On 19 September 1991, the JNA moved extra troops to the area around the city of Mostar, which was publicly protested by the local government. On 20 September 1991, the JNA transferred troops to the front at Vukovar via the Višegrad region of northeastern Bosnia. In response, local Croats and Bosniaks set up barricades and machine-gun posts. They halted a column of 60 JNA tanks but were dispersed by force the following day. More than 1,000 people had to flee the area. This action, nearly seven months before the start of the Bosnian War, caused the first casualties of the Yugoslav Wars in Bosnia. In the first days of October, the JNA attacked and leveled the Croat village of Ravno in eastern Herzegovina, on their way to attack Dubrovnik in southern Croatia.
