"A detachment of the army was ordered to advance early in the evening of that day, and commence the erection of a strong work on the heights in the rear of Charlestown, at that time called Breed's Hill, but from its proximity to Bunker Hill, the battle has taken its name from the latter eminence, which overlooks it. "The work was commenced and carried on under the direction of such engineers as we were able to procure at that time. It was a square redoubt, the curtains of which were about sixty or seventy feet in extent, with an entrenchment, or breast-work, extending fifty or sixty feet from the northern angle, towards Mystic river. "In the course of the night, the ramparts had been raised to the height of six or seven feet, with a small ditch at their base, but it was yet in a rude and very imperfect state. Being in full view from the northern heights of Boston, it was discovered by the enemy, as soon as daylight appeared; and a determination was immediately formed by General Gage, for dislodging our troops from this new and alarming position. Arrangements were promptly made for effecting this important object. The movements of the British troops, indicating an attack, were soon discovered; in consequence of which orders were immediately issued for the march of a considerable part of our army to reinforce the detachment at the redoubts on Breed's Hill; but such was the imperfect state of discipline, the want of knowledge in military science, and the deficiency of the materials of war, that the movement of the troops was extremely irregular and devoid of every thing like concert--each regiment advancing according to the opinions, feelings, or caprice, of its commander. "Colonel Stark's regiment was quartered in Medford, distant about four miles from the point of anticipated attack. It then consisted of thirteen companies, and was probably the largest regiment in the army. About ten o'clock in the morning, he received orders to march. The regiment being destitute of ammunition, it was formed in front of a house occupied as an arsenal, where each man received a gill-cup full of powder, fifteen balls, and one flint. "The several captains were then ordered to march their companies to their respective quarters, and make up their powder and ball into cartridges, with the greatest possible despatch. As there were scarcely two muskets in a company of equal calibre, it was necessary to reduce the size of the balls for many of them; and as but a small proportion of the men had cartridge-boxes, the remainder made use of powder-horns and ball-pouches.
