I think that you are underestimating the significance of the Flag flying above that brick pile. The eyes of the nation were on that flag and both Lincoln and Davis felt the pressure. When northerners saw the physical condition of that very flag, after it was lowered by Major Anderson, when he was forced to surrender that brick pile to the “Confederacy”, they united behind Lincoln. And then four years later, Anderson raised that flag back above Fort Sumter.
One dead for each brick.
