A submarine pen (U-Boot-Bunker in German) is a bunker which is designed to protect submarines from air attack. The term is generally applied to submarine bases constructed during World War II, particularly in Germany and the occupied countries which were also known as U-boat pens (after the phrase "U-boat" to refer to German submarines).
Famous quotes containing the word pen:
“Prove that ever I lose more blood with love than I will get again with drinking, pick out mine eyes with a ballad-maker’s pen and hang me up at the door of a brothel-house for the sign of blind Cupid.”
—William Shakespeare (1564–1616)
