De Lisle Commando Carbine

Silenced small caliber Rifle

weapon (ranged)

The De Lisle carbine or De Lisle Commando carbine was a British carbine used during World War II. The primary feature of the De Lisle was its very effective suppressor which made it extremely quiet in action.

Designed William De Lisle. It was based on a Short, Magazine, Lee-Enfield Mk III* converted to .45 ACP by modifying the receiver, altering the bolt/bolthead, replacing the barrel with a modified Thompson submachine gun barrel, and using modified magazines from the M1911 pistol. The primary feature of the De Lisle was its extremely effective suppressor, which made it very quiet in action. So quiet, in fact, that working the bolt to chamber the next round makes a louder noise than firing a round.The De Lisle carbine was used by the British Commandos and other special forces. It was accurate to 250 metres (820 ft).

The suppressor, 2 inches (5.1 cm) in diameter, went all the way from the back of the barrel to well beyond the muzzle (the suppressor makes up half the overall length of the rifle), providing a very large volume of space to contain the gases produced by firing. This large volume was one of the keys to the effectiveness of the suppressor. The Lee-Enfield bolt was modified to feed the .45 ACP rounds, and the Lee-Enfield’s magazine assembly was replaced with a new assembly that held a modified M1911 magazine. Because the cartridge was subsonic, the carbine was extremely quiet, possibly one of the quietest firearms ever made.


Porter Lawcewicz first encountered the De Lisle Commando Carbine while on a joint training operation with elements of the British SAS in preparation for Operation Husky off of Tunisia. Learning to make use of the British Folbot sea kayaks, Porter was paired with a commando named Winters, who originally carried this particular De Lisle, and who bragged quite proudly of the weapon’s inherent finesse. In the subsequent months, joint teams would kayak to the shores of Sicily and scout out the various beaches under cover of darkness. It was on one of these scouting forays that Winters mis-stepped in the darkness and badly wrenched his ankle. Unable to retreat quickly enough, Porter and Winters were cut off from their means of egress and forced to lay low. Eventually, Porter took the De Lisle and went to scout out a path by which he could carry his comrade – but upon returning discovered that a German K-9 unit had discovered Winters. Knowing that Winters’ capture would jeopardize the mission, Porter stalked the Germans and eventually set up a KZ where he was able to pick off the small squad of Germans (and the dog) systematically before they had time to notice or react. Porter then buried the bodies and carried Winters back to the Folbot where they made their egress 24 hours late.

Neither Porter nor Winters filed an official report of the incident, but when their time working together was completed, Winters gifted the De Lisle to Porter in thanks. Porter has done his homework and knows how few of these guns are in existence, and cherishes it not only for its rarity, but for its effectiveness and sentimental value.

In the month of preparation prior to Operation Undertow, Porter requested that Sergeant Borkowsky not only give the weapon a once-over tuning, but also that he fit it with the same scope that Porter is familiar with on his M1C. Despite Borkowski’s questioning why anyone would need a scope for such a short ranged weapon, he complied with Porter’s wishes.
