He was held by the authorities in Beirut until 1937. Shallash commanded another uprising against the French in Deir ez-Zor in support of the Rashid Ali coup in Baghdad in 1941. However, the revolt was put down, and Shallash was captured. He was jailed in Beirut again, and released in 1946, the year Syria became independent. Shallash also died that year. A biography of Shallash, "Ramadan al-Shallash: Ahad Abtal al-Tarikh al-Arabi" [Ramadan Shallash: A Hero of Arab History], written by Fa'iz al-Shallash was published in Cairo in 2001.
