On 14 October, the Israelis repelled a renewed Egyptian attack, and the following day launched their counteroffensive. On 16 October the Israelis crossed the Suez Canal[citation needed] and attempted to capture the towns of Ismailia and Suez and to cut off Egyptian supply lines. The Israelis failed to capture either town, but succeeded on 24 October in cutting off the supply lines of the Egyptian Third Army to the south after breaking for a few hours a United Nations ceasefire resolution.
