Right, Murray--

The British call equivalent to -Taps- is known as -Last Post-- and is played following -Tattoo,- which is a call to quarters. The OED gives the use of -taps- as a term used in the American army. I suspect that most armies have a -last call,- or -lights out- or whatever; in the American military that last call became known as -taps-. What, I wonder, is the term used for the last call in the French army (so many American millitary terms were borrowed from the French)?
