The home front was secured by the state government and police to ensure months of war fighting ability and prevent any political mobilization by the "internal enemy". It consisted of:

-Sending an emissary to Espírito Santo in the morning, which guaranteed the state's support
-Telephone calls to other governors. Goiás and Mato Grosso could be counted on.
-Rationing fuel supplies.
-Accepting volunteers, 10 thousand showed up. Existing right-wing militias were to be put to use.
-Shutting off the borders.
-Heavy police coverage of sensitive points, all surveyed in advace.
-Shutting off bus traffic between the capital and hinterland. At morning policemen with machine guns and hand grenades occupied the bus station, returned tickets to passengers and requisitioned 108 buses.
-At least 50 arrests of leftists and unionist figures. The Labor Secretary resigned in protest.
-Total control of communications and the press.

Note the similarities with São Paulo's mobilization, but in this case there is little mention of the private sector springing to help on its own initiative.

The police was brought into the field. An infantry battalion's "wartime" formation was:
x3 company of fusiliers, 170 men each
x1 machine gun company, 134 men
Battalions were formed into detachments. Besides the mixed army/police formations sent to Rio (Tiradentes) and Brasília (Caicó) they were:

Triângulo Detachment
4th Battalion
12th Battalion
Would defend against legalists coming from Goiás and hence technically part of the Brasília theater.

Eastern Detachment
6th Battalion
11th Battalion
Would secure the rail line to the port in Vitória. If it sprung into action it'd logically join up with the Espírito Santo police and the 3rd Caçadores Battalion and maybe even elements to the north.

Southern Detachment
8th Battalion
Redeployed to Belo Horizonte.

Belo Horizonte Detachment
Instruction Department
Auxiliary Service Corps
Cavalry Regiment
3rd Battalion
5th Battalion
7th Battalion
