the loss of a single piece, and the boats successfully floated across the Rappahannock. If the enemy had moved forward,--and it is surprising that they did not,--the result would have been disastrous to the regiment, perhaps cost it its very existence; and had this result followed, the attempt would have been deemed an act of folly. As it was, the plan was successfully carried out, and the regiment was warmly congratulated.
