[Footnote 73: It is not unworthy of notice, that the ladies of Baltimore charged themselves with the toil of immediately making up the summer clothing for the troops. Innumerable instances of their zeal in the common cause of their country were given in every state in the union.] Having made these preparations for the campaign, he marched with the utmost celerity to the defence of Virginia. That state was in great need of assistance. The enemy had penetrated deep into its bosom, and was committing those excesses on its inhabitants to which a country unable to repel invasion must always be exposed. General Philips, on his arrival, took command of all the British troops in Virginia; and, after completing the fortification of Portsmouth, commenced offensive operations. [Sidenote: April 24.] About two thousand five hundred men were embarked on board some small vessels, and landed at various places in the neighbourhood of Williamsburg. Different detachments spread themselves over the lower part of that neck of land which is made by York and James Rivers; and, after destroying, without opposition, a ship yard belonging to the state, with some armed vessels and public stores, re-embarked and proceeded to City Point, where they landed in the afternoon of the 24th. The next day they marched against Petersburg, at which place, immense quantities of tobacco and other stores were deposited. Baron Steuben was not in a situation to check their progress. The levies of Virginia had marched to the aid of General Greene; and the whole number of militia, at that time in the field, did not much exceed two thousand men. Unwilling to abandon so important a place as Petersburg without the semblance of fighting, the baron posted about one thousand men a mile below the town with orders to skirmish with the enemy. The British troops, without being able to bring him to a close engagement, were two or three hours employed in driving him across the Appomattox, the bridge over which being taken up as soon as the militia had passed it, farther pursuit became impracticable. This skirmish having terminated with scarcely any loss on either side, the baron retreated towards Richmond, and Philips took quiet possession of Petersburg; where he destroyed a considerable quantity of tobacco, and all the vessels lying in the river. This service being accomplished, Arnold was detached through Osbornes to Warwick, between which place and Richmond, a respectable naval force, consisting of small armed vessels, had been collected with the intention of co-operating with the French fleet against Portsmouth; and a few militia were stationed on the northern bank of the river to assist in defending the flotilla.
