An ancient Serbian general was once involved in a plot to overthrow
the king. His plot included a number of followers in the upper ranks of
the army. However, his plot was uncovered, and the king threw him in
jail. The king sentenced him to death without a trial.
However, from the jail he was able to secretly contact his
followers to arrange to escape, meet his followers, and attack the
king's palace at night. So the night before his scheduled execution, the
general managed to escape from prison. He fled to a ziggurat several
kilometers away, where his followers would meet him. However, the
ziggurat was one of several in the area, and he wasn't sure if his
cohorts would find the right ziggurat. By this time it was twilight, so
he lit a small fire and sent smoke signals to indicate in which
structure he was hiding.
However, the king's loyal soldiers saw the smoke coming from the
ziggurat, and came to arrest him before he could meet his followers. He
was executed later that day.
The moral of the story? WARNING: The Serbian general has
determined that smoking ziggurats can be extremely hazardous to your
stealth.
