Général Alexandre Percin was a French military officier, chief of staff for Louis André, the Minister of War responsible for the Affaire des Fiches, from 1900 to 1904.

[1] Appreciated during his service in that position, Percin was described by André in 1904 as: "[an officer] generally very intelligent, very vigorous, very active, with a capacity for exceptional work, assiduous and methodical: he wrote well, and with grace."

These qualities were not disputed by Lieutenant Colonel Émile Mayer, who had opportunity to judge Percin because of his friendship with the Minister of War.

Mayer, who well knew the two men, recalled that they were commanded together to Angoulême and that "André had there the opportunity to appreciate his young comrade, of whom he had a high estimation of intelligence, of professional valor, and of moral quality...

Because of his republicanism and his relatives, Percin was considered to be the probable successor to the Minister of War before he quit the cabinet of André in 1904.
