The old, dismantled ships “Delaware” and “Columbus” were sunk, and several of the vessels that were fired had also been scuttled. The “Merrimack,” having sunk before the flames did her much damage, was, as is well known to our readers, afterwards raised by the Confederates, and constructed into a shot-proof steam-battery.

The total value of these vessels, as estimated by the Chief of the Bureau of Construction, was $1,980,000, while the total value of all the public property lost by this catastrophe is estimated at $9,700,181.93; and the report of Commander Alden to the Secretary of the Navy shows, that, by a wiser and more vigorous action on the part of the commandant of the yard, a large portion of this dreadful loss might have been prevented.

The “Pawnee” reached Fortress Monroe at six o’clock Sunday morning (April 21), having in tow the sloop-of-war “Cumberland,” now so famous in the annals of naval warfare.

The men of the Third Regiment had a severe experience on this expedition, having toiled nearly all night, and been eighteen hours without food. Their introduction to one of the most dreadful experiences of war was indeed a very sudden one, and this was followed by nearly three weeks of privation, caused by the scanty supply of food at the fortress, and by three months of almost ceaseless toil.

Included in the plot of the enemy to capture Norfolk, was also the scheme to capture Fortress Monroe.

At this time an irregular body of Confederate militia, variously estimated as to number, occupied the village of Hampton, about two and a half miles from the fortress, while their pickets held a drawbridge over Mill Creek, not more than a mile distant. The flags of the insurgents could be distinguished at the fortress, flying from the roofs of private and public buildings in Hampton. On the 13th of May, Colonel Dimick made an advance with a body of infantry and a piece of artillery, and forced the enemy from his position at the bridge. The bridge was thereupon occupied by the Federals; but no attempt was made to pursue the enemy beyond this point.

This condition of affairs continued till May 23, when, the garrison having been materially strengthened by the arrival of the First Vermont Militia, under Colonel J. W. Phelps, and several New York regiments, General Butler, then being in command, ordered Colonel Phelps to make a reconnoissance in Hampton and vicinity. Upon approaching the bridge over Hampton Creek, Colonel Phelps discovered that the enemy had fired it. The flames were partially extinguished, but the bridge was so nearly destroyed, that the troops were obliged to cross the river in scows and flat-boats. Upon the arrival of the Vermont troops, the Confederate militia and all the inhabitants, save the negroes and one white family, fled the town, leaving behind them, in many instances, their household furniture and other personal effects.

On the afternoon of the same day, General Butler, with Company B of the Third Regiment and Captain Tyler’s company, proceeded some seven miles into the enemy’s country, in the direction of Yorktown. This was the first reconnoissance which the volunteers had made, and consequently proved very interesting to them.

There was no lack of work for these troops, and every day found them engaged in some highly necessary, though not always pleasant, service.

The summer was at its height, the days were hot and sultry, while the nights were often cold and damp. The men were frequently obliged to engage all day in the most laborious occupations, and at night go on guard.
