The observing chaplain already cited, gazed with wonder at the rapid effects soon produced by the labors of an army. “It is surprising,” writes he, “how much work has been done. The lines are extended almost from Cambridge to Mystic River; very soon it will be morally impossible for the enemy to get between the works, except in one place, which is supposed to be left purposely unfortified, to entice the enemy out of their fortresses. Who would have thought, twelve months past, that all Cambridge and Charlestown would be covered over with American camps, and cut up into forts and intrenchments, and all the lands, fields, orchards, laid common,—horses and cattle feeding on the choicest mowing land, whole fields of corn eaten down to the ground, and large parks of well-regulated forest trees cut down for fire-wood and other public uses.” Beside the main dispositions above mentioned, about seven hundred men were distributed in the small towns and villages along the coast, to prevent depredations by water; and horses were kept ready saddled at various points of the widely extended lines, to convey to head-quarters intelligence of any special movement of the enemy. The army was distributed by Washington into three grand divisions. One, forming the right wing, was stationed on the heights of Roxbury. It was commanded by Major-general Ward, who had under him Brigadier-generals Spencer and Thomas. Another, forming the left wing under Major-general Lee, having with him Brigadier-generals Sullivan and Greene, was stationed on Winter and Prospect Hills; while the centre, under Major-general Putnam and Brigadier-general Heath, was stationed at Cambridge. With Putnam was encamped his favorite officer Knowlton who had been promoted by Congress to the rank of major for his gallantry at Bunker’s Hill. At Washington’s recommendation, Joseph Trumbull, the eldest son of the governor, received on the 24th of July the appointment of commissary-general of the continental army. He had already officiated with talent in that capacity in the Connecticut militia. “There is a great overturning in the camp as to order and regularity,” writes the military chaplain; “new lords, new laws. The generals Washington and Lee are upon the lines every day. New orders from his excellency are read to the respective regiments every morning after prayers. The strictest government is taking place, and great distinction is made between officers and soldiers. Every one is made to know his place and keep it, or be tied up and receive thirty or forty lashes according to his crime. Thousands are at work every day from four till eleven o’clock in the morning.”
