Career Gysae joined the Reichsmarine in 1931 and served on torpedo boats before transferring to the U-Bootwaffe ("U-boat force") in April 1940. In October 1940 he was appointed commander of the Type VIIC U-boat U-98, unusually without serving any time as either 1.WO (1. Wachoffizier, "1st Watch Officer") or Kommandantenschüler ("Commander-in-Training") on any other U-boats. After six patrols in the north Atlantic in command of U-98, in March 1942 he transferred to the Type IXD2 U-boat U-177 for another two patrols, this time operating off South Africa and Portuguese East Africa.

On 28 November 1942 off the coast of Natal Province, Gysae sank the 6,796 ton British troop ship with three torpedoes. She was carrying 780 Italians; a mixture of prisoners of war and civilian internees. Gysae rescued two survivors to identify the ship, who turned out to be Italian merchant sailors. Mindful of the Laconia Order issued two months previously, Gysae radioed the BdU, who ordered him to continue his patrol. The BdU notified the Portuguese authorities, who sent the frigate NRP Afonso de Albuquerque from Lourenço Marques to help. Of 1,052 people from the Nova Scotia only 194 survived: 192 rescued by the frigate and two others in subsequent days. 858 were killed, including 650 Italians.
