August 30, 1862, The Charleston Mercury
On Thursday night quite a stir was observed among the enemy’s vessels blockading our harbor. A single gun was fired, and frequent flashes of gunpowder lit up the darkness. A bright blue light was displayed at the head of the Maffit Channel, another in the Ship Channel, and still another some distance out at sea. On Friday morning, instead of the fourteen blockading vessels which had strung their dark hulks along the horizon on the evening before, only seven were in sight. During the day, however, some of the missing vessels came straggling in and resumed their old position.
