Mass arrests recruited replacements for the Algerian resistance's losses. [causal]
If one could draw up a balance-sheet for that first winter of the war in terms of rebel manpower alone, on the debit side the “old guard” had been largely mopped-up; on the credit side there was a plentiful substitution of new recruits resulting from the indiscriminate mass arrests in the cities and overzealous ratissages in the bled. But this remained to some extent a potential, rather than actual, asset.
