This week’s research was based on my research question which I narrowed down, with the help of professor Urwin, to focus on the aspect of British air defenses against the Luftwaffe that were orchestrated by Hugh Dowding. These defenses became known as the Dowding system, and included radar and human observers. I focused my research on primary sources, as they are usually harder to come across than secondary sources. Primary sources that I found using the national archives include a couple of letters written by and received by Winston Churchill, who was prime Minister at the time of the battle. These letters give the reader a sense of the nervousness of British leaders during the invasion. You can tell that Churchill was in desperate need of allies, and this will help me as a write my paper because it demonstrates that Britain should not have been able to hold off Germany. I will also use Churchill’s speeches because they demonstrate how he was able to pull the nation together in order to survive the attack by Germany. Other primary sources that are going to be very useful when describing the Dowding system are two separate lectures/speeches from Dowding himself as he describes what his defense methods were. These are clearly useful because they do not require much interpretation but instead describe exactly what I am researching from the man himself who invented the system.
