It was just daylight when the line of Union Infantry took their positions on the north side of the pasture in middle Tennessee near Nashville. Behind the infantry, the artillery batteries had wheeled their cannons into place and were in the process of loading their guns.
The Union General could see that the Confederate troops on the other side of the pasture were doing the same thing. The Confederate line stretched across the open field for almost a quarter of a mile, a quarter of a mile of soldiers in gray with their rifles at the ready, and behind them, six cannons all pointed at his infantry.
He knew the cannons would fire first, the iron cannon balls with delayed fuses hurtling toward his troops. Some would make it to the ranks of blue before exploding and then killing or severely wounding any soldier within a hundred feet. The cannon balls that didn't make it that far, and some would be aimed with that intention, would skip over the soil of the pasture and then plow through the massed troops before exploding.
Men would be laid low, either dead or dismembered by the six and twelve pound balls of death before they hit the ranks of the artillery and exploded. His own artillery was taking aim to cause the exact same effect.
It had all been planned in conferences before the battle, planned down to the last detail of which cannons on either side would fire first, which would be destroyed, how many men would fall when each volley of rifle shots was fired, and how fast the opposing armies would close on each other.
The planning conferences were required because the cost of filming the battle prohibited more than one filming session. There were around three hundred extras on each side of the pasture, three hundred men in authentic uniforms and carrying reproductions of Civil War Era firearms. CGI would expand that three hundred to a thousand on each side in order to save cost.
Most of the rifles were just prop guns, but two Civil War reenactment groups were also participating and would be the extras used for the close up shots. They were armed with fully functioning rifles and paper cartridges filled with black powder.
The cannons behind the troops were mostly fiberglass mockups of the real thing, but there were several functional cannons on each side of the battlefield. Those cannons would be loaded with black powder charges wrapped in aluminum foil and designed to produce the same level of sound and smoke as similar pastures and fields had witnessed in 1864. The cannon balls would be added later by the CGI artists. Those cannons were owned and manned by men from Civil War reenactment groups.
When the cameras were all in place, the director gave the command over the PA system for the cameramen to begin filming. Ten seconds later, the reenactors fired the first of the cannons on the Union side of the field. A few seconds later, the reenactors on the Confederate side likewise touched off the cannons for which they were responsible.
For five minutes, the pasture was clouded in white smoke as cannons kept firing and the cameras recorded the simulated landing of cannon balls among the troops. The stunt men wearing the appropriate uniforms either fell when the small charge beside them blew soil and grass into the air, or staggered away holding an arm or crawled away. CGI would take away part of an arm or leg during postproduction.
Close-up shots of men with those injuries would also be added during postproduction. Those injuries would be constructed by the makeup artists employed by the production company and would show the horrible amputations complete with mangled flesh, ragged bone ends and spurting blood. The screams of men in agony would be added later by the Foley artists in a sound studio.
When the director spoke on the PA system again, it was to start the infantry action. Both sides then erupted in gunfire that filled the space between them with more white smoke. After the first volley, both sides began to close the distance between them, the second rank moving up past the first and firing, then staying in place as the third rank moved up to pass them. This leapfrogging maneuver closed the gap by about ten feet once every minute or so.
The Union advance would continue until the Confederate general gave the order to retreat. The men in gray would turn around and run away from the pasture leaving their dead and wounded where they fell. The two lines were about fifty yards apart when the director gave that order.
When all the men in gray uniforms had run back to the trees that bordered the pasture, the director picked up his microphone.
"OK everybody, that's a wrap. I think we got everything we need so turn your weapons in to the armorer and your uniforms to property."
At that statement, both sides began walking back to the cluster of trailers and tents that housed the production company. The supposedly dead and wounded lying on the battlefield stood up went with them.
The director was speaking with one of the cameramen when there was a shout from the center of the pasture. He looked up and saw one of the extras standing beside a man on the ground and waving his arms.
The local EMT's who were there in case one of the actors was injured or fell victim to heat stroke on the hot day had also heard the shout and saw the man waving his arms, and they were in their truck and driving toward the two men. The director, thinking the man had just fallen wrong, turned back to finish his conversation with the cameraman.
That conversation lasted for about another minute before the EMT truck came racing back across the field with the lights flashing and the siren screaming. He turned to one of his assistants and told him to find out what had happened. The assistant began walking toward the man who had sounded the alarm.
He came back to the director with that same man, pointed to the director, and said, "Jimmy, tell Mr. Arnold what you told me".
Chuck Arnold, the director of the battle scene, looked up at the man and smiled. He figured it was just a routine set injury. Those things always happened when there were extras involved. Most extras would do what they'd been instructed to do, but a few, thrilled to be in a real movie, would try to enhance their small role. In the process, they'd fall too hard or roll around in faked pain. Most set injuries were simple things -- a sprained ankle or a bruise or cut caused by a stick or rock on the ground. That's why the EMT's were there. The reward for the would-be actor was that part of the scene would be cut during editing.
Chuck was a little concerned because of the lights and siren, so he told the cameraman he'd catch up with him later and then turned back to the man.
"Jimmy is it? OK, Jimmy, what happened?"
Jimmy, obviously shaken, began talking fast.
"Carl and me are in the reenactor group in Franklin and we do this all the time. When everything was over, I seen that Carl wasn't gittin' up. I went over to see what was wrong and there he was bleedin' from a hole in his chest. I think he got shot cause the hole looked like the hole in every deer I've ever shot. He wasn't breathin' very good either. When the EMT's got there, one of them started doing CPR on Carl and the other put a needle in his arm and connected it to a plastic sack of something. I heard one of them say he didn't think Carl was going to make it."
