Friedrich Markworth began his naval career in April 1934. He served on the light cruiser Königsberg and the cruiser Blücher before transferring to the U-boat force in July 1940. He made two patrols on U-103 as I WO. In June 1942 he took over the very successful U-66, one of the five Drumbeat boats, from Korvkpt. Richard Zapp.
On his first patrol with U-66 he sank nine ships for a total of 48,896 tons, mostly in Caribbean waters. He also laid mines at Port Castries on Santa Lucia on 20 July, 1942, resulting in the sinking of three small Allied warships two weeks later.
During his third patrol Markworth was severely wounded when U-66 was attacked on 3 Aug, 1943 by aircraft from the US escort carrier USS Card. On 6 Aug, 1943 U-66 met the oil supply U-boat U-117 and U-117's WO Oblt. Frerks took command for the wounded Markworth and brought U-66 back to base. U-117 herself was sunk while U-66 was at her side (Niestlé, 1998).
Kptlt. Markworth left the U-66 and in October 1943 became a training officer in the 23rd flotilla. In March 1945 he moved to the 25th flotilla.
