Faber was working for the Dutch postal servicePTT in 1943 when he came into contact with the Dutch resistance movement through relatives of his fiancee. He joined the resistance and was tasked with carrying a map to London showing the German defenses along the Scheldt estuary. Faber successfully managed to find his way to London by way of Paris and Spain.
Battle of Arnhem
After Faber had been checked and approved by the Dutch and British secret service, he joined a group of Dutchmen being trained for Operation Jedburgh, which involved secret agents being parachuted behind enemy lines to conduct sabotage and guerrilla actions and organize local resistance groups. Faber received training in the Scottish Highlands as a communications specialist, and was also trained in parachute jumping, first from balloons and then from planes. He completed his training with the rank of sergeant. Shortly after, on 17 September 1944, Faber landed near Son as the radio operator of Jedburgh teamDaniel II. He used the assumed name of Lodewijck Fokker for this mission. Faber was in charge of maintaining the radio communications of the American101st Airborne Division during the Battle of Arnhem. However, the radio equipment was lost during the landing. Following the Allied defeat at Arnhem, Faber returned to London by way of Brussels.
In November 1944, Lykele Faber and Peter Tazelaar were dropped by parachute near Haskerhorne in the Dutch province of Friesland as an agent for the Dutch intelligence agencyBureau Bijzondere Opdrachten. Their mission, codenamed Necking, was to maintain radio contact with London, organize the Frisian resistance and help set up drop locations to supply the resistance fighters with arms and ammunition. Faber and Tazelaar installed themselves with radio equipment onboard a yacht hidden in the reed along the edges of the Lytse Wiid and Nannewiid lakes. In March 1945, Faber and Tazelaar were discovered by German troops, and their boat was sunk. However, they managed to escape arrest. Faber and Tazelaar remained in Friesland until the end of the war, joined for some time by stranded British radio operator Alfred C. Springate. On 21 April, they were liberated by Canadian troops. Faber and Tazelaar's boat is now on display at the Fries Verzetsmuseum in Leeuwarden.
Post-World War II
After the end of the war, Faber was temporarily awarded the rank of reserve first lieutenant for general service. Faber emigrated to Canada and settled in Vernon, British Columbia, where he died in 2009 at the age of 90.
