The following extract is from it letter written by an officer on board the United States steamer Richmond, after the bombardment of Fort Pickens :

I went by invitation of Lieut.—— ,of the Engineers, to visit the fort. We took a circuit first of the covered way, then of the parapet and ramparts. All around the Fort, inside and out, were marks of the enemy’s shot and shell. On the glacis, here and there, were deep groves, ending in a large hole, where the shot had plumped into it, and where there bad been shell which had burst. The hole was a great excavation into which you could have driven an ox cart. Where the projectiles have struck the standing walls they have chipped off patches of the brickwork, (it is a brick and not a stone fort) perhaps eight or ten inches deep, and where they have struck the corners large portions have been removed but in no case has any part of the fortification received an injury tending in the least to weaken it, and this after two days’ heavy firing.

Fight Between Col. Wilson’s Zouaves and Mississippi, Louisiana, and Alabama Soldiers on Santa Rosa Island

Baltimore, Oct. 12,1811.

The Norfolk Day Book, received this morning, contains despatches from New Orleans giving an account of a surprise and attack made on Col. Wm. Wilson’s Zouaves, at Rosa Island, on the 8th inst. Detachments from several Mississippi, Louisiana and Alabama regiments made a landing in the night and drove in Wilson’s pickets, and shortly afterwards a fierce fight began. The Zouaves of Colonel Wilson are credited with having fought with great bravery, and the rebels admit a loss of forty killed and about double that number wounded. The rebels claim to have spiked the guns of the Zouaves and destroyed all their camp equipage. They also claim to have committed great slaughter among the Zouaves, but give no number of the killed. The rebels also say they carried off a number of prisoners.
