the New London was engaged in ferreting out the enemy's vessels in that river, and therefore Captain Renshaw determined to start next morning for the Pearl river, which he intended to examine. At five o'clock A. M. on the 14th of May, the division got under way, led as on the day before by the Sachem. At ten o'clock, the Jackson, getting out of range, grounded and signalized for assistance. The Sachem was ordered to her relief; but in the mean time, the Coast Survey party had furnished information such as would bring the other steamers safely to the mouth of Pearl river, by keeping along the southern bank in the Rigolets. When the Sachem came up with the Jackson, her captain informed Mr. Gerdes that as the transport boat Whiteman (a prize) was expected to pass soon, she would be expected to lighten and tow the steamer off. The Sachem therefore moved on, and reached the Westfield and Clifton at ten o'clock, at anchor near the mouth of Pearl river. A row of stockades had been set by the enemy quite across that river, leaving only an opening for vessels to pass up and down. This obstruction consisted of heavy pieces of timber inserted vertically in the mud bed, and joined by cross pieces, to which were chained a number of logs so as to float off at right angles. The length extended about three quarters of a mile, and vessels could pass only through the opening, and under the fire of the guns, when Fort Pike was held by the enemy. The expediency of this device is somewhat questionable, as it plainly designated the otherwise intricate channel, and might have enabled a swift steamer to run the batteries without danger of being detained on the extensive mud flats.
