This silent WWII German newsreel shows long range German bomber aircraft making strikes against Allied shipping in the Atlantic sea lanes near Ireland. In 1940, these "back door" raids were commonplace and costly to both sides. On one raid in July of that year for example, the Luftwaffe destroyed five ships in one convoy and damaged five other ships and two destroyers while sustaining the loss of 28 aircraft -- some of them shot down in the heavily-guarded English Channel.
