Wozdwizhenskaya Fortress (1742) on the Sakmara River was the second fort built as a part of Sakmara Distance by Ivan Neplyuyev during his governance of the Orenburg Commission. It was located on the Sakmara River, southeast of Orenburg, 100 miles (160 km) west of Orsk and 30 miles (48 km) north of Werneozernaya Fortress. It was built for protection against raids of nomadic Kyrgyz tribes for capturing of slaves from the Russian frontiers on the Caspian Sea and slave trading to Khiva.
