In 1941, the Luftwaffe shifted strategy again. Erich Raeder—commander-in-chief of the Kriegsmarine—had long argued the Luftwaffe should support the German submarine force (U-Bootwaffe) in the Battle of the Atlantic by attacking shipping in the Atlantic Ocean and attacking British ports. Eventually, he convinced Hitler of the need to attack British port facilities. Hitler had been convinced by Raeder that this was the right course of action due to the high success rates of the U-Boat force during this period of the war. Hitler correctly noted that the greatest damage to the British war economy had been done through submarines and air attacks by small numbers of Focke-Wulf Fw 200 naval aircraft. He ordered attacks to be carried out on those targets which were also the target of the Kriegsmarine. This meant that British coastal centres and shipping at sea west of Ireland were the prime targets.

Question: What became the new targets for the Kriegsmarine?
Answer: British coastal centres and shipping at sea west of Ireland

The diversion of heavier bombers to the Balkans meant that the crews and units left behind were asked to fly two or three sorties per night. Bombers were noisy, cold, and vibrated badly. Added to the tension of the mission which exhausted and drained crews, tiredness caught up with and killed many. In one incident on 28/29 April, Peter Stahl of KG 30 was flying on his 50th mission. He fell asleep at the controls of his Ju 88 and woke up to discover the entire crew asleep. He roused them, ensured they took oxygen and Dextro-Energen tablets, then completed the mission.

Question: How many sorties a night were crews asked to fly?
Answer: two or three sorties

Whitehall's disquiet at the failures of the RAF led to the replacement of Dowding (who was already due for retirement) with Sholto Douglas on 25 November. Douglas set about introducing more squadrons and dispersing the few GL sets to create a carpet effect in the southern counties. Still, in February 1941, there remained only seven squadrons with 87 pilots, under half the required strength. The GL carpet was supported by six GCI sets controlling radar-equipped night-fighters. By the height of the Blitz, they were becoming more successful. The number of contacts and combats rose in 1941, from 44 and two in 48 sorties in January 1941, to 204 and 74 in May (643 sorties). But even in May, 67% of the sorties were visual cat's-eye missions. Curiously, while 43% of the contacts in May 1941 were by visual sightings, they accounted for 61% of the combats. Yet when compared with Luftwaffe daylight operations, there was a sharp decline in German losses to 1%. If a vigilant bomber crew could spot the fighter first, they had a decent chance at evading it.

Question: How many pilots remained in February 1941?
Answer: 87 pilots

Five nights later, Birmingham was hit by 369 bombers from KG 54, KG 26, and KG 55. By the end of November, 1,100 bombers were available for night raids. An average of 200 were able to strike per night. This weight of attack went on for two months, with the Luftwaffe dropping 13,900 short tons (12,600 t) of bombs. In November 1940, 6,000 sorties and 23 major attacks (more than 100 tons of bombs dropped) were flown. Two heavy (50 short tons (45 t) of bombs) attacks were also flown. In December, only 11 major and five heavy attacks were made.

Question: December saw how many attacks?
Answer: only 11 major and five heavy attacks

From the German point of view, March 1941 saw an improvement. The Luftwaffe flew 4,000 sorties that month, including 12 major and three heavy attacks. The electronic war intensified but the Luftwaffe flew major inland missions only on moonlit nights. Ports were easier to find and made better targets. To confuse the British, radio silence was observed until the bombs fell. X- and Y-Gerät beams were placed over false targets and switched only at the last minute. Rapid frequency changes were introduced for X-Gerät, whose wider band of frequencies and greater tactical flexibility ensured it remained effective at a time when British selective jamming was degrading the effectiveness of Y-Gerät.

Special units, such as KGr 100, became the Beleuchtergruppe (Firelighter Group), which used incendiaries and high explosive to mark the target area. The tactic was expanded into Feuerleitung (Blaze Control) with the creation of Brandbombenfelder (Incendiary Fields) to mark targets. These were marked out by parachute flares. Then bombers carrying SC 1000 (1,000 kg (2,205 lb)), SC 1400 (1,400 kg (3,086 lb)), and SC 1800 (1,800 kg (3,968 lb)) "Satan" bombs were used to level streets and residential areas. By December, the SC 2500 (2,500 kg (5,512 lb)) "Max" bomb was used.

The Boulton Paul Defiant, despite its poor performance during daylight engagements, was a much better night fighter. It was faster, able to catch the bombers and its configuration of four machine guns in a turret could (much like German night fighters in 1943–1945 with Schräge Musik) engage the unsuspecting German bomber from beneath. Attacks from below offered a larger target, compared to attacking tail-on, as well as a better chance of not being seen by the bomber (so less chance of evasion), as well as greater likelihood of detonating its bombload. In subsequent months a steady number of German bombers would fall to night fighters.

