During Operation IroncladD'Entrecasteaux fought against the entire British Fleet involved in the landing operations for 36 hours, before finally being damaged and beached. While the other French surface ship, the armed merchant cruiserMS Bougainville,[1] was destroyed along with three submarines during the initial attacks, D'Entrecasteaux managed to dodge torpedoes and escape from the harbour at Diego Suarez.
The sloop managed to avoid damage from various bomb and torpedo attacks and continued to fight throughout the day. She escaped destruction because her shallow draft allowed her to see the torpedoes pass by underneath.
The British battleship HMS Ramillies fired a few salvoes at her with no effect. However, on 6 May 1942, she was finally damaged during another Swordfish attack. The ship started to slowly take on water and was beached before she could sink. An officer and 15 sailors were killed during the attacks.
