French decolonization of Morocco and Tunisia handed the F.L.N. open frontiers

Evidence

But the greatest bonus for the F.L.N. cause, both in terms immediately of arms supplies and later of troop movements, came with France’s granting of independence to Morocco and Tunisia in March 1956, the paths to which had been pioneered by Mendès-France. From then on the F.L.N. had friendly and open frontiers to east and west, of which the Tunisian in particular was to provide benefits of inestimable value. — Horne, Alistair, A Savage War of Peace- Algeria 1954-1962, 404 (#corroborates, via linked claim)

With such an outlay in expenditure and effectives, the integrity of the Morice Line became the top military priority for the French during the winter of 1957–8. Its breaching had equally become the supreme objective for the F.L.N.; there were now some ten thousand A.L.N. troops, armed or in training, concentrated in the frontier zone, and the weapons beginning to flow into Tunisia from all over the world had totalled, over the three winter months, 17,000 rifles, 380 machine-guns, 296 automatic rifles, 190 bazookas, thirty mortars and over 100 million rounds of ammunition. Meanwhile, the Wilayas were asphyxiating for want of reinforcements. — Horne, Alistair, A Savage War of Peace- Algeria 1954-1962, 815 (#expands, via linked claim)
