"That the said Committee be directed to send all the Oak Plank which they may have in their Possession, to Mount Washington with the utmost Dispatch."
Governor's Island.—The obstructions in the East River between Governor's Island and the Battery consisted of hulks sunk in the Channel. This was not done until a few days before the battle on Long Island. Colonel Douglas, as he states, sounded the river. The present Buttermilk Channel, between the island and Brooklyn, was not obstructed. Governor's Island was evacuated on the morning of the retreat from Long Island, but the enemy failed to take possession for two days. The interval was improved by the Americans in carrying off all except the heavy pieces to New York in the night-time.
Battle of Long Island.—The prisoners named in [Document 58] as having been captured by us at the battle of Long Island were a small party of marines, who mistook the Delaware regiment in Stirling's force for Hessians. They came too near and were taken by Lieut. Wm. Popham, who was ordered to march them into camp. He made them cross Gowanus Creek on Stirling's retreat, and brought all but one in safe. Popham afterwards became major and aid to General James Clinton, and settled in New York, where he lived to be over ninety years old. Was a member of the New York Cincinnati. During the battle the marines landed from the fleet, which could not make its way up above Gowanus Bay, and, according to one letter, Admiral Howe furnished Grant with ammunition while fighting Stirling. The Roebuck alone, as already stated, could work its way along far enough to send some harmless long-range shot at the Red Hook fort.
