Where did Britain attempt to open up a second front?

Britain attempted to open up a second front in Europe during World War II by launching the invasion of Normandy, known as D-Day, on June 6, 1944. This operation aimed to relieve pressure on the Soviet Union by forcing Nazi Germany to divert resources and troops to the Western Front. Prior to D-Day, Britain also engaged in various campaigns, such as the Italian Campaign, to establish a presence in Southern Europe.
