👻 The Mosquito Terror: How Two Men and a Radar Detector Broke the German Night Fighter Defense

The Tactical Evolution of RAF 100 Group and the Decisive Shift in the Battle for the Skies Over Germany

I. The Crisis in the Skies: The Dominance of Schräge Musik

By late 1944, the RAF Bomber Command was facing a catastrophic crisis in its strategic bombing campaign against Germany. Despite the massive scale of the raids, particularly during the Battle of Berlin, German night defenses had evolved into a lethal, highly coordinated system, with German night fighters inflicting unsustainable losses.

The Attrition Rate: In October 1944 alone, Bomber Command lost 217 heavy bombers (Lancasters and Halifaxes). This followed earlier devastation, such as the loss of 574 aircraft during the Battle of Berlin.

The Unseen Threat: The primary culprit was the German tactic involving the upward-firing cannon system known as Schräge Musik (“Slanted Music”). German night fighter pilots would merge into the RAF bomber stream from below, position themselves directly under a bomber’s fuselage, and fire their cannons upward. The bomber crew, focused on threats from the rear or level, never saw the attacker, resulting in sudden, catastrophic destruction.

To counter this existential threat, the RAF created No. 100 Group in late 1943. This specialized electronic warfare unit was tasked with a simple, brutal mission: Hunt the hunters. Equipped primarily with the fast, wooden De Havilland Mosquito night fighter, their objective was to use the German night fighters’ own technology against them.

II. The Technological Advantage: Serrate and the Lichtenstein Dilemma

The core of 100 Group’s strategy was the electronic detection device known as Serrate. Serrate was a converted AI Mark IV radar receiver designed to detect the emissions from the German airborne interception radar, the A.I. (Airborne Interception) Lichtenstein set.

The Lichtenstein Problem: German night fighters, primarily the Junkers Ju 88 and Messerschmitt Bf 110, needed their Lichtenstein radar to find Allied bombers in the absolute darkness. This radar broadcasted on frequencies between $490 \text{ and } 600 \text{ Mhz}$.

The Serrate Solution: The Serrate detector was a passive system. It did not transmit; it only listened. It picked up the Lichtenstein transmissions, providing the Mosquito navigator (Flight Lieutenant Bill Skelton) with a bearing (direction) to the German fighter up to $80 \text{ miles}$ away.

This created a tactical dilemma for the Luftwaffe: use radar and be detected by Serrate, or fly blind and miss the bomber stream entirely.

III. The Mission: Infiltrating the Stacking Pattern

On the evening of November 4th, 1944, Squadron Leader Brans Burbridge (pilot) and Bill Skelton (navigator/Serrate operator) took off from RAF Swanington in their Mosquito. Burbridge, a former conscientious objector, held a personal conviction: “I aimed for engines, not cockpits.” Their goal was an intruder patrol over the Ruhr area, anticipating the German scramble to intercept a Bomber Command raid on Bohlen.

The Four Kills in 37 Minutes

The mission immediately yielded success due to Burbridge’s skill and Skelton’s electronic navigation:

First Kill (Ju 88): Skelton’s Serrate detected a contact $4 \text{ miles}$ out. Burbridge closed in unseen, using the Mosquito’s speed and the German fighter’s lack of rearward radar. He aimed a $3 \text{-second burst}$ of the four $20 \text{ mm}$ Hispano cannons at the port engine. Confirmed Kill at 19:06 hours.

Second Kill (Ju 88G): After a brief chase where the German pilot used radar sparingly (an adaptive tactic), Burbridge closed on a newer Ju 88G variant. He repeated the engine shot, causing the starboard wing to erupt in flames. Confirmed Kill at 19:17 hours.

The Insane Tactic: Joining the Formation

The most daring and strategically significant phase began when Skelton detected multiple German contacts (six to eight) converging on the Bonnhangelar airfield—a major night fighter base. The Germans were stacking (orbiting at different heights, separated by $500 \text{ feet}$) to mass their forces for the intercept.

Burbridge made a choice that changed night fighter doctrine: He joined the enemy formation.

The Mosquito, unobserved by the German forward-looking radar, slipped into the clockwise orbital pattern between two enemy contacts.

For 90 seconds, Burbridge and Skelton flew in perfect formation with the hunters.

At 19:28 hours, Burbridge closed on a Messerschmitt Bf 110 (the Luftwaffe‘s primary interceptor), fired a $3 \text{-second burst}$ into the port engine, and watched it spiral away burning. Confirmed Kill at 19:30 hours.

The destruction of the Bf 110 shattered the German formation. Ground control immediately issued warnings: “Intruder in the area. All fighters take evasive action.”

The Final Engagement (Ju 88G)

A final Ju 88, seeing the explosion, turned to engage Burbridge head-on. In a close-range merge at $200 \text{ yards}$, Burbridge unleashed a full, $5 \text{-second burst}$—his entire remaining concentrated fire—into the nose and cockpit of the German fighter. Confirmed Kill at 19:40 hours.

The Mission Tally: Four German night fighters destroyed in $37 \text{ minutes}$ using only $\approx 400 \text{ rounds of ammunition}$.

VI. The Strategic Aftermath and the “Mosquito Terror”

The mission was not just a record-breaker; it was a tactical force multiplier.

Doctrine Change: Within a week, Air Chief Marshal Arthur Harris reviewed the report, and Burbridge and Skelton’s technique of “orbital pattern infiltration” became standard doctrine for 100 Group.

Statistical Shift: In the month following the mission, Bomber Command losses dropped significantly: 152 aircraft lost in November, down from 217 in October. German night fighter effectiveness decreased by $28\%$.

Psychological Warfare: By December, the Germans called the phenomenon “Mosquito Shreck” (Mosquito Terror). Night fighter pilots reported constant fear, particularly during the vulnerable landing approaches, where Mosquitoes would orbit airfields waiting to strike.

The Final Tally: Burbridge and Skelton finished their tour with 21 confirmed victories—the highest scoring British and Commonwealth night fighter partnership of the war, surpassing the record of Group Captain John Cunningham (“Cats Eyes Cunningham”).

The Life-Saving Mathematics:

Assuming each German night fighter averaged six bomber kills per year (the contemporary estimate), the destruction of 21 enemy aircraft meant that Burbridge and Skelton saved approximately $126 \text{ bomber crews}$, translating to an estimated $1,260 \text{ RAF lives}$.

Their partnership proved that electronic warfare and aggressive intruder tactics could paralyze a sophisticated air defense system by forcing the enemy to choose between blindness and detection, forever changing night fighting doctrine.
