Disagreement over tribute and interference in internal affairs arose, eventually leading to the Battle of Al Wajbah in March 1893. Al Bidda fort served as the final point of retreat for Ottoman troops. While they were garrisoned in the fort, their corvette fired indiscriminately at the townspeople, killing a number of civilians. The Ottomans eventually surrendered after Jassim Al Thani's troops cut off the town's water supply. An Ottoman report compiled the same year reported that Al Bidda and Doha had a combined population of 6,000 inhabitants, jointly referring to both towns by the name of 'Katar'. Doha was classified as the eastern section of Katar. The Ottomans held a passive role in Qatar's politics from the 1890s onward until fully relinquishing control during the beginning of the first World War.
