Zohra Drif steeled herself by recalling the Rue de Thèbes bombing.

Evidence

Her target was the Milk-Bar, on the corner of Place Bugeaud, across from Salan’s 10th Region headquarters. It was a particularly popular spot for pieds noirs on their way home from the beach, and on that Sunday it was filled with children and their mothers. Looking at the young faces sipping their milk shakes, Zohra Drif suffered a moment of revulsion at her task, but steeled herself by recalling Yacef’s account of the Rue de Thèbes, pushed her beach-bag under the table, paid, and left at exactly 18.20 hours. — Horne, Alistair, A Savage War of Peace- Algeria 1954-1962, 558
