#68a, 10c Dark Green tied on Eagle and Flags Patriotic Cover via U.S.S. Lancaster Panama Bay, to Missouri

Manuscript ship marking “U.S.S. Lancaster, Panama Bay N.G.” at lower left with "DUE 10" straightline. Addressed to St. Joseph, Missouri. The cover with pressed edged and small sealed tear, otherwise Very Fine.

On 11 November 1864, a secret expedition of boats from the USS Lancaster captured a party of Confederate officers aboard the passenger steamer Salvador, off the Bay of Panama. They had planned to seize the Salvador for the Confederate Government and convert her into a raider to capture Union gold shipments from California. It is possible that this cover was aboard the U.S.S. Lancaster during this historic capture.
