Goulart landed in Porto Alegre at 03:58, at around the same time Congressman Mazzili was placed on the "vacant" Presidency.
At 08:00 he conferenced with Brizola and his generals: Ladário, Saraiva, Floriano (3rd Military Region) and others. Ladário and Brizola were of the opinion he should continue the struggle. He'd retreat to his estates in São Borja, in 1st Cavalry territory, leaving behind a reorganized government in Porto Alegre with a mobilization conducted by Brizola (civilian) and Ladário (military). Thousands of Brizola's volunteers would be armed from stocks. Goulart's popularity would rouse up his supporters through the country.
Floriano replied that it would be madness - the military situation was very dire. The 5th Region was marching to the border, behind it the IInd Army and the Navy and Air Force. Only the Porto Alegre, São Leopoldo, Vacaria and Santiago garrisons could still be counted upon. The others were already marching against the capital.

Or that's what most accounts mention. The 6th Infantry and 1st Cavalry divisions were of dubious loyalty.
The Litoral Detachment's most advance units got near the border only at 14:45. At 08:40-09:00 the 2nd and 3rd Cavalry Divisions and the 2nd/9th Infantry (Pelotas) plus a battery of howitzers (Cachoeira do Sul) had been ordered in Porto Alegre's direction. The 2nd also to defend its flank against the 1st Cavalry. However there's nothing on the divisional movements and the infantry battalion only moved after 17:00.
The point wasn't to attack the capital. It was to make the capital think it was under attack. Hence the orders to the divisions were in the open, with no cypher. It worked.

The other generals agreed with Floriano, though allegedly Saraiva still believed he could move his division north, then east, encircle the other formations then march against São Paulo.
To the suggestion of military impossibility, Ladário replied that as a soldier he wanted to fight until a miracle. For Goulart this was an admission that Floriano was right. Rejecting any bloodshed on his defense, at 11:30 he flew to São Borja, from where he'd soon move to exile in Uruguay.
