Until Brazil if involved in the conflict, the country was remained in the neutrality in order to inside prevent internal bigger conflicts of the domestic territory. Still in this I capitulate tells question of the involved Amaznia in this world-wide conflict. With the conscription of ' ' soldiers of borracha' ' the Brazilian government looked for to cure the problem of dries north-eastern, therefore the northeasterns had been the main man power. Great part of them died of illnesses as malaria or for influence of the atrocities of the forest. The survivors had been in the Amaznia for not having money to pay the trip in return, or because they were become indebted with the seringalistas (owners of the serigais). In the third chapter, the measures will be pointed that will result in the construction of the Air base of Amap: the decree that authorizeed the construction of the base, as well as the dispossessions necessary to establish a North American base in the neighborhoods of the village of Amap. Soon later, the vision will be dealt with the population before the situation, beyond the convivncia between North Americans and the local population; the modifications in the landscape in result of the construction of the base; the progress of the region; the contact of the population with new ways of life, more specifically, other types of foods; the constant tension (or not, as we will see) lived by the local population. Still the actions will be detached military where effective of the base they had acted, as for example, the sinking of the submarines German U-590 and U-662 no longer context of the overturn of the allies in the Second War. Certifications of people will be pointed out who had lived deeply the events. Finally, we will see what the end of the war represented for the people, as if it gave the delivery of the air base for the Brazilian government, the destination of the workers who had come northeast to work in the base, that now, with the deactivation of the base, they had that to look another job, and what it was made to preserve the installations of the base.
