THIAROYE-SUR-MER, Senegal — Biram Senghor regularly pays his respects at a military cemetery in Thiaroye, a fishing village near Senegal's capital Dakar, bowing in front of a different grave each time.
The 86-year-old has no way of knowing which grave belongs to his father, M'Bap Senghor, one of the hundreds of West African riflemen who fought for France during World War II but were likely killed on Dec. 1, 1944, by the French army after demanding unpaid wages.
In this cemetery, where they are supposedly buried, all the graves are anonymous and the exact location of the remains is unknown, as is the number of victims. The true scale and circumstances of the killings remain unclear as Senegal commemorates the 80th anniversary of the massacre on Sunday, threatening to reignite smoldering tensions between France and the former colony.
''I have been fighting to get answers for over 80 years,'' says Biram Senghor. ''(French President Emmanuel) Macron cannot do what the other French presidents before him did; France has to repent.''
The West Africans were members of the unit called ''Tirailleurs Sénégalais,'' a corps of colonial infantry in the French Army that fought in both World Wars. According to historians, there were disputes over unpaid wages in the days before the massacre and on Dec. 1, French troops turned on the unarmed African soldiers and shot them dead.
For decades, French authorities tried to minimize what had happened in Thiaroye. Reports by the French military shortly after the massacre determined that 35 West African soldiers were killed in response to a ''mutiny.'' Other reports by the French army mention 70 deaths.
But today, many French and Senegalese historians agree the true death toll is likely in the hundreds, with some speaking of almost 400 African soldiers killed, based on estimates of the number of riflemen present at the camp on the day of the massacre.
On Thursday, Macron officially recognized the events of Thiaroye as a massacre for the first time in a letter to Senegal's President Diomaye Faye, which was seen by The Associated Press.
