His second crossing began in December 1947, at Manwakh well in Yemen. The king of Saudi Arabia did not agree to Thesiger entering his territory, and imprisoned Thesiger and his party when they arrived at Sulayil. Soon released, they travelled to the Liwa Oasis and then to Abu Dhabi town, arriving on 14 March 1948. In April, Thesiger visited the Buraimi Oasis, for which the Iraq Petroleum Company (IPC) held an oil concession, which it operated through an associate company, Petroleum Development Oman. Dick Bird, the company's representative, was concerned by Thesiger's attitude towards oil exploration. Thesiger disapproved of the company's activities, believing that the discovery of oil would destroy the Bedouin way of life. However, the need to finance his expeditions led the explorer to accept funding from the oil company in exchange for providing information garnered from his travels.
