Van Dyke was one of the men in the Dutch Resistance group along with De Leeuw, Goriss, Janssen, Smits and Van de Berg. They saved James Doyle after his B-17 Flying Fortress had been shot down over the Netherlands, their leader being Major Ingram (it is unclear whether Ingram was already a commanding officer of the SAS by the time of this mission). After Doyle joined their group, they continued their raid in order to blow up a train bridge, vital to the German war effort. However, he was shot by a German soldier while making his way to the bridge. He is never mentioned in the game again.
