On the 6th of July, 1775, the Continental Congress sent out its formal Statement, which was read at headquarters in Cambridge on the 15th, and to Putnam's division, then at Prospect Hill, on the 18th. At the same time the new standard recently sent from Connecticut was unfurled, to the acclaim of a mighty "_Amen!_" and the thunder of cannon from the fort. The commotion aroused the British in their dearly-bought stronghold over at Charlestown. In the language of the Essex Gazette, proclaiming this event: "The Philistines on Bunker Hill heard the shouts of the _Israelites_, and being very fearful, paraded themselves in battle array." Putnam's bold stand at Prospect Hill, so promptly taken and so stoutly maintained, kept the enemy within the territory they had purchased with the blood of their best soldiers, and they never advanced any farther into the country they coveted. The lines of investment around Boston were drawn closer and made more nearly impregnable, yet weeks and months went by without any material change in the relative positions of British and Provincials, save that Putnam still kept on digging, and creeping nearer and nearer to the foe. By fortifying Cobble Hill, an elevation that more completely commanded the Charles than his main fortress at Prospect Hill, Putnam was enabled to open fire upon the British men-of-war and floating batteries, and soon silenced and drove them away. Not satisfied with this achievement, a few days later his men were at work upon an entrenchment within half a mile and under the fire of a British man-of-war, a squad of these intrepid soldiers being commanded by his eldest son, Israel. The British were now alarmed, and doubtless believed, in the language of a writer commenting on these events, that "every fort which was defended by General Putnam might be considered as impregnable, if daring courage and intrepidity could always resist superior force." Still, while the British feared to advance upon the Americans, the latter, though eager to drive them out of their stronghold, were unable to do so from lack of artillery and ammunition. This lack was to some extent supplied by the capture of some ordnance ships by our gallant privateers, though as late as January, 1776, one of the Provincial colonels wrote to another: "The bay is open; everything thaws here except Old Put. He is still as hard as ever, crying out for _powder--powder_--ye gods, give us powder!" Cannon-balls, several hundred of them, he had secured (if we may credit a story told at the time) by conspicuously posting some of his men on an elevation in front of a sandy hill in sight of a British war-ship, from which by this ingenious ruse he drew a rain of shot, which supplied his needs for the time being, as they were afterward easily dug out of the sand!
