Passage: On 30 July 1883 Admiral Courbet, General Bouët and François-Jules Harmand, the recently appointed French civil commissioner-general for Tonkin, held a council of war at Haiphong.  The three men agreed that Bouët should launch an offensive against the Black Flag Army in its positions around Phu Hoai on the Day River as soon as possible. They also noted that the Court of Huế was covertly aiding and abetting Liu Yongfu's Black Flag Army, and that Prince Hoàng was still in arms against the French at Nam Định. They therefore decided, largely on Harmand's urging, to recommend to the French government a strike against the Vietnamese defences of Huế, followed by an ultimatum requiring the Vietnamese to accept a French protectorate over Tonkin or face immediate attack.The proposal was approved by the navy ministry on 11 August, and on 18 August several warships of Courbet's Tonkin Coasts naval division bombarded the Thuận An forts at the entrance to the Huế River.  On 20 August, in the Battle of Thuận An, two companies of French marine infantry and the landing companies of three French warships went ashore and stormed the forts under heavy fire.  During the afternoon the gunboats Lynx and Vipère forced a barrage at the entrance to the River of Perfumes, enabling the French to attack Huế directly if they chose.
