The German victories at Southhampton and Hastings, allowed German forces to surround and create a ring around London, one similar to Soviet tactics at the First Battle of Stalingrad. The British army could only muster a force of 100,000 mostly inexperienced boys and old men from the home guard to fight against the well armed professional soldiers of the Wehrmacht. Never the less they had the fortune of a American forces of about 40,000 based in London to help in defence of the city. By the time Nazi allied forces entered the city, it was greatly defended and fortified.
The German 7th and 9th armies launched fierce attacks into East London, concentrating on capturing a heavily defended Whitechapel, with strong tank poundings the German routed and then stormed British defensive position throughout the town. Killing many of the young boys, and women in the process.
