MAY 3RD, 1864: The USS Chocura captured blockade-running British schooner Agnes off the mouth of the Brazos River, Texas, with cotton cargo. Later that day, the Chocura also captured the Prussian schooner Frederick the Second, also with cotton, which had run out with the Agnes.
I did not know that the Prussians were involved in blockade-running.
The USS Virginia captured the schooner Experiment off the Texas coast with a cargo of cotton. After removing the cotton, the Virginia destroyed it.