Question: What performed better during night fighting?
Answer: The Boulton Paul Defiant

Question: How could aircraft engage bombers when fitted with a turret?
Answer: engage the unsuspecting German bomber from beneath

The attacks were focused against western ports in March. These attacks produced some breaks in morale, with civil leaders fleeing the cities before the offensive reached its height. But the Luftwaffe's effort eased in the last 10 attacks as seven Kampfgruppen moved to Austria in preparation for the Balkans Campaign in Yugoslavia and Greece. The shortage of bombers caused the OKL to improvise. Some 50 Junkers Ju 87 Stuka dive-bombers and Jabos (fighter-bombers) were used, officially classed as Leichte Kampfflugzeuge ("light bombers") and sometimes called Leichte Kesselringe ("Light Kesselrings"). The defences failed to prevent widespread damage but on some occasions did prevent German bombers concentrating on their targets. On occasion, only one-third of German bombs hit their targets.

German air supremacy at night was also now under threat. British night-fighter operations out over the Channel were proving highly successful. This was not immediately apparent. The Bristol Blenheim F.1 was undergunned, with just four .303 in (7.7 mm) machine guns which struggled to down the Do 17, Ju 88, or Heinkel He 111. Moreover, the Blenheim struggled to reach the speed of the German bombers. Added to the fact an interception relied on visual sighting, a kill was most elusive even in the conditions of a moonlit sky.

The air offensive against the RAF and British industry failed to have the desired effect. More might have been achieved had the OKL exploited their enemy's weak spot, the vulnerability of British sea communications. The Allies did so later when Bomber Command attacked rail communications and the United States Army Air Forces targeted oil, but that would have required an economic-industrial analysis of which the Luftwaffe was incapable. The OKL instead sought clusters of targets that suited the latest policy (which changed frequently), and disputes within the leadership were about tactics rather than strategy. Though militarily ineffective, the Blitz caused enormous damage to Britain's infrastructure and housing stock. It cost around 41,000 lives, and may have injured another 139,000.

Answer: had the OKL exploited their enemy's weak spot

The relieved British began to assess the impact of the Blitz in August 1941, and the RAF Air Staff used the German experience to improve Bomber Command's offensives. They concluded bombers should strike a single target each night and use more incendiaries because they had a greater impact on production than high explosives. They also noted regional production was severely disrupted when city centres were devastated through the loss of administrative offices, utilities and transport. They believed the Luftwaffe had failed in precision attack, and concluded the German example of area attack using incendiaries was the way forward for operations over Germany.

Question: What did the experience of German's using incendiaries mean?
Answer: using incendiaries was the way forward for operations over Germany.

Some writers claim the Air Staff ignored a critical lesson, however: British morale did not break. Targeting German morale, as Bomber Command would do, was no more successful. Aviation strategists dispute that morale was ever a major consideration for Bomber Command. Throughout 1933–39 none of the 16 Western Air Plans drafted mentioned morale as a target. The first three directives in 1940 did not mention civilian populations or morale in any way. Morale was not mentioned until the ninth wartime directive on 21 September 1940. The 10th directive in October 1940 mentioned morale by name. However, industrial cities were only to be targeted if weather denied strikes on Bomber Command's main concern, oil.

From November 1940 – February 1941, the Luftwaffe shifted its strategy and attacked other industrial cities. In particular, the West Midlands were targeted. On the night of 13/14 November, 77 He 111s of Kampfgeschwader 26 (26th Bomber Wing, or KG 26) bombed London while 63 from KG 55 hit Birmingham. The next night, a large force hit Coventry. "Pathfinders" from 12 Kampfgruppe 100 (Bomb Group 100 or KGr 100) led 437 bombers from KG 1, KG 3, KG 26, KG 27, KG 55 and Lehrgeschwader 1 (1st Training Wing, or LG 1) which dropped 394 short tons (357 t) of high explosive, 56 short tons (51 t) of incendiaries, and 127 parachute mines. Other sources say 449 bombers and a total of 530 short tons (480 t) of bombs were dropped. The raid against Coventry was particularly devastating, and led to widespread use of the phrase "to conventrate". Over 10,000 incendiaries were dropped. Around 21 factories were seriously damaged in Coventry, and loss of public utilities stopped work at nine others, disrupting industrial output for several months. Only one bomber was lost, to anti-aircraft fire, despite the RAF flying 125 night sorties. No follow up raids were made, as OKL underestimated the British power of recovery (as Bomber Command would do over Germany from 1943–1945). The Germans were surprised by the success of the attack. The concentration had been achieved by accident. The strategic effect of the raid was a brief 20 percent dip in aircraft production.
