July 19th and 20th.–Nothing worthy of especial mention the last two days; reports say the rebels are seventy thousand strong, with ten thousand additional men near at hand, strongly posted behind the run, with all commanding points well fortified. We have made many reconnoisances and find the enemy’s position in front and left too strong for direct attack and so the plan now is to move the bulk of the army, under cover of the thick woods, to the right, and attack in earnest; in the mean time, making demonstrations directly in front, and on the left, with force enough to take advantage of any weakness that may be discovered. All the preliminary arrangements are made, and we are entirely prepared. Saturday night taps sounded as usual at nine o’clock and we all tucked ourselves under the blankets and lay down for a good night’s sleep; we had hardly got comfortably fixed, when we were ordered to get up and fall in silently. We got up wondering what was the occasion of this nocturnal disturbance, but quietly rolled and slung our blankets, fell into line, and answered to the roll call. We were ready to start by twelve o’clock but those ahead of us did not get out of our way till nearly two o’clock, so we sat down in the ranks and waited our turn. It was a brilliant moonlight night, and we could see the long line of flashing bayonets filing off to the right, looking like an immense silver sea serpent. From Centreville to Fairfax court house, all the troops were in motion, and where an hour before everything was quiet and still, now the ground trembled with the tramp of armed men, and innumerable horses. We stepped out promptly at last, glad to be in motion,; taking the Warrington road through Centreville, we marched some distance, then turned off to the northward, on a wood road, and were hid from view by the dark, gloomy shadows of a pine forest. Everyone knew the object of the movement, and was anxious to get well in rear of the rebel left before daylight, and take him by surprise. For nearly three hours, our march lay through the dark pines; finally about break of day, we emerged into open fields, and saw away off to the front and right the Bull Run and Blue Ridge mountains, with pleasant fields, and shady woods, laying quietly at their feet. It was so still and peaceful that it was hard to believe this beautiful Sunday morning we were going to fight a battle.
We halted now awhile, giving the stragglers a chance to come up, and all of us a much needed rest, as we were very much fatigued, besides being hungry, and longed to make some coffee, but the orders were imperative, no fires! no noise! very shortly, several shots were fired directly in our front, the bugles sounded the assembly and we fell in; the First and Second Rhode Island regiments were deployed in line of battle, and with a regiment of regular cavalry out as flankers, and several companies of infantry deployed as skirmishers in front advanced in the direction of the firing, we following in column, well closed up, a short distance in rear, a battery moving immediately in our front. The stately and well ordered advance to our first battle was most impressive. Not a word was spoken, every man busy with his own emotions and trying to do his duty.
