Here are also some other points that are maybe worth to put into an event for The Netherlands:
In 1936 the government decided that extra money had to be spend for the army. Also, the troops that normally were finished with their military service had to stay in the army, because of the occupation of the Rhineland by German forces.
The 7th of January 1937 the dutch Crown Princess, Juliana, married with the German Bernard von Lippe Bisterfeld, an event that brought much joy in the country. At the 31st of January of 1938 Juliana gave birth to her first child, princess Beatrix.
After the Anschluss, in 1938, the dutch government made a statement, declaring the absolute neutrality of The Netherlands. At the 3rd of september 1939 again such a statement was issued.
The 28th of august 1939 a mobilization was announced, calling up another 180.000 men, increasing the total army to 280.000 men.
In 1940 the dutch army held a total of 7 divisions, 2 brigades, 1 light division and about 125 airplanes, of which 60 were considered 'modern'. The army also had a couple of Armoured cars, but just a few.
Of course, at the 10th of may, at 3.55 o'clock, Germany started operation Fall Gelb, and four days later, after the bombardment of Rotterdam and the threat to bomb other cities too, The Netherlands surrendered. The Royal Familie fleed to London, together with the government, and also some ships of the navy.
After the attack of Pearl Harbor, the ducth government declared war at Japan.
I hope this helps,
