Although she missed the kind-hearted Irving family who had been so good to her, it was a pleasure to be with her parents again, and Molly put on her rough farm garments once more, and early and late was out among the cattle, or working in the fields. And she had a joyful surprise when her husband paid her a flying visit a few days later. After that, he came quite frequently, though always unexpectedly, and if proof was wanting that she was the kind of a wife that John Hays was proud to have his fellow-soldiers see, it lies in the fact that he allowed Molly to visit him in camp more than once. She saw him at Trenton, and at Princeton, before the Continental army routed the British there, on January 3, 1777.
In order to surprise the three British regiments which were at Princeton at that time, General Washington, Commander-in-chief of the Continental force, quietly left Trenton with his troops, and crept up behind the unsuspecting British at Princeton, killing about one hundred men and taking three hundred prisoners, while his own losses were only thirty men. Then, anxious to get away before Lord Cornwallis could arrive with reinforcements for the British, he slipped away with his men to Morristown, New Jersey, while the cannon were still booming on the battle-field, their noise being mistaken in Trenton for thunder. With the Continental troops went John Hays, gunner, and as soon as Molly heard of the engagement, and the retirement of General Washington's troops, she hastened to the field of action to seek out any wounded men whom she could care for or comfort in their last hours. Picking her way across the littered field, she brought a drink of water here, lifted an aching head there, and covered the faces of those who had seen their last battle. As she passed slowly on, she saw a friend of her husband's, Dilwyn by name, lying half buried under a pile of debris. She would have passed him by but for a feeble movement of his hand under the rubbish, seeing which, she stooped down, pushed aside his covering, and felt for his pulse to see whether he were still alive. As she bent down her quick eye saw a cannon near where the wounded man lay, a heavy, cumbersome gun which the Continentals had evidently left behind as being of a type too heavy to drag with them on their hasty march to Morristown. Beside the cannon Molly also saw a lighted fuse slowly burning down at one end. She had a temptation as she looked at the piece of rope soaked in some combustible, lying there ready to achieve its purpose. She stooped over Dilwyn again, then she rose and went to the cannon, fuse in hand. In a half-second the booming of the great gun shook the battle-field—Molly had touched it off, and at exactly the right moment, for even then the advance guard of Lord Cornwallis and his men was within range!
At the sound of the cannon they halted abruptly, in alarm. The foe must be lurking in ambush dangerously near them, for who else would have set off the gun? They spent an hour hunting for the concealed Continentals, while Molly picked Dilwyn up and laid him across her shoulder as she had carried the wheat-bags in childhood, and coolly walked past the British, who by that time were swarming across the battle-field, paying no attention to the red-headed young woman carrying a wounded soldier off the field, for what could she have to do with discharging a gun!
Molly meanwhile bore her heavy burden across the fields for two miles until she reached the farm, where she laid the wounded man gently down on a bed which was blissfully soft to his aching bones, and where he was cared for and nursed as if he had been Molly's own kin. When at last he was well again and able to ride away from the farm, he expressed his admiration for his nurse in no measured terms, and there came to her a few days later a box of fine dress goods with the warmest regards of "one whose life you saved." As she looked at the rich material, Molly smoothed it appreciatively with roughened hand, then she laid the bundle away among her most cherished possessions, but making use of it never entered her mind—it was much too handsome for that!
Every hour the British troops were delayed at Princeton was of great advantage to the Continental forces, and by midnight they had come to the end of their eighteen-mile march, to their great rejoicing, as it had been a terrible walk over snow and ice and in such bitter cold that many a finger and ear were frozen, and all had suffered severely. The men had not had a meal for twenty-four hours, had made the long march on top of heavy fighting, and when they reached their destination they were so exhausted that the moment they halted they dropped and fell into a heavy sleep.
While they were marching toward Morristown, Lord Cornwallis was rushing his troops on to New Brunswick to save the supplies which the British had stored there. To his great relief he found them untouched, so he gave up the pursuit of Washington's fleeing forces, and the Continental army, without resistance, went into winter quarters at Morristown, as their Commander had planned to do. While John Hays, with the American army, was following his Commander, Molly, at the farm, had become the proud mother of a son, who was named John Hays, Jr., and who became Molly's greatest comfort in the long months when she had no glimpse or tidings of her husband. Then came news—General Washington's troops were again on the march, passing through New Jersey toward New York. There would be a chance to see her husband, and Molly determined to take it, whatever risk or hardship it might entail, for not only did she long to see Hays, but she could not wait longer to tell him of the perfections of their son. And so Molly went to the scene of the battle of Monmouth.
It was Sunday, the 28th of June, 1778, a day which has come down in history, not only because of the battle which marks its date, but because of its scorching heat. The mercury stood near the 100 mark, and man and beast were well-nigh overcome.
History tells us that the British had remained at Philadelphia until early in June, when they had evacuated that city and crossed the Delaware River on June the eighteenth, with an intention to march across New Jersey to New York. Having heard of this movement of the British, General Washington, with a force nearly equal to that of the enemy, also crossed into New Jersey, with the purpose of retarding the British march and, if opportunity offered, bring on a general engagement. By the 22d of June the whole of the American force was massed on the east bank of the Delaware in a condition and position to give the enemy battle. Despite some opposition on the part of General Lee and other officers, Lafayette and Greene agreed with General Washington in his opinion that the time to strike had come, and soon orders were given which led to the battle of Monmouth.
Lafayette was detached with a strong body of troops to follow up the British rear and act, if occasion presented. Other riflemen and militia were in advance of him and on his flanks, making a strong body of picked troops. To protect his twelve-mile baggage-train from these troops, Sir Henry Clinton placed them with a large escort under Knyphausen, while he united the rest of his force in the rear to check the enemy, if they came too close. The distance between Knyphausen's force and that which brought up the rear suggested the idea to Washington to concentrate his assault on the rear force, and to hasten the attack before the British should reach the high ground of Middletown, about twelve miles away, where they would be comparatively safe.
At once General Lee was sent forward to join Lafayette, with instructions to engage the enemy in such action as was possible until the remainder of the troops should arrive. Lee carried out his part of the command in such a half-hearted way as to bring severe censure on him later, and when General Greene arrived on the scene of action, Lee and his men were in retreat.
