The siege of Boston continued through the winter, without any striking incident to enliven its monotony. The British remained within their works, leaving the beleaguering army slowly to augment its forces. The country was dissatisfied with the inaction of the latter. Even Congress was anxious for some successful blow that might revive popular enthusiasm. Washington shared this anxiety, and had repeatedly, in councils of war, suggested an attack upon the town, but had found a majority of his general officers opposed to it. He had hoped some favorable opportunity would present, when, the harbor being frozen, the troops might approach the town upon the ice. The winter, however, though severe at first, proved a mild one, and the bay continued open. General Putnam, in the mean time, having completed the new works at Lechmere Point, and being desirous of keeping up the spirit of his men, resolved to treat them to an exploit. Accordingly, from his “impregnable fortress” of Cobble Hill, he detached a party of about two hundred, under his favorite officer, Major Knowlton, to surprise and capture a British guard stationed at Charlestown. It was a daring enterprise, and executed with spirit. As Charlestown Neck was completely protected, Knowlton led his men across the mill-dam, round the base of the hill, and immediately below the fort; set fire to the guard-house and some buildings in its vicinity; made several prisoners, and retired without loss; although thundered upon by the cannon of the fort. The exploit was attended by a dramatic effect on which Putnam had not calculated. The British officers, early in the winter, had fitted up a theatre, which was well attended by the troops and tories. On the evening in question, an afterpiece was to be performed, entitled “The Blockade of Boston,” intended as a burlesque on the patriot army which was beleaguering it. Washington is said to have been represented in it as an awkward lout, equipped with a huge wig, and a long rusty sword, attended by a country booby as orderly sergeant, in rustic garb, with an old firelock seven or eight feet long. The theatre was crowded, especially by the military. The first piece was over, and the curtain was rising for the farce, when a sergeant made his appearance, and announced that “the alarm guns were firing at Charlestown, and the Yankees attacking Bunker’s Hill.” At first this was supposed to be a part of the entertainment, until General Howe gave the word, “Officers, to your alarm posts.” Great confusion ensued; every one scrambled out of the theatre as fast as possible. There was, as usual, some shrieking and fainting of ladies; and the farce of “The Blockade of Boston” had a more serious than comic termination.
