On April 19, a group of 19 commandos under Major
Anders Lassen sailed from their hideout in Balisu bay,
Turkey aboard two
schooners. After a three-day voyage that included intermediate stops in
Syrna and
Anydros, the group landed on an easterly beach near Cape Columbo on the night of 22/23 April. They marched towards the village of
Vourvoulos and after contacting the locals, hid in a nearby cave. The two schooners sought shelter in the nearby
Christiana islands, south-west of Santorini. One member of the group of commandos was the Greek Lieutenant Stefanos Kazoulis (). On April 23, Kazoulis was guided by locals to the capital,
Fira, to gather intelligence. Based on Kazoulis' information, Lassen decided to divide his forces into three detachments. The first would attack the barracks in Fira, the second would head to the residence of the German commanding officer (Lieutenant Hesse) in Fira and attempt to capture him while the third would target the radio station in
Imerovigli. This radio had a long range and served as a
relay supporting communications between
Athens and
Crete. Zero hour for the attack was set to 00:45 of April 24 and the three detachments were led to their targets by local guides. The barracks were located in the centre of Fira, on the second floor of a building that housed a bank. The attackers came from two directions and in spite of barking dogs, they managed to surprise the 40-strong garrison and kill most of them. During the attack, Kazoulis was shot in the chest and died immediately. Sergeant Frank Kingston was also shot in the abdomen and succumbed to his wounds a few hours later. The attack against the German commanding officer failed and he and a few others managed to flee unscathed. The building housing the radio installation was blown up with time bombs. The commandos escaped using their two schooners, taking with them some of the locals who had helped them. ==Reprisals==
