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
23rd Infantry Regiment (one company detached to the port)
Reinforced company of the 14th Caçadores Battalion

Reserve in Curitiba
1st Independent Cavalry Squadron
Police battalion
Tactical Group 4
4th Infantry Regiment
2nd 155 mm Howitzer Group
2nd AA Group
Comms and health elements
17th Cavalry Regiment also mentioned as moving, but typically not as part of the group
This is basically the IInd Army reserve  >>/39508/

Plus the forces near the coastline, in Florianópolis backed by the 5th Naval District.

Ladário tried his own troop movements in the opposite reaction. The 3rd Highway Battalion, with a bitterly legalist commander, promptly obeyed and occupied the Socorro Pass at the border, arresting 2 lieutenants, 4 sergeants and some soldiers on the other side. The 2nd Highway Battalion had to entrench further north, and as its mission was to hold the Pass this was a legalist tactical victory.
The IIIrd Army's mobilization would consist of 3 tactical groups marching all the way to the São Paulo border at Silvino's disposal. They weren't drawn from the capital garrison but from the 3rd Infantry and 3rd Cavalry. Forces mobilized in the 3rd Infantry were the:

Battalion of the 7th Infantry Regiment
8th Infantry Regiment
Company of the 3rd Light Tank Battalion
3rd Mech Recon Squadron
Battery of the 3rd Howitzer Regiment

The orders came in at 08:30 and 09:30. In the 3rd Cavalry it is known the 3rd Motorized Cavalry Regiment was called to move but not which other units.

In any case such movement never took place because the officers had pressured Camarinha, Garrastazú and Poppe to switch sides. Poppe's 3rd Infantry Division controlled the state's central rail hub and long before his decision had already paralysed it with his troops at 00:45. Ironically, the powerful local unions which constantly interrupted traffic now wanted to operate the railways to allow Ladário's troop movements but Poppe, who hated the interruptions, wouldn't allow it. 
Hence the 3rd Infantry and 2nd and 3rd Cavalry had gone rogue. Saraiva remained loyal and flew to Porto Alegre but this left his division without leadership. Though a hostile territory to the coupists it couldn't move as the 3rd Infantry controlled the railways.
