"To sink the foe or save the maimed, Our mission and our pride, We'll carry on 'til Kingdom Come, Ideals for which we've died." Thus went the anthem of the U.S. Coast Guard, which was established this day, Aug. 4, 1790, when Congress authorized ten boats to be built for the Revenue Marine. Four years later they were charged with stopping slave traders from bringing new slaves from Africa. They freed almost 500 slaves. At a U.S. Coast Guard commencement, President Reagan stated: "It's our prayer to serve America in peace. It's our commitment to defend her in war."
