Lieutenant C. T. BARRETT,

Acting Aide-de-Camp:

I know nothing of the strength of the rebel force at Bayou Sara. I suppose it is only a party of Scott's force with some artillery. They fired upon the steamers White Cloud and Choteau yesterday morning. No one hurt and no great damage done. The firing was with cannon and small-arms. The gun-boats 14 and 54 are said to have hastened to the scene of action. The firing on the White Cloud took place near an island below Bayou Sara. The Choteau is reported fired upon above Bayou Sara from this side of the river in both cases. My opinion is the gun-boats only can measurably protect steamers. Unless the country back from the river is held by our forces there can be on effectual protection given by the army, and that for the present appears to be out of the question.

Brigadier-General of Volunteers.
