Putnam rode about Bunker’s Hill and its skirts, to rally and bring on reinforcements which had been checked or scattered in crossing Charlestown Neck by the raking fire from the ships and batteries. Before many could be brought to the scene of action the British had commenced their second attack. They again ascended the hill to storm the redoubt; their advance was covered as before by discharges of artillery. Charlestown, which had annoyed them on their first attack by a flanking fire, was in flames, by shells thrown from Copp’s Hill, and by marines from the ships. Being built of wood, the place was soon wrapped in a general conflagration. The thunder of artillery from batteries and ships; the bursting of bomb-shells; the sharp discharges of musketry; the shouts and yells of the combatants; the crash of burning buildings, and the dense volumes of smoke, which obscured the summer sun, all formed a tremendous spectacle. “Sure I am,” said Burgoyne in one of his letters--“Sure I am nothing ever has or ever can be more dreadfully terrible than what was to be seen or heard at this time. The most incessant discharge of guns that ever was heard by mortal ears.” The American troops, although unused to war, stood undismayed amidst a scene where it was bursting upon them with all its horrors. Reserving their fire, as before, until the enemy was close at hand, they again poured forth repeated volleys with the fatal aim of sharpshooters. The British stood the first shock, and continued to advance; but the incessant stream of fire staggered them. Their officers remonstrated, threatened, and even attempted to goad them on with their swords, but the havoc was too deadly; whole ranks were mowed down; many of the officers were either slain or wounded, and among them several of the staff of General Howe. The troops again gave way and retreated down the hill. All this passed under the eye of thousands of spectators of both sexes and all ages, watching from afar every turn of a battle in which the lives of those most dear to them were at hazard. The British soldiery in Boston gazed with astonishment and almost incredulity at the resolute and protracted stand of raw militia whom they had been taught to despise, and at the havoc made among their own veteran troops. Every convoy of wounded brought over to the town increased their consternation; and General Clinton, who had watched the action from Copp’s Hill, embarking in a boat, hurried over as a volunteer, taking with him reinforcements.
