4th Division (Netherlands)

The 4th Division () was a major infantry formation of the Royal Netherlands Army. Established in 1905, it is best known for its defense of the southern sector of the Grebbe Line during the German invasion in May 1940.

History

In May 1940, the 4th Division was a key element of the Dutch field army (Veldleger), tasked with holding the crucial Grebbe Line. Subordinated to the II Army Corps, the division faced the primary German thrust towards Utrecht. The formation participated in the pivotal Battle of the Grebbeberg, where it suffered significant casualties before the general Dutch surrender on 14 May 1940.

Organizational and Mobilization Structure

The 4th Division's operational structure in 1940 followed the standard Dutch mobilization model, which relied on three primary combat pillars supported by divisional assets:

• Infantry Core: The division's backbone consisted of the 8th and 19th Infantry Regiments, reinforced by a battalion from the 11th Regiment. These units were composed of reservists mobilized during the "Phony War" period.
• Artillery Support: Fire support was centralized under the 8th Artillery Regiment, providing a mix of field guns and howitzers tailored for static defense of the fortified Grebbe Line positions.
• Mobile Reconnaissance: Tactical reconnaissance and screening were provided by the 4th Half Regiment Hussars, ensuring the division's connection to neighboring sectors.
