On the evening of December 29, 1940, London suffers its most devastating air raid when Germans firebomb the city. Hundreds of fires caused by the exploding bombs engulfed areas of London, but firefighters showed a valiant indifference to the bombs falling around them and saved much of the city from destruction. The next day, a newspaper photo of St. Paul’s Cathedral standing undamaged amid the smoke and flames seemed to symbolize the capital’s unconquerable spirit during the Battle of Britain.
In May and June 1940, Holland, Belgium, Norway, and France fell one by one to the German Wehrmacht, leaving Great Britain alone in its resistance against Nazi leader Adolf Hitler’s plans for world domination. The British Expeditionary Force escaped the continent with an impromptu evacuation from Dunkirk, but they left behind the tanks and artillery needed to defend their homeland against invasion. With British air and land forces outnumbered by their German counterparts, and U.S. aid not yet begun, it seemed certain that Britain would soon follow the fate of France. However, Winston Churchill, the new British prime minister, promised his nation and the world that Britain would “never surrender,” and the British people mobilized behind their defiant leader.
On June 5, the Luftwaffe began attacks on English Channel ports and convoys, and on June 30 Germany seized control of the undefended Channel Islands. On July 10–the first day of the Battle of Britain according to the RAF–the Luftwaffe intensified its bombing of British ports. Six days later, Hitler ordered the German army and navy to prepare for Operation Sea Lion. On July 19, the German leader made a speech in Berlin in which he offered a conditional peace to the British government: Britain would keep its empire and be spared from invasion if its leaders accepted the German domination of the European continent. A simple radio message from Lord Halifax swept the proposal away.
The costly raid convinced the German high command that the Luftwaffe could not achieve air supremacy over Britain, and the next day daylight attacks were replaced with nighttime sorties as a concession of defeat. On September 19, Nazi leader Adolf Hitler postponed indefinitely “Operation Sea Lion”–the amphibious invasion of Britain. The Battle of Britain, however, continued.
