2nd Corps and the 28th Division, established using a walkie-talkie captured from the VRS. After initial distrust on the part of the 28th Division, the Šabić brothers were able to identify each other as they stood on either side of the VRS lines. Early in the morning, the column crossed the asphalt road linking Zvornik with Caparde and headed in the direction of Planinci, leaving a unit of some 100 to 200 armed marchers behind to wait for stragglers. The column reached Križevići later that day, and remained there while an attempt was made to negotiate with local Serb forces for safe passage through the Serb lines into Bosnian government controlled territory. The members of the column were advised to stay where they were, and to allow the Serb forces time to arrange for safe passage. It soon became apparent, though, that the small Serb force deployed in the area was only trying to gain time to organise a further attack on the marchers. In the area of Marčići – Crni Vrh, the VRS armed forces deployed 500 soldiers and policemen in order to stop the split part of the column (about 2,500 people), which was moving from Glodi towards Marčići. At this point, the column's leaders decided to form several small groups of between 100 and 200 persons and send these to reconnoiter the way ahead. Early in the afternoon, the 2nd Corps and the 28th Division of the ARBiH met each other in the village of Potočani. The presidium of Srebrenica were the first to reach Bosnian terrain. Breakthrough at Baljkovica The hillside at Baljkovica () formed the last VRS line separating the column from Bosnian-held territory. The VRS cordon actually consisted of two lines, the first of which presented a front on the Tuzla side against the 2nd Corps and the other a front against the approaching 28th Division. On the evening of 15 July a heavy hailstorm caused the Serb forces to take cover. The column's advance group took advantage of this to attack the Serb rear lines at Baljkovica. During the fighting, the main body of what remained of the column began to move from Krizevici. It reached the area of fighting at about 3 am on Sunday, 16 July. At approximately 05.00 hours on 16 July, the 2nd Corps made its first attempt to break through the VRS cordon from the Bosnian side. The
