Summary

[edit]
Description
English: A diagram of "Raspberry", a tactic used in World War 2 by Allied escort ships to defend merchant convoys from German submarine attacks. This diagram is based on a diagram in Captain Gilbert Roberts R.N. and the Anti-U-Boat School by Mark Williams, p. 96.
  1. Under the cover of night, a U-boat sneaks into the convoy and torpedoes a merchant ship.
  2. The U-boat dives and turns around to escape from astern. The escort ships to the rear and the flanks of the convoy fall back to form a line behind the convoy.
  3. The line of escort ships trawl for the U-boat using sonar, and release depth charges when they find it.
Français : Schéma de la tactique en « Framboise » (Raspberry), utilisée pendant la Seconde Guerre mondiale par les navires d'escorte alliés pour défendre les convois marchands contre les attaques des sous-marins allemands. Basé sur un schéma extrait de Williams, Mark (1979) Captain Gilbert Roberts R.N. and the Anti-U-Boat School, London: Cassell, p. 96 ISBN: 9780304303861. OCLC: 925101911.
  1. Sous le couvert de la nuit, un U-boot se faufile dans le convoi et torpille un navire marchand.
  2. Le U-boot plonge et fait demi-tour pour s'échapper par l'arrière. Les navires d'escorte à l'arrière et sur les flancs du convoi se replient pour former une ligne derrière le convoi.
  3. Les escorteurs traquent le U-boot à l'aide d'un sonar et larguent des grenades sous-marines lorsqu'ils le trouvent.
