During the Blitz the Luftwaffe suffered from major problems of strategy, as their command (Goering and Hitler) ordered so many targets and constantly changed targets that effort was seriously dispersed. Concentration was never achieved to the levels that the RAF and USAAF ever achieved, not due to lack of airplanes (they they were smaller than their enemies' aircrafts), but due to dispersal of effort, i.e. trying to hit everything at once.

What if they concentrated their night bombing in October-December against London, putting into the bombing 1000+ aircraft (not just bombers, but also fighter-bombers (bf110, me109), dive bombers, sea planes, bomb carrying transports like the Ju52, etc.) over London, which was only 100 miles from Calais, which would allow for maximum bomb loads for most aircraft.
That means 2 tons for the He 111, 2.5 tons for the Ju88 in 1940, 1/2 ton for the Ju87, 1/2 ton for Me109, 1 ton for Bf110 and so on.

Its then conceivable and probable that over 1200 tons of bombs/incendiaries could be dropped on London.
The weather conditions in October-December were conducive to a firestorm like that visited on Hamburg.

Sir Arthur Harris, the officer commanding RAF Bomber Command from 1942 through to the end of the war in Europe, pointed in his post war analysis, although many attempts were made to create deliberate man made firestorms during World War II few attempts succeed:

"The Germans again and again missed their chance, ... of setting our cities ablaze by a concentrated attack. Coventry was adequately concentrated in point of space, but all the same there was little concentration in point of time, and nothing like the fire tornadoes of Hamburg or Dresden ever occurred in this country. But they did do us enough damage to teach us the principle of concentration, the principle of starting so many fires at the same time that no fire fighting services, however efficiently and quickly they were reinforced by the fire brigades of other towns could get them under control."

The raid that began on the evening of 14 November 1940 was the most severe to hit Coventry during the war. It was carried out by 515 German bombers, from Luftflotte 3 and from the pathfinders of Kampfgruppe 100. The attack, code-named Operation Mondscheinsonate (Moonlight Sonata), was intended to destroy Coventry's factories and industrial infrastructure, although it was clear that damage to the rest of the city, including monuments and residential areas, would be considerable.

The first wave of follow-up bombers dropped high explosive bombs, knocking out the utilities (the water supply, electricity network and gas mains) and cratering the roads, making it difficult for the fire engines to reach fires started by the follow-up waves of bombers. The follow-up waves dropped a combination of high explosive and incendiary bombs. There were two types of incendiary bomb: those made of magnesium and those made of petroleum. The high explosive bombs and the larger air-mines were not only designed to hamper the Coventry fire brigade, they were also intended to damage roofs, making it easier for the incendiary bombs to fall into buildings and ignite them

Coventry's air defences consisted of twenty four 3.7 inch AA guns and twelve 40mm Bofors. Over 6,700 rounds were fired. However only one German bomber was shot down.[20]
In one night, more than 4,000 homes in Coventry were destroyed and around two-thirds of the city's buildings were damaged. The raid was heavily concentrated on the city centre, most of which was destroyed. Two hospitals, two churches and a police station were also among the damaged buildings.[21].[22] Around one third of the city's factories were completely destroyed or severely damaged, another third were badly damaged, and the rest suffered slight damage.

The raid reached such a new level of destruction that Joseph Goebbels later used the term Coventriert ("Coventrated") when describing similar levels of destruction of other enemy towns. During the raid, the Germans dropped about 500 tonnes of high explosives, including 50 parachute air-mines, of which 20 were incendiary petroleum mines, and 36,000 incendiary bombs.[25]

The raid of 14 November combined several innovations which influenced all future strategic bomber raids during the war.[26] These were:

-The use of pathfinder aircraft with electronic aids to navigate, to mark the targets before the main bomber raid.

-The use of high explosive bombs and air-mines (blockbuster bombs) coupled with thousands of incendiary bombs intended to set the city ablaze in a firestorm.

In the Allied raids later in the war, 500 or more heavy four-engine bombers all delivered their 3,000–6,000 pound bomb loads in a concentrated wave lasting only a few minutes. But at Coventry, the German twin-engined bombers carried smaller bomb loads (2,000–4,000 lb), and attacked in smaller multiple waves. Each bomber flew several sorties over the target, returning to base in France to rearm. Thus the attack was spread over several hours, and there were lulls in the raid when fire fighters and rescuers could reorganise and evacuate civilians.[27] As Arthur Harris, commander of RAF Bomber Command, wrote after the war "Coventry was adequately concentrated in point of space [to start a firestorm], but all the same there was little concentration in point of time".[28]


The London raid of December shows what could have been achieved:
http://www.historylearningsite.co.uk/impact_blitz_london.htm
On December 29th 1940 Hitler ordered a massive raid on London. The date chosen was deliberate. The River Thames was at its lowest. 100,000 incendiary bombs were dropped and fire fighters in the City area of London had to cope with temperatures in excess of 800 degrees Centigrade. A severed main water pipe did not help the fire fighters. What water the Thames could provide was used but it required fire fighters to crawl across mud banks to simply get to the water. Historian Juliet Gardner simply referred to December 29th as “a dreadful night”.

http://en.wikipedia.org/wiki/Second_Great_Fire_of_London
The "Second Great Fire of London" is a name used at the time to refer to one of the most destructive air raids of the London Blitz, over the night of 29/30 December 1940. Between 6pm and 6am the next day, more than 24,000 high explosive bombs and 100,000 incendiary bombs were dropped.[1] The raid and the subsequent fire destroyed many Livery Halls and gutted the medieval Great Hall of the City's Guildhall.

The largest continuous area of Blitz destruction anywhere in Britain occurred on this night, stretching south from Islington to the very edge of St Paul's Churchyard. The area destroyed was greater than that of the Great Fire of London in 1666. The raid was timed to coincide with a particularly low tide on the River Thames, making water difficult to obtain for fire fighting. Over 1500 fires were started, with many joining up to form three major conflagrations which in turn caused a firestorm that spread the flames further, towards St Paul's Cathedral.

http://en.wikipedia.org/wiki/The_Blitz#Night_attacks
Probably the most devastating strike occurred on the evening of 29 December, when German aircraft attacked the City of London itself with incendiary and high explosive bombs, causing a firestorm that has been called the Second Great Fire of London.[102] The first group to use these incendiaries was Kampfgruppe 100 which despatched 10 "pathfinder" He 111s. At 18:17, it released the first of 10,000 fire bombs, eventually amounting to 300 dropped per minute.[103] Altogether, 130 German bombers destroyed the historical centre of London.

During the December 29th raid only 130 bombers achieved a mini-firestorm.

What if in the October-December timeframe the Luftwaffe manages to start a firestorm in London?
How much damage would/could be wrought? What are the political effects? Could London "take it" like Churchill thought?
