What was the intended ending of Monty Python and the Holy Grail?

So, if you believe Eric’s account, the movie ended the way it was written, and it was written that way because they couldn’t afford to hire enough extras at £4 a day to film a convincing battle scene. No matter how many camera angles they used to film the few students they did have, it wasn’t enough. Using the police to end the picture was a cheaper and much easier solution.
