Meanwhile Gen. Lee’s army was rushing down the roads from Culpeper and Orange counties to occupy the crest of hills around Fredericksburg. Wednesday, at daybreak, General Fitzhugh Lee’s cavalry arrived. The next morning General McLaws, with his own division and that of General Ransom’s, was in position, and on the 20th the Commander-in-Chief was at hand to direct the movements of the remainder of General Longstreet’s command and General Jackson’s corps, which rapidly followed him.

On Tuesday, the 20th of November, by request of General Lee, Montgomery Slaughter, Mayor of Fredericksburg, accompanied by the Recorder, William A. Little, Esq., and by Mr. Douglas H. Gordon, a member of her Council, held an interview with the Confederate Commander-in-Chief. It was held at Snowden, the residence of the late John L. Stansbury, about a mile above town. On Friday, the 21st, General E. V. Sumner, of the Federal Army, sent over a flag of trace, with a written message to the Mayor and Common Council of Fredericksburg. General Patrick, the bearer of the message, was met by Colonel Wm. A. Ball at “French John’s” wharf, at the foot of Hawke street. General Sumner’s letter, to the town authorities was as follows:

“Gentlemen:—Under cover of the houses of your town, shots have been fired upon the troops of my command. Your mills and factories are furnishing provisions and material for clothing for armed bodies in rebellion against the Government of the United States. Your railroads and other means of transportation are removing supplies to the depots of such troops. This condition of things must terminate; and by direction of Major-General Burnside, commanding this army, I accordingly demand the surrender of the city into my hands, as the representative of the Government of the United States, at or before five o’clock this afternoon (5 o’clock P. M. to-day). Failing an affirmative reply to this demand by the time indicated, sixteen (16 hours) hours will be permitted to elapse for the removal from the city of women and children, the sick, wounded and aged; which period having elapsed, I shall proceed to shell the town.

“Upon obtaining possession of the town every necessary means will be taken to preserve order and secure the protective operation of the laws and policy of the United States Government.”

Colonel Ball simply stated to General Patrick that before delivering the letter to the civil authorities it must be referred to his commanding military officer. But neither he nor the Mayor gave any intimation of the actual presence of General Lee, with a large part of his army, on the heights in rear of the town. General Patrick was obliged to remain in the log house from ten o’clock in the morning to seven in the afternoon, on the 21st. Meanwhile Colonel Ball, through the proper channels forwarded the letter to General Lee. At twenty minutes before five o’clock in the afternoon the letter was received at his office by the Mayor, through General J. E. B. Stuart, who communicated in full General Lee’s decision. With the aid of his advisers, Mayor Slaughter prepared a written reply, bearing date, “Mayor’s Office, Fredericksburg, November 21st, 1862.” This reply was to the effect that the communication of General Sumner had not reached the Mayor in time to furnish a reply by 5 o’clock P. M., as requested; that it had been sent to him after passing (by General Patrick’s consent) through the hands of the commanding officer of the Confederate States forces near the town; that as to the shots complained of in the northern suburbs of the town, they were the acts of the Confederate military force holding the town; that the Mayor was authorized to say that the several subjects of complaint would not recur; that the Confederate troops would not occupy the town, and neither would they permit the Federal troops to do so. Mayor Slaughter, attended by Dr. Wm. S. Scott and Samuel S. Howison, Esq., repaired to the place of meeting, and, at about seven o’clock in the evening, delivered the reply to General Patrick.

In view of the threatened shelling of the town, General Lee advised the inhabitants to remove from it as rapidly as possible. The bombardment was not opened the next morning, but it became apparent that the enemy would cross, and the town would be exposed, not only to their fire, but to the most terrible desolations of war. The humane and considerate Chief of the Confederate army urged the women and children to leave the town, and furnished wagons, ambulances and every facility in his power for their aid.

THE INHABITANTS LEAVE THEIR HOMES.

Then followed a scene, illustrating both the horrors of war and the virtues to which it sometimes gives birth. The people of Fredericksburg, almost en masse, left their homes rather than yield to the enemy. Trains of cars departed, full of refugees. Upon the last the enemy opened a fire of shells; they afterwards explained that it was a mistake. Wagons and vehicles of every kind left the town filled with women and little children, with the few articles of apparel and necessity that could be removed. Many were seen on foot along the roads leading into the country. Winter had commenced, and snow had fallen. Many were compelled to take refuge in cabins, barns and tents, scattered through the woods and fields. They were dependent for food on the exertions of their friends and the humane efforts of the Southern army.

A few families remained in Fredericksburg, determined to brave the horrors of war as long as possible. The hardships and privations, incurred by these people, who surrendered their homes and property to destruction rather than remain with them and fall into the hands of the enemies of their country, excited the sympathy and won the admiration of the South. A movement to aid them commenced in Richmond. A committee of relief and treasurer was appointed, and funds were liberally contributed throughout the South, and the soldiers in the field, of their small rations and pay, contributed generously, both in food and money. The contributions of the people and army continued until more than ninety thousand dollars had been received and disbursed by the committee in Richmond and nearly an equal, if not greater, sum was distributed by Mayor Slaughter.

A number of skirmishes of an unimportant character were soon followed by the grand movement of the enemy. On the night of December the 10th the armies prepared for action. Two hundred and fifty thousand armed men, like crouched lions ready to spring upon their adversary, were ready for the bloody conflict. It was the most restless, anxious night ever passed by the citizens of Fredericksburg. It was the night of terror! The dread of to-morrow hung like a pall over the devoted city, and everybody was hurriedly preparing for the awful destruction that was at hand and could not be averted. The threatened bombardment had long been delayed, and many citizens had returned from their flight. From one end of the town to the other, all during that sleepless night, could be seen in nearly every home dim lights, where busy hands with heavy hearts were preparing for the flight at the sound of the first gun. What to attempt to carry, and what to leave to be destroyed by the enemy, was the perplexing question, and so in the anxiety of the refugees to take with them sufficient food, clothing and bedding to prevent suffering from cold and hunger, they overtaxed their strength and had to abandon many things on the roadside.
