In The Hague also the five DAF M39s were present, two of them without main armament, that had not been used in the "Depotdetachement Bewakingstroepen Cavalerie". In the morning of 10 May these vehicles had been readied and then moved to the headquarters of the Commander Fortress Holland. In the subsequent days they had remained in the city, sometimes patrolling the streets or responding to the many false alarms about presumed Fifth Column activities. In one incident, on 11 May, a M39 had set fire to some railway wagons where, probably groundlessly, German paratroopers were suspected to have hidden.
