Famous quotes containing the words william and/or giles:
“When Wellington thrashed Bonaparte,
As every child can tell,
The House of Peers, throughout the war,
Did nothing in particular,
And did it very well:”
—Sir William Schwenck Gilbert (1836–1911)
“I still feel just as I told you, that I shall come safely out of this war. I felt so the other day when danger was near. I certainly enjoyed the excitement of fighting our way out of Giles to the Narrows as much as any excitement I ever experienced. I had a good deal of anxiety the first hour or two on account of my command, but not a particle on my own account. After that, and after I saw that we were getting on well, it was really jolly. We all joked and laughed and cheered constantly.”
—Rutherford Birchard Hayes (1822–1893)
