Da Grande Guerra à Ilha Grande: a derradeira tentativa, no pós-guerra, de levar o Novo Arsenal de Marinha para fora da Guanabara

Brazil renewed its fleet with modern warships in the first decade of the 20th Century. However, the country failed to modernize the precarious facilities of the ancient Navy Yard, whose workshops were squeezed in the central area of Rio de Janeiro and also dispersed in caos throughout Baía de Guanabara (Guanabara Bay). The Navy was divided between the advocates of new facilities to be built on Ilha das Cobras (Cobras Island), near the main workshops of the old Yard, and the supporters of a big industrial and military structure to be erected at Baía da Ilha Grande (Ilha Grande Bay), far from the Federal Capital. This article addresses their dispute, decisions, actions and conter-actions, before, during and after the First World War. It’s main subject is the last attempt from the advocates of Baía da Ilha Grande, made after the war, which came closer to succeed before failing at the end of 1922.
