Sumter day was celebrated this morning at sunrise by the raising of a flag at the battery by the Anderson Zouaves. On April 14, 1861, Major Robert Anderson retired from Fort Sumter, Charlestone harbour, taking his battle flag with him. On April 14, 1865, he returned, raising it again. The Anderson Zouaves were named for him, and some years ago the family of the Major presented the company with a flag. It is raised annually on Sumter day.
