In 1974, the brazilian military regime began a highly secret bombing campaign of tribal settlements belonging to the warimi people located in key areas of the Amazon, largely those above Iron Ore reserves by Paraupebas and those living around the future developing areas around the Transamazon, as an effort to drive them out of those areas.
The regime did not want to simply strike the indios by surprise and without warning, because doing so would be immoral. Unformalized meetings for negotiating resettlement have apparently been made before, with no progress, the government decided instead to deliver an ultimatum, demanding them to peacefully surrender and leave to a different place.
The army airdropped pamphlets like these, stating that the índios where surrounded, that any attempt of resistance was futile, that they were brazilian citizens and therefore should obey the orders given by the government of Brazil, if not, they'd meet serious and tragic consequences.
But the índios didn't know how to read.
