This Week in the Civil War - 731
December 25, 1863, the third Christmas Day of the Civil War in America. In a report Union Naval Commander James Strong noted that he arrived at the mouth of the Rio Grande River aboard the USS Monongahela on Christmas Day, 1863 to discover some 60 vessels anchored in nearby Mexican waters.
He noted that most of the ships were there to land goods in Mexico for the Confederacy. The goods would be transported by land across the Rio Grande above the area occupied by Union troops and turned over to Texan, Confederate authorities.
Commander Strong averred that the crews of these ships spent Christmas eve loudly singing Confederate songs, firing guns, and cheering for the South. So Christmas was observed in a celebratory fashion even south of the Rio Grande!!!
