Biography
Alphonse was born on February 10, 1841, in the Basses-Pyrénées department as the son of Alexandre-Louis Dugenne, the editor of the Mémorial des Pyrénées, and was the great-grandson of Elie-François Dugenne.

Bắc Lệ Ambush


On June 23 1884, after the signing of the Tientsin Accord on June 3, Dugenne led a column of 799 French troops towards Langson. He encountered several thousand Chinese troops who opposed his passage. Dugenne sent a parliamentarian bearing a letter announcing that, having no order, he asks the commander of the French column to have one given to him by Peking.

Dugenne revealed that he had orders to go to Langson and that, in three hours, he would continue on his way. At the appointed time, he crossed the Thương River, but was turned back by the Chinese. Forced to make a retreat, he called Captain Maillard to go with his men to stand in the rear. After 2 hours, at 4 o'clock Maillard re-joined the main body, which had recrossed the river and was encamped on the right bank, bringing back a third of his men. When night came, in his rudimentary headquarters and under fire, Dugenne wrote a dispatch to the general-in-chief.

Lieutenant of the Marine Infantry Bailly, in charge of optical telegraphy, was instructed to try, from a hill on the left bank, to warn the French headquarters in Hanoi of the situation of the column. The light caught the attention of the Chinese, who rained a hail of bullets down the hill, but salvo fires made them believe that it was occupied by important forces. As such, the Chinese did not engage, which enabled the volunteers to regain the bulk of the column safe and sound, and continue their retreat in relative safety. The forces then arrived at Cau-son on June 30.

Final Years
Dugenne was later recalled to France in September. He was sent to Formosa (now Republic of China) at the beginning of 1885 and returned to Tonkin. He was appointed colonel in July 1887, he commanded the marching regiment of the French Foreign Legion and the circle of the 11th military region. He returned to France in May 1887, passing his command to Commander Diguet.

He then returned again to Tonkin after a brief visit to France, and died 20 December 1887 during a column of operations between the Thương River and the Cầu River against the Caï Kinh-le, a few kilometres north of Tin-Dao in the territory of Monkayo, from the rupture of an aneurysm. He was buried in Phu Lang Thuong.
