The Tanzanians eventually assigned the 208th Brigade under Brigadier Mwita Marwa, their unit with the most combat experience, to capture Jinja. A total of 4,000 Tanzanian and 1,000 UNLF troops were to partake in
the operation. They were to be accompanied by three Tanzanian
tanks, one
T-54 and two
T-34s. Initially, rumours spread about the UA troops mining the road from Kampala to Jinja as well as the dam, disquieting the TPDF leadership about the operation. However, the UNLF Minister of Energy, Paul Oryema Opobo, was in regular contact with those still working at the dam. He informed the TPDF that the Amin loyalists had not placed any mines, meaning that an operation to capture Jinja could go ahead. The TPDF also decided not to attempt to encircle Jinja, as this could force the local pro-Amin holdouts to engage in a
last stand; by keeping possible routes of retreat open, the garrison would probably flee, allowing the Tanzanians to capture the local infrastructure intact. The combined force was able to requisition numerous vehicles in Kampala when it departed the city on 15 April, but had to share them among different groups of soldiers as it moved down the two-lane road toward Jinja. Intelligence reports indicated that there were few Uganda Army men along the route, easing worries about an ambush. Two days after the TPDF-UNLF advance began, British diplomat
Richard Posnett told the Kampala press that the new Ugandan Minister of Power and Communications,
Akena p'Ojok, had informed him that a team of commandos had secured Owen Falls Dam and was awaiting the arrival of the main force. The report was erroneous, but was quickly spread through the international media, and was even carried in a Tanzanian state-run newspaper,
Daily News. According to p'Ojok, the report was a ploy by the
Save Uganda Movement (SUM) to cause confusion among the local garrison and try to mislead them into abandoning their positions. The
British Broadcasting Corporation broadcast the story over radio, and many residents in the Jinja area, fearful of the Uganda Army soldiers stationed around the city, began heading for the dam in hope of safety. They encountered drunken, violent soldiers manning a roadblock at the dam who killed many of them. Towards the end of the week the TPDF-UNLF force came close to the installation and encountered dozens of battered civilians who had managed to pass by the Uganda Army soldiers. Akena p'Ojok claimed that the story, alongside some guerrilla actions by local SUM members, did also cause more Amin loyalists to leave their positions and flee from Jinja. The TPDF-UNLF advance was relaxed and uneventful; no resistance was encountered during the march, and many soldiers ate
sugar cane and listened to music from looted radios. The column met celebratory crowds in the towns it passed through along the Jinja road, and towards the end of the week hundreds of civilians were tailing the force, socialising with the soldiers, carrying their supplies and weapons, and fetching them water. The civilians that came from Jinja were questioned by Tanzanian intelligence officers about the status of Uganda Army forces in the Jinja area. They offered highly varied accounts of the situation; estimates of the garrison's strength ranged between 200 and 2,000 men, and there were rumors that Amin was still in the city. The Tanzanians were aware of the roadblock at the Owen Falls Dam, but were unsure if there were other troops along the Nile, or if most of Amin's forces had fled further east. There were only two passages across the Nile; a road bridge at the dam, and a railway bridge one kilometre upstream. Tanzanian planners assigned a main force of approximately 3,000 troops to secure Jinja and divided it into different groups to accomplish different tasks. One battalion was to secure the western side of the bridge, while another was then to quickly move across it and capture the eastern side. A third battalion, under Lieutenant Colonel Salim Hassan Boma, was to then proceed across and attack the Eagle Colonel Gaddafi Barracks. Two other battalions were tasked with seizing the rail bridge and waiting on the west bank, ready to flank Uganda Army forces should stiff opposition be put up near the dam. Tanzanian planners were worried that a few hundred soldiers could block their advance at the bridge, but were also afraid that heavy use of artillery would damage the dam and the bridges and create serious problems for the new Ugandan Government. == Battle ==
