The Danes at Demyansk: 100 Casualties and a Doomed SS Mission
Led by a Danish aristocrat and backed by the SS, the Free Corps Denmark entered the frozen hell of the Demyansk Pocket in 1942—only to find themselves facing relentless Soviet resistance. What began as a mission to stop a small bridgehead spiraled into a series of costly and chaotic assaults. Commanders were killed one after another. Over 100 Danes were lost in house-to-house battles, failed river crossings, and desperate last stands. Despite their determination, the Soviets held the line—and the Danes paid dearly. This is the forgotten story of Denmark’s doomed SS legion on the Eastern Front.
Sjogren Rifle & Shotgun
The Sjorgen rifle and shotgun designs definitely fit the description of Forgotten Weapons. Developed in Sweden, the Sjogren system used a fixed barrel and recoil-operated action in both a 12 gauge shotgun and .30 caliber military-style rifle. It was claimed to have very light recoil, as a result of the energy absorbed by the action cycling, though this recoil reduction was likely no more significant than today’s autoloading firearms.
Most recoil operated firearms function by having the barrel reciprocate backwards when fired, but the Sjogren system is different. It has a locking block connected to the firing pin, which keeps the bolt assembly locked in place as long as the firing pin is in the forward (fired) position. When a shell is discharged, the recoil energy must first push the firing pin backwards against its spring. This re-cocks the firing pin and also unlocks the barrel. By this time chamber pressure has dropped to a safe level, and the remaining recoil force can push the bolt back to eject the fired case and load a fresh one.
The Sjogren .30 caliber military rifle was submitted to British Army trials, but failed to garner enough interest to see further testing or use (the sample rifle tested currently resides in the British Pattern Room collection). The shotguns saw some commercial sales, and can still be found today from time to time, but were not successful enough to stay in production very long. Not much information is available on the guns, but we do have a copy of an article describing them in some technical detail from a 1908 edition of Engineering magazine.
A complete work of fiction a pioneer or engineer unit armed with Sjogren shotguns and rifles. Like many units in Enlisted (Cough China/US Cough) its a fun way to add a rare advanced gun. Id love to see a unit more dressed in a Dutch uniform rather than just another German Axis uniform.
I love engineers but rarely use a dedicated engineer squad. I also do not often used shotguns unless i have a second gun like an smg. An event engineer squad with shotguns and rifles could be trucks of fun. also having a event squad this squad could slot into would be even more fun then that.
adding slugs to the buck shot or even fléchettes would make shotguns even more playable in the current meta. id love to see more axis and allied minor powers represented. would love to see shotguns at br3 but given the lack of removable magazine shotguns of the era that seems unlikely.
