he would leave out the errors. The result should be that contact was aborted immediately. De Bruyne concluded that the agents simply forgot to use the security-checks and even sent messages to remind them. This would tip-off the German intelligence and the agent would be replaced with a German and sent off to a concentration camp. Other intelligence mistakes by De Bruyne included attaching detailed maps of the landing sites at Noordwijk, Scheveningen and Walcherento to the walls of his London office and leaving them up. Observing this, Louis d'Aulnis, an agent of the CID, elected not to announce where his landing place would be beforehand, a measure which ended up saving his life. In their first mission, Peter Tazelaar was to deliver radio equipment and bring two men back from the occupied Netherlands to join the government-in-exile in Britain. Roelfzema had met Tazelaar when the two men had worked as stokers on the St. Cregue during their escape. Roelfzema had often spent time at the seaside resort of Scheveningen and knew that every Friday night a large party was held at the Kurhaus of Scheveningen (Grand Hotel) which had been taken over by the Germans as a headquarters.

In the pre-dawn hours of 23 November 1941, Tazelaar, Roelfzema, Krediet and Lieutenant Francis 'Bob' Goodfellow rowed in on a small dinghy. When they neared the surf, Roelfzema and Tazelaar slipped off the boat and waded onto the beach. Tazelaar was then helped out of his wetsuit to reveal the black tuxedo he was wearing beneath it. Roelfzema then poured a generous amount of brandy over Tazelaar and left him, returning to the dinghy. Reeking of brandy, Tazelaar managed to pass himself off as a drunken party goer and staggered past the sentries stationed around the hotel. Two months later he returned to the beach with three others for a return to England. They were waiting on the beach for Roelfzema but the arrived on the scene first. Tazelaar and one other were able to escape. With no contact to England, he had to return overland, taking his chances traveling through Belgium, France, Switzerland, Spain and Portugal, before reaching England three months later. Roelfzema led fifteen small-boat missions to the shores of the Netherlands. He was in charge of the insertion mission, while a Royal
