How many Celts were fighting in the battle field?

The number of Celts fighting in a specific battle can vary widely depending on the historical context and the particular conflict being referenced. For instance, during the Gallic Wars, estimates suggest that tens of thousands of Celtic warriors participated in battles against Roman forces. However, for specific battles, such as the Battle of Gergovia or Alesia, the numbers can differ significantly, often ranging from a few thousand to over 100,000. Without a specific battle in mind, it's challenging to provide an exact figure.
