The SMS Königsberg, which has been based in the Rufiji delta is sunk by the British Navy. The British had known it was based at a place called Salale, information gained from intercepted signals, but the town was not marked on any Royal Navy maps! Once her berth was discovered, however, she was kept under observation. An attempt to bomb her with aircraft of the Royal Naval Air Service failed - she was too well hidden beneath overhanging trees. Eventually two Royal Naval monitors followed her up river, and aided by aerial observers, sank her with a bombardment.
