At the end of 1777, while still but twenty-five years old, Morris was elected to the Continental Congress, and took his seat in that body at Yorktown in the following January.

He was immediately appointed as one of a committee of five members to go to Washington's headquarters at Valley Forge and examine into the condition of the continental troops.

The dreadful suffering of the American army in this winter camp was such that its memory has literally eaten its way into the hearts of our people, and it comes before our minds with a vividness that dims the remembrance of any other disaster. Washington's gaunt, half-starved continentals, shoeless and ragged, shivered in their crazy huts, worn out by want and illness, and by the bitter cold; while the members of the Continental Congress not only failed to support them in the present, but even grudged them the poor gift of a promise of half-pay in the future. Some of the delegates, headed by Samuel Adams, were actually caballing against the great chief himself, the one hope of America. Meanwhile the States looked askance at each other, and each sunk into supine indifference when its own borders were for the moment left unthreatened by the foe. Throughout the Revolutionary War our people hardly once pulled with a will together; although almost every locality in turn, on some one occasion, varied its lethargy by a spasm of terrible energy. Yet, again, it must be remembered that we were never more to be dreaded than when our last hope seemed gone; and if the people were unwilling to show the wisdom and self-sacrifice that would have insured success, they were equally determined under no circumstances whatever to acknowledge final defeat.

To Jay, with whom he was always intimate, Morris wrote in strong terms from Valley Forge, painting things as they were, but without a shadow of doubt or distrust; for he by this time saw clearly enough that in American warfare the darkest hour was often followed close indeed by dawn. "The skeleton of an army presents itself to our eyes in a naked, starving condition, out of health, out of spirits. But I have seen Fort George in 1777." The last sentence refers to what he saw of Schuyler's forces, when affairs in New York State were at the blackest, just before the tide began to turn against Burgoyne. He then went on to beseech Jay to exert himself to the utmost on the great question of taxation, the most vital of all. Morris himself was so good a financier that revolutionary financial economics drove him almost wild. The Continental Congress, of which he had just become a member, he did not esteem very highly, and dismissed it, as well as the currency, as having "both depreciated." The State of Pennsylvania, he remarked, was "sick unto death;" and added that "Sir William [the British general] would prove a most damnable physician."

Most wisely, in examining and reporting, he paid heed almost exclusively to Washington's recommendations, and the plan he and his colleagues produced was little more than an enlargement of the general's suggestions as to filling out the regiments, regulating rank, modeling the various departments, etc. In fact, Morris now devoted himself to securing the approval of Congress for Washington's various plans.

In urging one of the most important of these he encountered very determined opposition. Washington was particularly desirous of securing a permanent provision for the officers by the establishment of a system of half-pay, stating that without some such arrangement he saw no hope whatever for the salvation of the cause; for as things then were the officers were leaving day by day; and of those who went home on furlough to the Eastern and Southern States, many, instead of returning, went into some lucrative employment. This fact, by the way, while showing the difficulties with which Washington had to deal, and therefore his greatness, since he successfully dealt with them, at the same time puts the officers of the Revolution in no very favorable light as compared with their descendants at the time of the great rebellion; and the Continental Congress makes a still worse showing.

When Morris tried to push through a measure providing for half-pay for life he was fought, tooth and nail, by many of his colleagues, including, to their lasting discredit be it said, every delegate from New England. The folly of these ultra-democratic delegates almost passes belief. They seemed incapable of learning how the fight for liberty should be made. Their leaders, like Samuel Adams and John Hancock, did admirable service in exciting the Americans to make the struggle; but once it was begun, their function ended, and from thence onward they hampered almost as much as they helped the patriot cause. New England, too, had passed through the period when its patriotic fervor was at white heat. It still remained as resolute as ever; and if the danger had been once more brought home to its very door-sill, then it would have risen again as it had risen before; but without the spur of an immediate necessity it moved but sluggishly.

The New Englanders were joined by the South Carolina delegates. Morris was backed by the members from New York, Virginia, and the other States, and he won the victory, but not without being obliged to accept amendments that took away some of the good of the measure. Half-pay was granted, but it was only to last for seven years after the close of the war; and the paltry bounty of eighty dollars was to be given to every soldier who served out his time to the end.

At the same period Morris was engaged on numerous other committees, dealing chiefly with the finances, or with the remedy of abuses that had crept into the administration of the army. In one of his reports he exposed thoroughly the frightful waste in the purchase and distribution of supplies, and, what was much worse, the accompanying frauds. These frauds had become a most serious evil; Jay, in one of his letters to Morris, had already urgently requested him to turn his attention especially to stopping the officers, in particular those of the staff, from themselves engaging in trade, on account of the jobbing and swindling that it produced. The shoddy contractors of the Civil War had plenty of predecessors in the Revolution.

When these events occurred, in the spring of 1778, it was already three years after the fight at Lexington; certainly, the continental armies of that time do not compare favorably, even taking all difficulties into account, with the Confederate forces which, in 1864, three years after the fall of Sumter, fronted Grant and Sherman. The men of the Revolution failed to show the capacity to organize for fighting purposes, and the ability to bend all energies towards the attainment of a given end, which their great-grandsons of the Civil War, both at the North and the South, possessed. Yet, after all, their very follies sprang from their virtues, from their inborn love of freedom, and their impatience of the control of outsiders. So fierce had they been in their opposition to the rule of foreigners that they were now hardly willing to submit to being ruled by themselves; they had seen power so abused that they feared its very use; they were anxious to assert their independence of all mankind, even of each other. Stubborn, honest, and fearless, they were taught with difficulty, and only by the grinding logic of an imperious necessity, that it was no surrender of their freedom to submit to rulers chosen by themselves, through whom alone that freedom could be won. They had not yet learned that right could be enforced only by might, that union was to the full as important as liberty, because it was the prerequisite condition for the establishment and preservation of liberty.
