at the end of April 1942, taking full advantage of the lit-up settlements on the shoreline to pick and choose her targets amongst the unescorted shipping which bottlenecked between Cuba and the Floridan peninsula. Here she sank four large cargo ships in three days before following the coastline along Western Florida and Alabama, where in three more days she sank four more large unprotected ships, making full use of the failure of the local authorities to enforce either convoy regulations or the blackout. On 6 May she sank the about 45 miles south-southeast of the mouth of the

, leaving a shaken seaboard behind her. On this cruise alone she had sunk nine ships totalling 44,782 GRT.
Third patrol
Her third patrol was even more controversial, as a fruitless passage across the Atlantic brought her to the Brazilian coast in mid-August 1942. There she searched for Allied shipping hugging the coastline in Brazilian territorial waters heading for North America. Here she again saw unescorted ships and a lit coastline, and Schacht made the inexplicable decision to attack without first ascertaining the nationalities of her targets. The first was the Brazilian ''Baependy'' on 16 August, which was torpedoed and sunk with 270 civilian lives. A few hours later the ''Araraquara'' was sunk, killing 131 people, followed by the ''Annibal Benevolo'', on which 150 civilians drowned. The next day the slaughter continued, the ''Itagiba'' sunk within sight of the city of
Valença, killing 36, and the ''Arara'' similarly sunk with 20 deaths as she picked up the survivors of the ''Itagiba''. Two days after this, the tiny sailing vessel ''Jacyra'' was sunk, and a Swedish ship was torpedoed three days after that. In just one week, ''U-507'' had sunk seven ships of 18,131 GRT and killed over 600 people, all of them neutral civilians.
Although since February 1942 German and Italian submarines had attacked Brazilian ships, during May Brazilian aero-naval forces began to attack

bases were made available to American naval air squadrons, thus denying the U-boats their previous advantage of hiding in Brazilian coastal waters, and giving the Allies air cover across most of the Southern Atlantic, making the job of the U-boats significantly harder. In addition, Germany's standing amongst neutral nations, particularly the formerly pro-German dictatorships of South America, was in tatters, never to recover.
