In Texas, the bodies of the German-American victims of the 1862 "Nueces Massacre" are buried together.

On August 10, 1862, sixty Union sympathizing German-American Texans seeking to flee to Mexico were intercepted by Confederate troops and defeated at the Battle of Nueces. Thirty-seven were killed in action or later executed.  In Comfort, Texas, their recovered bodies were buried in a mass grave, with several hundred people in attendance.  A memorial on the site was planned and dedicated later, on August 10, 1866.
