Returning from the airport, Darcy Ribeiro noted two things: the lights were on at Congress and the Army was defending it. Though there was no quorum for an impeachment, the Legislative conducted an institutional coup d'état by declaring the Presidency vacant - even though during the session an official notice that the President was still on national territory and merely moving to Porto Alegre was read. Darcy fruitlessly tried to mobilize the remaining legalist officers to prevent Ranieri Mazzili, President of the Chamber of Deputies, to assume the post. They couldn't blockade the palace or even pull off something as fickle as cutting off electricity. Mazzili was sworn in at 03:45 on the 2nd, in farcical circumstances. To top it off Darcy and Fico were in the palace as it happened, leading to a discussion about Fico's loyalty; he'd been obeying both Darcy and Costa e Silva, and the former caught Fico calling the latter "my chief" in a telegram. He called him a "treasonous monkey". 

Meira Mattos made extensive further use of airlifts and at morning on the 2nd landed on Brasília itself, with some of his troops soon after. Others took a week to arrive by road. The 10th Police Battalion arrived on the same day. In this picture Georgino is to the left, holding his helmet.

It began its trajectory still expecting combat but halfway through it became just an administrative march. At the São Marcos they found remnants of the AA positions, and interestingly enough there is one mention that they saw the retreating tanks on one moment in the way, at some unremembered river line.
