June 2020. In 2020, the Royal British Legion is asking the nation to remember the impact that leaving, missing and, returning home has on service men and women and their loved ones – then and now. The anniversary of D-Day brings this message to life as we remember one of the most important battles of the 20th century, a battle that paved the way for the liberation of Western Europe. They remember the British, Commonwealth and, Allied forces who from land, sea or air contributed to the success of the largest amphibious operation in history.
