The *Araraquara* was not a warship. She was a twin-screw motor ship built at Cantiere Navale Triestino in Monfalcone, on the Italian Adriatic, as yard number 176. Launched on August 1, 1927, completed that October, she joined the Lloyd Nacional fleet - a Brazilian shipping company that worked the long coastal trade between Rio de Janeiro and the northeast. Three sister ships followed her down the ways in the same class, the *Araranguá* first as lead ship. For fifteen years *Araraquara* carried passengers and freight up and down the same ports - São Paulo, Salvador, Aracaju, Recife - ordinary commercial steaming in an ordinary world. In August 1942 that world was no longer ordinary anywhere in the Atlantic, but Brazil was still a neutral country. Captain Augusto Teixeira de Freitas was her master. On August 11 she left Rio de Janeiro. She called at Salvador. On August 15 she sailed north, and she never reached Recife.

Commanded by Harro Schacht, U-507 had slipped into the shipping lanes off Brazil's northeastern coast earlier that month. At 19:12 local time on August 15, she sank the Lloyd Brasileiro passenger ship *Baependi* about twenty nautical miles off the Rio Real lighthouse. *Baependi* went down so fast she could not send a distress call. Two hundred and seventy people died with her. The *Araraquara*, unaware, was less than two hours away and steaming into the same patch of sea. At 21:03 and 21:04 the two torpedoes struck. Over the following day and a half, U-507 would sink four more Brazilian ships - *Aníbal Benévolo*, *Itagiba*, *Araraquara* itself, and *Arará* - killing more than 600 civilians in total. Not soldiers. Families. Passengers returning to the northeast. Merchant crews. Children.

First Officer Milton Fernandes da Silva lived. He wrote a report of what had happened a month after he was pulled from the sea. Twenty-eight people reached shore in a single lifeboat after a long night on the open Atlantic; four more crewmen clung to wreckage through the dark, and one of them, hallucinating, threw himself into the water and was not recovered. The rest survived until daylight. The names of those who did not survive - the hundred and thirty-one - ran in Brazilian newspapers alongside the names from the *Baependi*, the *Itagiba*, the *Arará*. Families in Salvador, in Recife, in Rio read them over coffee. The country's mood changed within hours.

Students, trade unionists, and workers marched through Brazil's capital cities demanding that President Getúlio Vargas act. Crowds gathered outside the Guanabara Palace and the Itamaraty Palace in Rio de Janeiro, calling for a declaration. On August 22, 1942, after a ministerial meeting, Vargas declared a state of belligerence against Germany and Italy. Decree-Law No. 10,358, signed on August 31, made it official. Within two years, a Brazilian Expeditionary Force would fight alongside Allied troops in the Italian campaign - the only South American ground force to see combat in World War II - in a country whose shipyards had built the *Araraquara* fifteen years before. The wreck lies at the position where U-507 took her, in water about twenty nautical miles off the Real River mouth. It is not a tourist dive site. For the families of the 131, it is still, in every meaningful sense, a grave.
