TheBinnenlandse Strijdkrachten (BS; English:'Domestic Armed Forces'), fully theNederlandse Binnenlandse Strijdkrachten (NBS), was a government-sanctioned union ofDutch resistance groups during theGerman occupation of the Netherlands inWorld War II, which had hardly cooperated until then.
Until 1944 the resistance groups, insofar as they were in contact, worked independently under the supervision of theBureau Bijzondere Opdrachten (BBO, 'Office of Special Assignments') of theDutch government-in-exile inLondon. When they were merged into theBinnenlandse Strijdkrachten,Prince Bernhard of Lippe-Biesterfeld was appointed commander of this new organization, although he remained in London. The commander of the BS in the occupied Netherlands was ColonelHenri Koot, who was inAmsterdam.
At the time the groups were united, they had less than 10,000 members between them. They were also very poorly armed, though this would improve followingAllied weapon drops.
The full name of the organization was theNederlandse Binnenlandse Strijdkrachten (NBS). The short form of the name was preferred, however, not least because the full abbreviation resembled that of the collaborationistNational Socialist Movement in the Netherlands, the NSB.
The BS was created in the image of theFrench Forces of the Interior and enjoyed great support fromQueen Wilhelmina. The organization was divided intoStoottroepen ('Assault Forces') andBewakingstroepen ('Guard Forces'). In the still occupied part of the Netherlands, theStoottroepen were referred to as theStrijdend Gedeelte der BS (SG; 'Combatant Division of the BS'). The men of theStoottroepen had to come from the armed resistance. TheBewakingstroepen were made up of "those who have made themselves available to maintain or restore order and peace on the day of liberation and thereafter." They would only take to the streets after the liberation. So for the time being they were little more than members-in-waiting.
The BS was founded partly to keep the armed resistance movement manageable, especially now that it would be supplied with weapons on a large scale. The organization was bound by all sorts of rules. For example, members of the BS were only allowed to appear publicly as an army if the commander (Prince Bernhard) gave the signal. The union of the three armed resistance groups also did not mean that those groups were immediately absorbed into the new organization. The differences between them proved too great for that.
Regular top meetings took place between the three groups under the code name "Delta-Center." "Commander Delta" was Colonel Koot. In September 1944, the OD brought in 4,000 men, the LKP 1,800 men, the RVV 1,000 men.
Members of the BS wore blueboilersuits as their uniform.[1][2]
From September 1944 to May 1945, a total of 1,730 members of the organization were killed. The BS experienced tremendous growth from October 1944 on. That great influx started in the liberatedsouthern provinces.
In May 1945 there were 150,000 to 200,000 members of the BS throughout the Netherlands. The entire resistance was estimated to have no more than 25,000 (in 1943) to 45,000 (1944-1945) participants.
Neither theGermans nor the Allies thought highly of the BS. The organization expected to stand "shoulder-to-shoulder" with Allied soldiers to "whip thekrauts", but the Allies concluded an armistice with the Germans on 4 May 1945, which included the condition that only Allied units would disarm the Germans, and not the BS. This effectively made theBinnenlandse Strijdkrachten redundant. The Allies then forbade members of the organization from appearing armed in public, because they feared chaos would break out and BS men wouldlynch Germans. The organization did not comply with this ban, which, according to researchers, has led, among other things, to violence such as the7 May shooting onDam Square in Amsterdam.[3]
The BS originated from the three main resistance groups:
Because there was a post-war shortage of former resistance fighters, many other (young) men without loyalties to any group were also able to join the BS after the war.

TheHerinneringsinsigne Binnenlandse Strijdkrachten 1944-1945 (English:'Domestic Armed Forces Remembrance Badge 1944-1945') was instituted after the war by Prince Bernhard of Lippe-Biesterfeld.
The disorganized or spontaneously organizedBinnenlandse Strijdkrachten meritoriously performed many tasks and as commander of the BS, Prince Bernhard was appointedCommander in theMilitary Order of William, as befits the commander of a victorious army corps. There was no decoration or visible tribute to the men of the BS. They were ineligible for theMobilisation War Cross or theWar Commemorative Cross. TheResistance Memorial Cross would not be established until December 1980. Eligibility for the Mobilisation War Cross only followed when it was reestablished byQueen Beatrix on 1 October 1992.
