Sick, ill-fed, dirty, and ragged, but with a steady nucleus of regular troops as devoted to their great commander as they were disgusted with the hybrid arrangement between the States and Congress, Washington's army worried along. Two months before the battle of the Brandywine, the American General informed the Committee of Congress that "no army was ever worse supplied than ours ... our Soldiers, the greatest part of last Campaign, and the whole of this, have scarcely tasted any kind of Vegetables; had but little salt and Vinegar." He told of the "many putrid diseases incident to the Army, and the lamentable mortality," which this neglect of soldiers in the field had caused. "Soap," says he, "is another article in great demand," but not to be had. He adds, sarcastically: "A soldier's pay will not enable him to purchase [soap] by which his ... consequent dirtiness adds not a little to the disease of the Army."[298]

Such was the army of which John Marshall was a part when it prepared to meet the well-fed, properly clad, adequately equipped British veterans under Howe who had invaded Pennsylvania. Even with such a force Washington felt it necessary to make an impression on disaffected[299] Philadelphia, and, for that purpose, marched through the city on his way to confront the enemy. For it was generally believed that the American army was as small in numbers[300] as it was wretched in equipment. A parade of eleven thousand men[301] through the Tory-infested metropolis would, Washington hoped, hearten patriot sympathizers and encourage Congress. He took pains that his troops should make the best appearance possible. Arms were scoured and the men wore sprigs of green in their headgear. Among the orders for the march through the seat of government it was directed: "If any Soldr. shall dare to quit his ranks He shall receive 39 Lashes at the first halting place afterwards.... Not a Woman[302] belonging to the Army is to be seen with the troops on their March through the City."[303]

The Americans soon came in contact with the enemy and harassed him as much as possible. Many of Washington's men had no guns. Although fewer militia came to his aid than Congress had called for, testifies Marshall, yet "more appeared than could be armed. Those nearest danger were, as usual, most slow in assembling."[304]

Upon Wayne's suggestion, Washington formed "a corps of light infantry consisting of nine officers, eight sergeants, and a hundred rank and file, from each brigade" and placed them under the command of General Maxwell who had acquired a reputation as a hard fighter.[305] Among these picked officers was Captain-Lieutenant John Marshall. Maxwell's command was thrown forward to Iron Hill. "A choice body of men" was detailed from this select light infantry and, during the night, was posted on the road along which it was believed one column of the British army would advance. The small body of Americans had no artillery and its only purpose was to annoy the enemy and retard his progress. The British under Cornwallis attacked as soon as they discovered Maxwell's troops. The Americans quickly were forced to retreat, having lost forty killed and wounded. Only three of the British were killed and but nineteen were wounded.[306]

This action was the first engagement in which Marshall took part after the battle of Great Bridge. It is important only as fixing the command to which he was assigned. Marshall told Justice Story that he was in the Iron Hill fight;[307] and it is certain, therefore, that he was in Maxwell's light infantry and one of the little band picked from that body of choice troops, for the perilous and discouraging task of checking the oncoming British thousands.

The American army retreated to the Brandywine, where on the 9th of September Washington stationed all his forces except the light infantry on the left of the river. The position was skillfully chosen, but vague and conflicting reports[308] of the movement of the British finally resulted in American disaster.

The light infantry was posted among the hills on the right of the stream along the road leading to Chadd's Ford, in order to skirmish with the British when they approached, and, if possible, prevent them from crossing the river. But the enemy, without much effort, drove the Americans across the Brandywine, neither side suffering much loss.[309]

Washington now made his final dispositions for battle. The command to which Marshall belonged, together with other detachments under the general direction of Anthony Wayne, were placed opposite the British at Chadd's Ford. Small parties of selected men crossed over and attacked the British on the other side of the stream. In one of these skirmishes the Americans "killed a British captain with ten or fifteen privates, drove them out of the wood and were on the point of taking a field piece." But large numbers of the enemy hurried forward and again the Americans were thrown across the river. Marshall was in this party.[310]

Thomas Marshall, now colonel,[311] held the advanced position under Sullivan at the right; and his regiment did the hardest fighting and suffered the heaviest losses on that unhappy day. When Cornwallis, in greatly superior numbers, suddenly poured down upon Sullivan's division, he all but surprised the Continentals and drove most of them flying before him;[312] but Colonel Marshall and his Virginians refused to be stampeded. That regiment "maintained its position without losing an inch of ground until both its flanks were turned, its ammunition nearly expended, and more than half the officers and one third of the soldiers were killed and wounded."[313] Colonel Marshall had two horses shot under him. But, cut to pieces as they were, no panic appeared in this superb Virginia command and they "retired in good order."[314]

While Thomas Marshall and his Third Virginia Line were thus checking Cornwallis's assault on the right, the British charged, in dense masses, across the Brandywine, at Chadd's Ford, upon Wayne's division, to which Captain-Lieutenant John Marshall had been assigned. The Americans made a show of resistance, but, learning of the rout of their right wing, quickly gave way.[315]
