From Porto Alegre Silvino repeteadly contacted his subordinate units and issued northward orders but they were ignored. The only legalist, the 13th Infantry Regiment's commander, had been promptly dismissed by Dário and the others. The 5th Region also had the governor, police, Navy and Air Force on its side. It was worried about fuel and began rationing and forming stocks through the railways. Securing the ports and the other state capital (Florianópolis) were also necessary.
The Region's actions, starting with ensuring the IInd Army would be on their side, show a reliance on their stronger northern neighbor, which continued with São Paulo dispatching Tactical Group 4, which arrived in Curitiba at 23:00 on the 2nd, and a tanker which delivered fuel to Paranaguá at the 4th.
In the meantime it sent three detachments, Beta, Lages and Litoral towards the border with Rio Grande to fend off the rest of the IIIrd Army. If needed they could retreat as far as the Joaçaba-Lages-Criciúma line.
The Region's forces were:

Beta Detachment
5th Combat Engineer Battalion
2nd Independent Cavalry Squadron
1st Company of the 13th Infantry Regiment (didn't move by the commander's decision)

Lages Detachment
2nd Highway Battalion
Battalion of the 13th Infantry Regiment
1st/5th Howitzer Regiment
5th Mech Recon Squadron

Litoral Detachment
