What Putnam had advocated as the highest strategy, the seizing of some height commanding the British position, was forced upon the irresolute commander-in-chief by the British themselves. Shortly after General Gage's four thousand soldiers had been reenforced by six thousand more, under Howe, Clinton, and Burgoyne, the Americans learned that the enemy intended to take and fortify the heights of Charlestown or Dorchester themselves. As it was then the sixteenth of June, and their move was to be made on the eighteenth, there was no time to lose if they were to be forestalled; so orders were issued by the Committee of Safety, sanctioned by a council of war, for taking possession of Bunker Hill in Charlestown. A detail of a thousand men was made from three Massachusetts regiments, to which, in order to placate General Putnam, two hundred Connecticut soldiers were added under his friend, Captain Knowlton. This small body of militia, with a few field pieces as artillery, was to sally forth to rouse the British lion in his lair. The detachment was placed under Colonel William Prescott, of Massachusetts, General Putnam "having the general superintendence of the expedition," and about nine o'clock at night, after having been paraded on Cambridge Common, and listened to prayer by the president of Harvard College, this devoted band set forth on its mysterious mission. Striding ahead of his men, all of whom had perfect confidence in their beloved officer, Colonel Prescott led the way, accompanied by two sergeants carrying lanterns. Not until they had reached the foot of Bunker Hill, where they found entrenching tools awaiting them which had been sent ahead in wagons, did the rank and file know the object of their march in the night; yet they faltered not, nor displayed a disposition to retreat. Their leaders knew, of course; but even they were in doubt, when once arrived at Charlestown, which of its eminences to select. Their orders explicitly indicated Bunker Hill as the one to fortify, but, "though this was the most commanding and most defensible position, it was too far from the enemy to annoy their army and shipping." Situated nearer the British general position was another elevation, Breed's Hill; but this was only sixty-two feet in height, as compared with Bunker Hill's one hundred and ten. This was finally selected, but only after a long consultation, which lasted until near midnight, when the veteran military engineer, Colonel Gridley (who had been awaiting the decision in great anxiety, owing to the loss of valuable time), at once proceeded to lay out the works.
