'Two potential choices here, gentlemen. The first, that Lee is preparing for a general pullout, the first action to be the moving up of his pontoon bridge and getting it in place, followed within hours by the evacuation of Baltimore."

"Do you think he'is pulling out?" Lincoln could not help but ask.

Grant emphatically shook his head. "No, Mr. President. Everything we know of Lee is that he is extraordinarily aggressive. He has won three great battles in a row, starting with Chancellorsville, and he has destroyed the Army of the Potomac. I am confident he will want to face us and seek a single battle of decision. But Lee is not a wild gambler. He is a very smart, calculating risk taker. I believe he is simply taking a safe move at the start. Chances are he has no idea we are even aware of it. In fact, it is fair to assume he has no idea at all. He is just doing what any general does before an action, no matter how aggressive he is, to secure a line of retreat before moving forward to action. Lee will stay and fight. There will be another battle soon, and it will be in Maryland."

Grant paused, hands on the table, looking down at the map again.

"I do not want him to have that line of retreat. We allow him to do that, things go against him, he can then get out and retreat to Virginia to lick his wounds and prepare for yet another campaign. We've got to stop that train from getting any farther than the east side of Monocacy Creek, just outside of Frederick."

Lincoln took all this in with great interest. He sensed that Grant was already thinking beyond a single battle, the events of tomorrow or the day after; he was thinking out an entire campaign, perhaps two battles, half a dozen, but all with the ultimate intent of keeping Lee north of the Potomac and destroying him.

He continued to watch, saying nothing, but feeling an ever deepening reassurance.

Grant stood up and looked around at his staff.

"Ely, send a dispatch to General McPherson. The easy marching is over. His current location?"

"Sir, according to our schedule, by noon the head of his column should be down near Greencastle."

"Fine. I want a fast courier down to him now. Wfite out the orders for me and I'll sign them. General McPherson is to force-march through Hagerstown, then cross over the South Mountains and Catoctin ranges. I expect him in Frederick by late tomorrow, to secure that town and block the west bank of the Monocacy. That will be thirty-five miles of tough marching, and his men had better be ready to fight at the end of it."

"Second order," and as he spoke, Ely had a notebook out, scribbling away furiously. "Get a courier over to Custer, tell him he is authorized to gain the west bank of the Monocacy, secure the rail crossing at Frederick, and burn all the bridges. That will bottle Lee upon the other side."

"Sir, there are three bridges at Monocacy."

Henry Hunt, who had been standing quietly with the staff officers, stepped forward.

Lincoln caught Hunt's eye and nodded an acknowledgment. This was the officer who had brought in the first report to him of the debacle at Union Mills.

"I was there, sir, June 28, reporting to General Meade after he took command of the Army of the Potomac. I remember the railroad bridge as a temporary wooden structure. The iron bridge was blown last year during the Antietam campaign. There's also a solid covered bridge, double wide, two spans, within rifle range of the railroad bridge. Then there's a heavy stone bridge where the National Road crosses the river, a half mile or so north of the rail bridge. I don't think Custer will have the munitions to destroy that one."

"Thank you, Hunt. But at least Custer can make a fight for that."

"If they can push him back, regain the west bank, and have some engineering troops, that railroad span could be brought back up in fairly short order," Hunt continued.

"That's why I want McPherson in there," Grant said, and Hunt nodded in agreement.

"Third order, I want the pace of the corps following McPherson to be picked up. We are not going to leave him out there dangling. Now get to work, gentlemen."

The group scattered, calling for their mounts; Ely remained seated. He tore off a sheet of paper and began to draft orders.

Lincoln Watched, taking it all in. There was no panic, no confusion, no debate. Orders had been given decisively and were now being acted on, all done in a matter of minutes.

Grant looked over at Lincoln and nodded. Sheridan stood to one side, saying nothing.

"Phil, stand by me, for I might need you shortly." "Yes, sir."

A subtle gesture on Lincoln's part indicated that he wished to talk. He and Grant stepped out from under the awning and slowly walked halfway down to the road, where troops were continuing to pass, not yet aware of what was transpiring.

"Did this catch you off guard, General?" Lincoln asked.

Grant shook his head.

"Not seriously. A standard opening move."

"So Lee is not escaping?"

"I can't promise that, sir, but if the shoes were reversed, I know I would not give up all the gains I had achieved without a fight. As I said yesterday, we want his victories to be a trap, to hold him in place. He is just displaying a bit of caution here with the movement of the pontoon train."

"So why block him?"

Grant smiled.

"Two reasons. First off, he'll wonder how we knew. If Custer sweeps down ahead of the trains, burns the bridge, or better yet captures the bridging material, Lee will be caught off balance and it will set him to wondering, something I want him to do. Second, it sets the stage for our meeting. McPherson coming down on Frederick, that's an open challenge for a fight he cannot resist."

"And yet this seems to disrupt your plans?"

"Not seriously. I planned all along to maneuver west of the mountains as far as Frederick, then come down and face him. If time had permitted, perhaps even push far enough eastward to block him entirely from the Potomac and link up with the Washington garrison. I don't think that will happen now. He'll figure out Couch by the end of this day and the diversion I set for him with the militia. Then it is fair to assume he will ascertain the rest, but we will be on the move to block that."

"This Custer left a wide-open hole in that screen," Lincoin asked. "Suppose he is off on a fool's errand, planted by some rebel agent."

"Then General Custer will be Captain Custer doing garrison duty in Kansas or the Dakotas," Grant said coolly.

"But I was not there when this civilian came in, so for the moment I'll have to trust Custer's judgment. He made the decision of a general, and I will back him until proven wrong. If I don't do that, no general under me will have the audacity to take a chance. I only get angry when they've done so on what is obviously information they should have seen through or do not act when the evidence before them is as plain as day but they lack the courage to act.

"Besides, our little farce with Couch could not have lasted much longer. We wanted the rebels to see him at long distance but not get close enough to figure out the truth. That was bound to unravel at some point."

"The Baltimore and Ohio, though."

"Yes, it gives Lee an interesting advantage. Plenty of rolling stock and locomotives in Baltimore. He might use that to move swiftly, while my men will be on foot."

Grant smiled again.

"My men will just have to move hard and fast."

"A curious point, General, from earlier," Lincoln said casually. "You mentioned how a general always keeps a line of retreat open. Yet you risked all back in May when you crossed the Mississippi, then cut a hundred miles into that state with no line of supply or retreat. Isn't that a violation of the rule you just said Lee would follow?"

"That was different, sir. Frankly, I knew the mettle of my opponents, and knew I could do it and win."
