There were movements of the paratroopers of the Paratroopers' Regiment, that quickly occupied various air bases, as well as the Air Force General Staff, of the Lisbon Artillery Regiment (RALIS), that, shortly after, set up a military apparel in many places, and the troops of the Practical School of Military Administration (EPAM), that occupied the studios of Rádio e Televisão de Portugal and took control of the tolls on the northern highway.
[1] There is a consensus in Portuguese historiography that the military movements were caused by the exit of the paratroopers, and that, according to its protagonists, the events aren't based in a simple corporate claim.
[1] There's also a lack of consensus in many other matters, which are caused by the lack of response to the question of who ordered the paratroopers to leave: as an example, if it was a state coup or if it was an action done to clarify the political-military situation; how many military plans there were; how to explain the behavior of Otelo Saraiva de Carvalho and those part of the CR, the Portuguese Communist Party's (PCP) behavior, and that of the President Francisco Costa Gomes.
[2] The political, economic, and social crisis in post-Carnation Revolution Portugal, a period known as PREC, and the make-up of The Constituent Assembly, the first democratically elected organ after the fall of the previous regime, gave rise to serious confrontations during what became known as the Hot Summer of 1975.
On this day, dissident paratroopers tried to seize military complexes across the country,[3] in a coup attempt that was easily defeated by commandos loyal to the government.
