It was an immense task; and it needs to be remembered by each succeeding generation. For, as Obama also told his audience, "As we face down the hardships and struggles of our time, and arrive at that hour for which we were born, we cannot help but draw strength from those moments in history when the best among us were somehow able to swallow their fears and secure a beachhead on an unforgiving shore."
It is also important to remember that "the best among us" were ordinary people -- from all over the world, from city and farm, from a plethora of backgrounds -- who worked together for a good that was more important than their own self interest.
Most of the soldiers who landed that day -- including those who did not come home -- achieved no notoriety. They have been lost to the culture of celebrity. And, as their dwindling numbers attest, there is a danger that what they did will be forgotten with their passing. We must not let that happen. For their sake and for our own.
