Sousa Lobo he met in person, and Lacerda, through the telephone. He repeated his position as a legalist, to which Sousa Lobo agreed, and gave them orders. The regiments conducted recon and, I’m mostly sure, remained in their quarters. There is a vague mention that there was a force moving towards São Paulo which later had to reverse course, it might have been the 6th. On 11:00-11:30 he was phoned by the military cabinet chief, Assis Brasil, and Goulart himself. He stated his situation: in control, but on a disadvantage if the rest of the IInd Army defected and marched against him. He was promised reinforcements: the School-Unit Group and a tank battalion, which he considered good enough to mount a stand.

Such was the situation at night:
4th Infantry Division in rebellion against the government, moved towards Rio de Janeiro. To be exact, it only moved the Tiradentes detachment while fractions went north to Brasília.

School-Unit Group directed to the Paraíba valley to reinforce Zerbini
IInd Army formations in the Paraíba valley under Zerbini. Conduct reconnaissance.
IInd Army undecided, parts already moved towards the Paraíba valley.

Minas Gerais had around 4.000 men on the Army and 18.000 police, and its Tiradentes detachment had 2.714 men. The force moved to Brasília was ~2.000 men.
Rio de Janeiro had 30.000 men on the Army plus more in the marines. I’ve got no numbers on São Paulo.

As you can see 3 of Zerbini’s orders are northwards, to the rebellion in Minas Gerais, over the Mantiqueira range which is a strong defensive position with a handful of chokepoints, including the tunnel. The 6th Infantry’s recon made contact with the engineering battalion in Itajubá and found nothing out of the ordinary. There were two other potential threats, from a police battalion in the general region (but Zerbini wouldn’t know) and from an artillery group in Pouso Alegre. This group was, beyond Zerbini’s knowledge, moving to Belo Horizonte as part of the group that would advance on Brasília, and, without any knowledge of Zerbini, feared what could happen in São Paulo to their rear.
The other order was towards the rest of the IInd Army, on the Dutra’s bridge in Jacareí.
