Battle of the borders (Algerian war)

Battle context

The Battle of the Borders was a series of French military operations conducted primarily along the Algeria-Tunisia frontier between January and May 1958, targeting ALN forces stationed in Tunisia that were pressing against the Morice Line. The operations pitted French paratrooper units against ALN combatants who were mounting attacks and bombardments on the fortified barrier. With FLN losses recorded at approximately 2,400 against a force estimated between 5,000 and 10,000, the engagements inflicted substantial attrition on the ALN's external contingent. By degrading the cross-border threat, the operations reinforced the Morice Line's function as a strategic barrier separating FLN interior forces from external reinforcement and supply, a central French objective in containing the insurrection during this phase of the war.
