西貢條約
However, the overall Vietnamese military performance was not as successful. On 5 June 1862, the court's plenipotentiary Phan Than Gian and another official Lam Duy Hiep signed the Treaty of Saigon. This agreement ceded the three southern provinces of Gia Định, Dinh Tuong and Biên Hòa to become the French colony of Cochinchina. The treaty was accompanied by financial compensation to France, religious concessions to missionaries and commercial opportunities to European merchants. Nevertheless, Truc continued his resistance in defiance of the treaty. On 15 June 1866, in one attack, he killed five French officers and captured 100 firearms, then returned to Ha Tien where he built up another peasant movement at Cua San.
