Excerpted from Ronald Reagan’s speech on the 40th anniversary of D-Day–June 6, 1984

Read the speech in its entirety here. 

We stand on a lonely, windswept point on the northern shore of France. The air is soft, but 40 years ago at this moment, the air was dense with smoke and the cries of men, and the air was filled with the crack of rifle fire and the roar of cannon. At dawn, on the morning of the 6th of June, 1944, 225 Rangers jumped off the British landing craft and ran to the bottom of these cliffs. Their mission was one of the most difficult and daring of the invasion: to climb these sheer and desolate cliffs and take out the enemy guns.

Forty summers have passed since the battle that you fought here. You were young the day you took these cliffs; some of you were hardly more than boys, with the deepest joys of life before you. Yet, you risked everything here. Why? Why did you do it? What impelled you to put aside the instinct for self-preservation and risk your lives to take these cliffs? What inspired all the men of the armies that met here? We look at you, and somehow we know the answer. It was faith and belief; it was loyalty and love.

The men of Normandy had faith that what they were doing was right, faith that they fought for all humanity, faith that a just God would grant them mercy on this beachhead or on the next. It was the deep knowledge — and pray God we have not lost it — that there is a profound, moral difference between the use of force for liberation and the use of force for conquest. You were here to liberate, not to conquer, and so you and those others did not doubt your cause. And you were right not to doubt.

You all knew that some things are worth dying for. One’s country is worth dying for, and democracy is worth dying for, because it’s the most deeply honorable form of government ever devised by man. All of you loved liberty. All of you were willing to fight tyranny, and you knew the people of your countries were behind you.

The Americans who fought here that morning knew word of the invasion was spreading through the darkness back home. They fought — or felt in their hearts, though they couldn’t know in fact, that in Georgia they were filling the churches at 4 a.m., in Kansas they were kneeling on their porches and praying, and in Philadelphia they were ringing the Liberty Bell.

We are bound today by what bound us 40 years ago, the same loyalties, traditions, and beliefs. We’re bound by reality. The strength of America’s allies is vital to the United States, and the American security guarantee is essential to the continued freedom of Europe’s democracies. We were with you then; we are with you now. Your hopes are our hopes, and your destiny is our destiny.

Here, in this place where the West held together, let us make a vow to our dead. Let us show them by our actions that we understand what they died for.

Strengthened by their courage, heartened by their value [valor], and borne by their memory, let us continue to stand for the ideals for which they lived and died.
