The United States National Park Service estimates that, when taking into account those who likely perished later of wounds received on this field, the count of those who lost their lives because of this single day of battle could exceed 7,000. No other day in American history produced a greater number of casualties. If the battle lasted about 11 hours, 6am to 5pm, that meant on average one casualty inflicted every 1 1/2 seconds. Of those casualties, one man would die for every 5 to 6 seconds of conflict.
