March 11th. After failing to get up the river at this Pass we to-day steamed round to South-West Pass to try the depth of water there. We found the U. S. steam frigate Colorado here, besides several transports. On the following day the Brooklyn went over this bar and anchored on the other side. The Hartford followed on the 13th and all proceeded to Pilot Town, a little settlement just above the mouth of the Pass. Here it was decided to strip the ship for action; this occupied the 14th. We sent a guard of marines ashore to protect our property, and the flag which was raised on the lookout by Lieut. Kautz, Lieut. Broome of the marines, and Mr. Osbon; the guns were all shotted, and preparations made for any demonstration of the enemy.
