During the Second World War, the Royal Netherlands Motorized Infantry Brigade was a military unit initially formed from approximately 1,500 Dutch troops, including a small group guarding German prisoners-of-war, who arrived in the United Kingdom in May 1940 following the collapse of the Netherlands. Elements of this force became the nucleus of what was originally called the "Dutch Legion."
Veterans of the Princess Irene Brigade who were members of the Dutch Army stationed at Wrottesley Park, Wolverhampton during World War II were given the Freedom of the City of Wolverhampton on 19 August 2006.
Although augmented by conscription from overseas citizens from Canada, the United States, the Middle East, the Dutch West Indies (Netherlands Antilles and Suriname), South Africa and Argentina; the Dutch force grew very slowly as troops were detached for other duties i.e. the Commandos, the Navy etc. While some 500 Surinamese volunteered for service in the brigade, they were rejected by the Dutch government, on the grounds that their racial background might cause offense to volunteers and conscripts from South Africa. (Some Dutch West Indian personnel nevertheless later saw action with the Royal Netherlands East Indies Army in the Pacific theatre.)
On 11 February 1941, by approval of Queen Wilhelmina, the Dutch Legion gained a new name, the Prinses Irene Brigade (P.I.B.).
