In one of the Brewer quotes, Pyrrhus is said to have admitted that he thought the Romans
were just another bunch of barbarians. He knew nothing of their military tactics, and had
no way of knowing until too late that they were superior to the older Greek ones.
The Making of the Roman Army, by Lawrence Keppie, says first mention of "Pyrric Victory"
in Englsish was Daily Telegraph in 1885.
