ong the coast and were able to detect planes within a fifty-mile radius. Along with radar, the Royal Observer Group watched for German planes through binoculars from the ground. While the ROG spotted the planes from a distance, the radar would record vital information of the incoming squadrons speed and numbers. This information was sent to headquarters where Spitfires and Hurricanes were then promptly alerted and ordered to intercept. While the radar was maintained, Germany never was able to surprise the British Royal Air Force (Hough 27-28). The disadvantages and advantages of each opposing force set the stage for a dramatic and key battle of the Second World War.The Battle of Britains length and its exact events is often the subject of debate.

They attacked the convoys, which carried coal and bulk raw materials, hoping to cripple Britain that had learned to depend on these convoys to sustain its nations economy (Bickers 108). The Germans did not plan on all out victory in Phase one, which began on July 10, 1940....
