GENERAL ORDERS,
No. 17.

HDQRS. DEP’T N. E. VIRGINIA,
Arlington, July 16, 1861.

The troops will march to the front this afternoon in the following order:

1. The brigades of the First Division (Tyler’s) will leave their camps in light marching order, and go as far as Vienna, the Fourth Brigade (Richardson’s) taking the road across the Chain Bridge, and by way of Langley’s, Louisville, and Old Court-House; the others by the Georgetown turnpike and Leesburg Stone roads. The order of march of the several brigades to be arranged by the division commander.

2. The Second Division (Hunter’s) will leave their camps in light marching order, and go on the Columbia turnpike as far as the Little River turnpike, but not to cross it, the Second Brigade (Burnside’s) leading.

3. The Third Division (Heintzelman’s) will leave their camps in light marching order, and go on the old Fairfax Court-House road, south of the Orange and Alexandria Railroad, as far as the Accotink, or the Pohick, if he finds it convenient; the brigades to march in the order the division commander may direct.

4. The Fifth Division (Miles’) will proceed in light marching order, by the Little River turnpike as far as Annandale, or to the point where the road leads to the left to go into the old Braddock road (so called), which runs between the Little River turnpike and the Orange and Alexandria Railroad.

5. The brigades of the several divisions will be put in march in time to reach their respective destinations by dark.

6. The reserve will be held in readiness to march at the shortest notice, and will, on and after the 17th instant, keep constantly a supply of cooked rations on hand for two days.

7. Brigadier-General Runyon, commanding the reserve, will have command of all the troops not on the march to the front, including those in the fortifications and camps. He will, to-morrow, send two regiments up the Orange and Alexandria Railroad to aid the railroad managers in rebuilding it in the shortest possible time, the commanding officers to conform to the plans of the principal managers.

8. Brigadier-General Runyon will guard the Loudoun and Hampshire Railroad as far as the present camps of the Ohio Volunteers, and the Orange and Alexandria Railroad as far as it is or may be repaired.

9. The regiment now in Fort Corcoran, the Twenty-eighth New York; the Twenty-fifth New York, at Roach’s; the Twenty-first New York, at Fort Runyon, and the Seventeenth New York, at Fort Ellsworth, will not be removed from their present stations except in an emergency.

II. On the morning of the 17th the troops will resume their march after daylight in time to reach Fairfax Court-House (the Third Division, Sangster’s) by 8 o’clock a. m.

1. Brigadier-General Tyler will direct his march so as to intercept the enemy’s communication between Fairfax Court-House and Centreville, moving to the right or the left of Germantown, as he may find most practicable. On reaching the Centreville turnpike he will direct the march of his leading brigade either upon Centreville or Fairfax Court-House, as the indication of the enemy may require. The Second Brigade will move on the road in the direction not taken by the First. The rear brigades will be disposed of by the division commander as circumstances may require. Should he deem it best, a brigade may be sent on Fairfax Court-House direct from Flint Hill.

2. The Second Division (Hunter’s) will (after the road shall be cleared of the Fifth Division) move on the direct road to Fairfax Court-House by the Little River turnpike.

3. The Fifth Division (Miles’) will turn off from the Little River turnpike and gain the old Braddock road, which it will follow to its intersection with the road from Fairfax Court-House to Fairfax Station, where it will turn to the right and move on the Court-House.

4. The Third Division (Heintzelman’s) will move by the best and shortest of the roads to the south of the railroad till he reaches the railroad at Sangster’s. He will, according to the indications he may find, turn his Second and Third Brigades to the right, to go to Fairfax Station or to the front to support the First Brigade. He may find it necessary to guard the road coming up from Wolf Run Shoals and the one leading to Yates’ Ford.

III. The enemy is represented to be in force at Centreville, Germantown, Fairfax Court-House, and Fairfax Station, and at intermediate places, and on the road towards Wolf Run Shoals. He has been obstructing, as far as possible, the roads leading to Fairfax Court-House, and is believed on several of these to have thrown up breastworks and planted cannon. It is therefore probable the movements above ordered may lead to an engagement, and everything must be done with a view to this result.

The three following things will not be pardonable in any commander: 1st. To come upon a battery or breastwork without a knowledge of its position. 2d. To be surprised. 3d. To fall back. Advance guards, with vedettes well in front and flankers and vigilance, will guard against the first and second.

The columns are so strong and well provided that, though they may be for a time checked, they should not be overthrown. Each is provided with intrenching tools and axes, and if the country affords facilities for obstructing our march, it also gives equal facilities for sustaining ourselves in any position we obtain. A brigade should sustain itself as long as possible before asking for help from another. It can hardly be necessary to attack a battery in front; in most cases it may be turned. Commanders are enjoined to so conduct their march as to keep their men well closed up. This is of great importance. No man will be allowed to get into an ambulance or baggage wagon without written authority from the regimental surgeon or his superior. Guards will be placed over the ambulances and wagons to enforce this order.

Troops will march without their tents, and wagons will only be taken with them for ammunition, the medical department, and for intrenching tools. A small baggage train for each brigade, to take the camp-kettles, mess-pans, and mess kits, and the smallest allowance of personal baggage of the officers and men, will follow the divisions the day after they march. This train will consist of from twelve to fifteen wagons.

A subsistence train will follow at a day’s interval the First Division from Fort Corcoran and Vienna. A second subsistence train will follow the Second Division at a day’s interval. A wagon for forage will be taken with each battery and squadron. A herd of beef cattle will be sent with each subsistence train. There is on many of our regiments nothing to distinguish them from those of the enemy, and great care must be taken to avoid firing into each other.

The national color must be kept continually displayed, and, if possible, small national colors should be placed on the cannon of the batteries.

Division commanders will see that the axmen and engineers at the head of the columns (and men of the ordnance guard) are well provided and in condition to work efficiently. When there are no ax-slings, the axes will be carried and the muskets will be slung.

Department headquarters will be with the Second Division, on the Little River turnpike. Division commanders will communicate with them by every opportunity.

By command of Brigadier-General McDowell:

JAMES B. FRY, A. A. G.
