And as far as the attempted yankee invasion of Texas was concerned, Sabine Pass changed the course of the war between the states here.
But still, my point of analogy was that the forces that faced off at Sabine Pass were up against odds as great if not greater than Thermopylae. The numbers compare, especially the final stand of the 300 spartans against an invasion force of several thousand. 44 confederates stood at Sabine Pass against an invasion force of several thousand. See the picture?
Whatever it was I am sure it compares precisely with one of the most significant battles in the history of the world.
An engagement which at its most significant redirected Union forces away from an entirely irrelevent theater of the War surely compares to the most famous in history which if lost by the Spartans could have changed the face of the Western world.
