It is a bit like the History question: "Who was what in what of whom?"

A traditional British equivalent is "Who dragged whom how many times
around the walls of where?", which does have just about enough context.

Yes. "Joshua, Isrelites, seven, Jericho" is wrong by a hair....

Hmmm.  Achilles, Hector, ?, Troy.

http://en.wikipedia.org/wiki/Achilles:

Achilles chased Hector around the wall of Troy three times before
Athena, in the form of Hector's favorite and dearest brother, Deiphobus,
persuaded Hector to stop running and fight Achilles face to face. After
Hector realized the trick, he knew his death was inevitable and accepted
his fate. Hector, wanting to go down fighting, charged at Achilles with
his only weapon, his sword. Achilles got his vengeance, killing Hector
with a single blow to the neck. He then tied Hector's body to his
chariot and dragged it around the battlefield for nine days.
