That from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth. -  President Abraham Lincoln

On the battlefield, the military pledges to leave no soldier behind. As a Nation, let it be our pledge that when they return home, we leave no veteran behind.
