led an assault force of 400 (200 marines and 200 militia) ashore before dawn at Dyce's Head on the western tip of the peninsula with orders to capture Fort George. They landed on the narrow beach and advanced up the steep bluff leading to the fort. The British pickets, who included Lieutenant John Moore, put up a determined resistance but received no reinforcement from the fort and were forced to retire, leaving the Americans in possession of the heights. Eight British troops were captured. At this point, Lovell ordered the attackers to halt and entrench where they were. Instead of assaulting the fort, Lovell had decided to build a battery within "a hundred rods" of the British lines and bombard them into surrender. The American casualties in the assault had been severe: "one hundred out of four hundred men on the shore and bank", with the Continental Marines suffering more heavily than the militia. Commodore Saltonstall was so appalled by the losses incurred by his marines that he refused to land any more and even threatened to recall those already on shore. In addition his flagship, the Continental frigate Warren, suffered considerable damage during the engagement with hits to the warship's mainmast, forestay and gammoning. Although possessing significant naval superiority over the British, over the next two weeks the excessively cautious Saltonstall dawdled despite repeated requests by General Lovell that he attack Mowatt's position at the entrance to the harbor. Instead he largely maneuvered the American fleet around the mouth of the Penobscot River beyond the range of the British guns with only occasional ineffective attempts to engage the British. As long as the British warships continued to hold the harbor they were able to pin down the American forces on the ground with concentrated fire and prevent them from taking Fort George. Realizing that time was running out, on August 11 General Lovell again wrote to Saltonstall pleading for him to attack saying: "I mean not to determine on your mode of attack; but it appears to me so very practicable, that any farther delay must be infamous; and I have it this moment by a deserter from one of their ships, that the moment you enter the harbour they will destroy them." Saltonstall's ineptitude at Penobscot would lead to his being dismissed from the Navy as being "ever after incompetent to hold a government office or state post"
