The Léopard

A Chacal-Class Destroyer

The French destroyer Léopard was a distinguished vessel of the Chacal-class, constructed for the French Navy during the 1920s. Named after the eponymous feline, she was designed to counter the formidable Italian Leone-class destroyers, embodying France's naval aspirations in the interwar period.[2]

A Storied Career

Initially serving as a training ship in the mid-1930s, Léopard transitioned to critical convoy escort duties at the onset of World War II. Her operational history is marked by significant engagements, including bombarding advancing German forces and participating in the pivotal Dunkirk evacuation.[9] Following the fall of France, she was seized by British forces and subsequently transferred to the Free French Naval Forces, where she continued her fight against the Axis powers.

Final Voyage and Loss

Under Free French command, Léopard underwent extensive conversion into an escort destroyer, playing a crucial role in anti-submarine warfare and the liberation of the island of La Réunion. Her active service concluded tragically in mid-1943 when she ran aground near Benghazi, ultimately breaking apart in a gale and being declared a total loss.[15] Her legacy includes the prestigious Médaille de la Résistance with rosette, awarded posthumously in 1946.[1]

    • A Type 291 search radar was installed.[13]

Anti-Submarine Warfare

Following her conversion, Léopard proved her mettle in the relentless Battle of the Atlantic, contributing to the crucial effort of neutralizing German U-boat threats.

  • Assigned to convoy escort duties in the Western Approaches.
  • 24 February 1941: Rescued 39 survivors from a British cargo ship.[11]
  • 11 July 1942: While escorting Convoy OS33, Léopard, alongside HMS Spey and HMS Pelican, successfully located and sank the German submarine U-136.[14]
  • 12 July 1942: Collided with the sloop HMS Lowestoft, sustaining damage to her bow, which necessitated repairs in South Africa from September to October.[15]

Liberation of La Réunion

One of Léopard's most notable actions was her role in the liberation of La Réunion, a French island in the Indian Ocean, from Vichy control, a testament to the Free French commitment to reclaiming French territories.

  • Initially selected in June 1942 for the mission to persuade the Vichy government of La Réunion to join the Free French, but her collision delayed the operation.
