Spanish republicans in the french army

Hello indy and time ghost team, real congratulations for your effort from spain. A fairly well known fact heare is the “Nueve” division, the 9th division of the 2nd mechanized force in thr free french army, said to be the first in entering Paris, composed of spanish republican exiles, can you talk a bit about its history? Maybe comparing them to the othe spanish fascist volunteer force, the blue division
Once again, thank you so much for your effort!
