In Rome, you were more than likely never see a battle with 10,000 men on the field at once. Economic and population factors limit this.
Online though? Certainly possible.
Personally I think the most I've had on screen was around 5 or 6 thousand. Two huge armies squaring off. However, the biggest battle I've ever fought was o Shogun: Total War. My state and the last remaining clan had been building up armies on respective borders. When we finally engaged, there were roughly 25,000 men. Many reinforcements that day.
