Ironclad protected the timetable for Operation Torch

Operation Ironclad here means the initial seizure of Diego Suarez, while later operations carried the conquest of Madagascar into September and November. The limited landing was designed to remove the urgent threat without tying down ships and troops needed for Operation Torch. Landing vessels approached under the island's shelter and retained escape routes toward South Africa if the strategic situation deteriorated. The main combat ships stayed farther north, where they could support the assault yet still combine with the Eastern Fleet. This positioning balanced amphibious support with readiness to concentrate against a Japanese move into the Indian Ocean.
