Hit the sack in real sentences

Where does Hit the sack come from?

English Wiktionary’s earliest quote is a 1953 New York Times caption about tired soldiers, and the phrase sounds like American military slang of that time. “Sack” was already slang for a bed or bunk, probably from the old straw-filled sacks people slept on. Wiktionary’s note that farmers slept on sacks of hay is a guess, not a documented origin, and the older “hit the hay” may have been the model.
