It's worth noting that the present sucessors of the 10th and 11th (their first battalions, other one or other two either sent away or disbanded) are bound together with the former 1st Caçadores battalion of Petrópolis (now 32nd Light Infantry) in the 4th Light Infantry (Mountain) Brigade of the 1st, not 4th division, and are thus under tight oversight from Rio de Janeiro. I can't find this said anywhere but it seems the security threat of having forces so close to the metropolis but not commanded from within it was realized.
