In 2000, during the Second Congo War, government forces suffered a major defeat by Rwandan forces at Pweto, at the source of the river. The DRC forces had brought most of their armored vehicles across the river. There was a single ferry, and they did not have enough time to evacuate the vehicles before the Rwandans arrived. Soldiers loaded a T-62 tank awkwardly, and the ferry tipped over and sank. The Rwandans found 33 tanks, as well as other vehicles, which the DRC troops had tried to burn.
