On June 6, 1944 (D-Day), the Allies invaded France, opening a long-awaited second front. Operation "Overlord" was the largest sea-to-land invasion in history, and perhaps the most logistically complex operation of WW2.  It was also an example of the successful military cooperation among the Allies: to prevent the transfer of German forces  from the Eastern to the Western front, the Russians simultaneously launched a major  offensive in Belarus (Operation “Bagration”).
