All but that one bay of Battery Ruggles was pretty effectively fenced off from me, the public. This administrative-looking building is out in front of the battery, right next to a tennis court that probably doesn't date to the early 1900's.

Okay ACTUALLY Battery Ruggles was originally called Battery Anderson, built in 1898 and named for Brigadier General Robert Anderson, who commanded Fort Sumpter in South Carolina at the start of the US Civil War, and who died in 1871. In 1906 the battery's two northernmost batteries were renamed Battery Ruggles, after Brigadier General George D. Ruggles, who fought for the Union in the Civil War.

When researching the name Ruggles, I came across, once again, the man I was quite certain the battery had been named after: Brigadier General Daniel Ruggles, who led a division of artillery for the CSA at the Battle of Shiloh: He's credited with tipping the balance of the battle in the Confederacy's favor by concentrating 62 cannon into the "Hornet's Nest." He sure seemed like somebody worth naming a battery after, but...he was a Confederate. And as much as the US Army may have come to accept Jefferson Davis as not necessarily the fire-breathing warlock as which they initially thought of him, it would probably be another generation or so before US Army attitudes softened towards Confederates in general. Or even Brigadier General.
