Camarinha and Garrastazú defected by morning, Poppe by 11:30. Ladário was particularly disappointed by Garrastazú's betrayal as he had pushed his career forward.
In the capital he still had momentum. After 11:00 the governor was surrounded by some two thousand demonstrators who he feared could storm his palace. What made his situation impossible was that he was he was under the hostile IIIrd Army's ultimatum to hand over the police until 14:00. Instead he activated his last-ditch contingency and escaped the capital, relocating his government to Passo Fundo in the hinterland, arriving at 20:40. There he had the 2nd Police battalion and an Army cavalry squadron. Gathering the northern police, volunteers and fuel he prepared a counteroffensive.
The ultimatum was hollow and the police requisitioning went nowhere as the state prosecutor declared it couldn't be done without a presidential decree.
The situation in the capital was mostly in control, but officers in the 19th Infantry Regiment immobilized their legalist commander before nighttime (probably on the 1st, but it's not very clear). Some legalist sergeants stayed entrenched in a corner ready to fight. In the 6th division pro-Adalberto officers hampered command.

Across the border the Argentine Army raised its alertness level.

In the 1st Cavalry two regiments (1st and 3rd) mutinied.

In all coupist divisions civilian control measures were taken, internal rifts faced and defensive measures taken against the legalists and even, under low information, between each other.

The 2nd Cavalry had to send a platoon to face the 1st Cavalry but the neighboring 1st Cavalry Regiment defected to it. The 5th Cavalry Regiment from Quaraí was moved forward to serve as a reserve. The Alegrete garrison (12th Engineer, 6th Cavalry, 3rd Self-propelled Gun) had to occupy Manoel Viana to secure communications, but had a legalist commander, coupist officers and legalist sergeants. Diplomacy dragged on through the 2nd and the 6th Cavalry was even readied to move against the commander's engineers, but it wasn't needed. Then night on the 2nd a squadron of the 3rd Motorized Cavalry occupied Cacequi, a rail hub and possible site of unionist activity.

In the 3rd Cavalry the 14th Cavalry Regiment remained legalist and the head itself, Bagé, was in conflict. Of the three units (3rd Horse Artillery Regiment, 12th Cavalry Regiment and 3rd Mech Recon Regiment), only in the artillery the commander had a good grip. The division HQ was occupied by legalist sergeants who took the officers hostage, only the commander and his staff weren't there.
So on the 1st of April the artillery neutralized the civilian enemies. On the next day the Mech Recon's sergeants wanted to support those at the HQ but were dissuaded by the artillery's threat. The 12th Cavalry was to move against the HQ but the sergeants mutinied. The task was left to the artillery which would move a gun as a threat. By a mistake the artillery's movement was stopped but the sergeants saw just enough of it to surrender.
Hence Garrastazú didn't consider himself fit to attack the capital and wasn't regarded as a strong force on the coupist side.
