Generals Grant and Buell were at the time marching towards Corinth, Mississippi, where a junction was to be made. The Confederate troops were concentrating at the same point, and there was immediate trouble brewing. General Mitchell, who was in command of one of Buell's divisions, had advanced as far as Huntsville, Alabama, and another detachment had got within thirty miles of Chattanooga. It was deemed advisable, and even necessary, to cut off the railway communication between Chattanooga and the East and South, and James J. Andrews was selected by General Buell for the task.

Andrews picked out twenty-four spirits like unto himself, who entered the enemy's territory in ordinary Southern dress, and without any other arms than revolvers.

Their purpose was to capture a train, burn the bridges on the northern part of the Georgia State Railroad, and also on the East Tennessee Railroad, where it approaches the Georgia State line, thus completely isolating Chattanooga, which was then virtually ungarrisoned. These men rendezvoused at Marietta, Georgia, more than 200 miles from the point of departure, having (with the exception of five, who were captured en route or belated) made their way thither in small detachments of three and four. The railroad at Marietta was found to be crowded with trains, and many soldiers were among the passengers.

After much reconnoitering, it was determined to capture a train at Big Shanty, a few miles north of Marietta, and, purchasing tickets for different stations along the line in the direction of Chattanooga, the party, which included two engineers, reached Big Shanty.

While the conductor, the engineer, and most of the passengers were at breakfast, the train was seized, and being properly manned, after the uncoupling of the passenger cars, was started on its fierce race northward. Think of the exploit--twenty men, with a hostile army about them, setting out thus bravely on a long and difficult road crowded with enemies.

Of course the theft of the train 'produced great consternation, but the captors got away in safety, stopping frequently for the purpose of tearing up the track, cutting telegraph wires, etc. Andrews informed the people at the stations that he was an agent of General Beauregard, running an impressed powder train through to Corinth, and generally this silenced their doubts, though some acted suspiciously.

The first serious obstacle was met at Kingston, thirty miles on the journey. Here the captors and their train were obliged to wait until three trains south-bound passed by. For an hour and five minutes they remained in this most critical position, sixteen men being shut up in the box-car, personating Beauregard's ammunition. Just as the train got away from Kingston two pursuers appeared, being Captain W. A. Fuller, the conductor of the stolen train, and an officer who happened to be aboard of it at the time it was run out from Big Shanty. Finding a hand-car, they had manned it and pushed forward until they had found an old locomotive standing with steam up on a side track, which they immediately loaded with soldiers and hurried forward with flying wheels in pursuit, until Kingston was reached, where they took the engine and a car of one of the waiting trains, and with forty armed Confederates continued the journey.

It was now nip and tuck, with one engine rushing wildly after another. To wreck the pursuing train was the only tangible hope of the fugitives, who stopped again and again in order to loosen a rail. Had they been equipped with proper tools they could have done this easily, but as it was, they simply lost precious time. Once they were almost overtaken by the pursuing engine, and compelled to set out again at a terrible speed. At one point at Adairsville, they narrowly escaped running into an express train. Fuller, the conductor of the stolen train, and his companions, being arrested by the obstructions of the track, left their engine behind and started on foot, finally taking possession of the express passed at Adairsville, and turning it back in pursuit.

When Calhoun was passed, the trains were within sight of each other. The track was believed to be clear to Chattanooga, and if only the pursuing train could be wrecked, the end would be gained. Again the lack of tools hampered the daring little band. They made desperate effort to break a rail, but the pursuers were upon them before they had accomplished it, and Andrews hurried on his engine, dropping one car and then another, which were picked up and pushed ahead, by the pursuers, to Resaca Station.

Both engines were, at the time, at the highest rate of speed. Andrews at last broke off the end of his last box car and dropped crossties on the track as he ran. Several times he almost lifted a rail, but each time the coming of the Confederates within rifle range compelled him to desist.
