Also called "The Nuns of the Battlefield", this memorial recognizes nuns ("sisters") who nursed the wounded during the Civil War.

The inscription on the front reads: "They comforted the dying, nursed the wounded, carried hope to the imprisoned, gave in His name a drink of water to the thirsty."

Raised by the Ladies Auxiliary of the Ancient Order of Hibernians, the memorial was originally designed for Arlington Cemetery, until the War Department objected. It was then proposed for location behind the Pan American Union building ... but the Fine Arts Commission objected to that.

Finally, Connor downscaled the size of the memorial and got permission to build it at its present site. Then he had to sue the Ancient Order for payment.
