On the 22nd of December HMS Mimi and Toutou were launched, and on the 26th they saw their first action with the third German vessel the Kingani which was a 45 ton steamship armed with a six pounder gun. Like the two Royal Navy ships she could only fire forwards. She had been ordered to conduct a reconnaissance on the Belgian side of the lake, to see what the Belgian's were up too. HMS Mimi and HMS Toutou were launched to intercept her. By lucky chance the Kingani sailed past the Royal Navy boats, so they had cut her off from her base. At first Kingani mistook the two motorboats heading towards her as not Belgian, and thus not a threat. Then she spotted the White Ensigns. Turning as tightly as she could to bring her forward gun to bear, the British launches easily evaded the first German shots, and closed to firing distance opening fire about midday. A swirling dogfight on the surface of the lake then ensued, the British quickly realised that Kingani had no rear facing guns and tried to attack from that direction. Eventually a three pounder round hit the gun shield on Kingani and killed three crew including the captain. Several more shell strikes followed, and the German crew struck their colours. In their haste to capture the Kingani HMS Mimi accidentally rammed Kingani at full speed. The damage nearly sunk Mimi, but she managed to ground herself. Kingani was then escorted to port.
