...t Mountain, on the 13th of December, in which we were successful. Rumours also of a fight on the Chesapeake and Ohio Canal; and another rumour that England has demanded the restoration of Mason and Slidell , and in case of non-compliance with the demand, that Lord Lyons should demand his passports. How ardently I do wish that England would break up the blockade!
