To be fair, it was the largest cavalry charge in history. Between 30 and 40000 horsemen charging is insane. To put that into a comprehendible context, the charge of the rohirim you see in the Return of the King had 5000 horses. The largest charge in the Napoleonic wars (iirc) was Murats desperation charge at the battle of Eylau with 11000 cavalry, which somewhat won the day and is considered one of the great cavalry charges in history.
This charge was 3 to 4 times larger. It was truly a hurricane of vengeance.

30-40000 sounds like a safe bet
