I came across this excerpt that was put up as a "joke" in an issue of the Reader's Digest:
After invading Greece, Philip II of Macedon sent a threatening message to the Spartans: "You are advised to submit without delay, for if I bring my army on your land, I will destroy your farms, slay your people and raze your city."
The Spartans replied with one word: "If"
Given the modern-day image of the Spartans being superb, tough warriors, and the hilarity of this "joke" aside...
1) Did Philip II actually send this message to the Spartans? When was this?
2) Did the Spartans actually taunt him with the word "if"?
3) If not the above, did something even remotely similar occur?
