On 9 April 1940, when the Germans invaded Norway, the tank and the three armoured cars were stored in the depot of Dragoon Regiment 1 at Gardermoen. When Dragoon Regiment 1 finished its mobilization at 03:00 on 10 April and moved out to oppose the invading German forces they left both the tank and the armoured cars behind. The tank and the armoured cars were captured by the advancing Germans and disappeared from records, after having been a popular object for souvenir photos for German troops at Gardermoen in May 1940.
