The Flint Solution

First, my apologies for the lateness in ending the 'quest'. Time has a way of getting away as they say.

Now, on to the answer to the Quest of the World's Greatest Flint:

At the end of Return of the King, Aragorn, Gandalf and company proceed on horseback to the Moranon - the Black Gate - in a feint to draw out Sauron's forces in the hope of making it easier for Frodo and Samwise to make it to Mount Doom.

Gandalf, Aragorn, Legolas, Gimli, Merry and Pipen ride out to parlay with the Mouth of Sauron, end negotiations, and as the gate opens ride back to the main body of troops. The camera then shows the "Men of West" charging forward to battle the hosts of Mordor. Only, now they are on foot. All the horses have magically disappeared.

Call me lightning, but I didn't notice this until last month. I told my daughter about the flint, and she later noted that the International Movie Data Base includes it in its list of 'mistakes'.

C'est la vie!
