MARCH 21ST, 1862: Major General Halleck wrote Flag Officer Foote, commenting on the Navy's operation against the Confederate batteries on Island No. 10: "While I am certain that you have done everything that could be done successfully to reduce these works, I am very glad that you have not unnecessarily exposed your gunboats.
"If you had been disabled, it would have been a most serious loss to us in the future operations of the campaign.... Nothing is lost by a little delay there."
Foote's gunboat and mortar flotilla continued to bombard the works with telling effect.
