Tonight the transports Tigress, Anglo-Saxon, Cheeseman, Empire City, Horizon and Moderator, all loaded with army supplies, ran the batteries.  Five of them were hit by the Vicksburg guns, though the Tigress was the only one sereiously damaged.  She received a shot in her hull below the water line.  She sank near the Louisiana shore soon after passing beyond the range of the guns.
