The phrase originates from the navy where the signal to retire was the day was to pipe the hammocks down. The phrase was first used in 1798 in "Gillespie's Advice to Commanders & Officers". When the officers wanted peace they would ask the crew to pipe down into the deck space and that is where the meaning of requesting to be quiet comes from. The phrase with this meaning was first used in 1850 in "The Gettysburg Star And Banner".
