刘永福
Berthe de Villers' remarkable victory at Gia Cuc, coupled with Rivière's simultaneous Capture of Nam Định, demoralised the Vietnamese, appreciably raised French prestige in Tonkin, and emboldened French policymakers to shrug off the growing prospects of direct Chinese intervention in Tonkin. Meanwhile, the failure of cooperation between Prince Hoang and Liu Yongfu alarmed the Chinese. The senior Chinese civil mandarin Tang Jingsong (Tang Jingsong) reconciled the two men in April 1883, and persuaded Liu Yongfu to take the field against the French with the Black Flag Army. The result, in May 1883, was the disastrous French defeat at the Battle of Paper Bridge, in which both Rivière and Berthe de Villers were killed.
