Peter Tazelaar (5 May 1920 – 6 June 1993) was a member of the Dutch resistance during World War II and worked as an agent for the SOE.

Birnie introduced his new friend to the Ordedienst which was based in The Hague and headed by Dutch nobleman Joan Schimmelpenninck [nl], who went by the code name of "Uncle Alexander".

Two students from Leiden, Bram van der Stok and Erik Hazelhoff Roelfzema, also escaped to England with Tazelaar.

At one point Tazelaar and his friends communicated with Queen Wilhelmina and her son-in-law Prince Bernhard.

Van der Stok had devised a plan to pick up people in the occupied Netherlands by boat.

He pretended to be a drunk reveller and was able to slip past German sentries guarding the beach by the casino.

At the end of January 1942 he left with midshipman Gerard Dogger via the Van Niftrik escape route [nl] to Switzerland.

The marriage did not last long and Sherston left him for Kas de Graaf, another Dutch resistance member.

A film shot at the time shows him arriving at Gilze-Rijen Air Base with Erik Hazelhoff Roelfzema.

For the next six weeks he assisted the queen while residing with her, her daughter Princess Juliana, and two other adjuncts in her temporary quarters at Anneville near Breda.

Tazelaar joined the military police and was involved in the detection and interrogation of Indonesian freedom fighters.
