The chief quartermaster of the corps and the chief of artillery had each his appropriate flag, as designated in the color-plate, but the arrangement of the colors in the flag of the chief quartermasters differed in different corps.

This scheme of Hooker’s, for distinguishing corps, division, and brigade headquarters remained unchanged till the end of the war.

The brigades took turns in having the lead—or, as military men say, the right—of the division, and regiments had the right of brigades by turns.

There goes army headquarters yonder—the commanding general, with his numerous staff—making for the head of the column. His flag is the simple star-spangled banner. The stars and stripes were a common flag for army headquarters. It was General Meade’s headquarters flag till Grant came to the Army of the Potomac, who also used it for that purpose. This made it necessary for Meade to change, which he did, finally adopting a lilac-colored swallow-tail flag, about the size of the corps headquarters flags, having in the field a wreath enclosing an eagle, in gold.

You can easily count the regiments in column by their United States colors. A few of them, you will notice, have a battle-flag, bearing the names of the engagements in which they have participated. Some regiments used the national colors for a battle-flag, some the state colors. I think the volunteers did not adopt the idea early in the war. Originally battles were only inscribed on flags by authority of the secretary of war, that is, in the regular army. But the volunteers seemed to be a law unto themselves, and, while many flags in existence to-day bear names of battles inscribed by order of the commanding general, there are some with inscriptions of battles which the troops were hardly in hearing of. The Rebel battle-flag was a blue spangled saltier in a red field, and originated with General Joe Johnston after the first Bull Run.

You will have little difficulty in deciding where a regiment begins or ends. It begins with a field officer and ends with a mule. Originally it ended with several army wagons; but now that portion of regimental headquarters baggage which has not gone to the wagon-train is to be found stowed about the mule, that is led along by a contraband. Yes, the head, ears, and feet which you see are the only visible externals of a mule. He is “clothed upon” with the various materials necessary to prepare a “square meal” for the colonel and other headquarters officers. His trappings would, seemingly, fit out a small family in household goods of a kind. There is a mess-kettle, a fry-pan, mess-pans, tent-poles, a fly (canvas), a valise, a knapsack and haversack, a hamper on each side, a musket, and other matter which goes to make the burden at least twice the size of the animal. Four mules were regarded as having the carrying capacity of one army wagon. At the end of the brigade you will see two or three of these mules burdened with the belongings of brigade headquarters.

The mule had other company than the negro ofttimes. That man who seems to be flour and grease from head to heels, who needs no shelter nor rubber blanket because he is waterproof already, perhaps, inside and out, whose shabby, well-stuffed knapsack furnishes the complement to the mule’s lading, who shuffles along with “no style about him,” is the cook, perhaps, for the regiment, probably for headquarters, certainly not for Delmonico. It is singular, but none the less true, that if a man made a slovenly, indifferent soldier he was fully as likely to get a berth in the cook-house as to have any other fate befall him. This remark applies to men who drifted into the business of “army caterer” after trying other service, and not those who entered at once upon it.

Here comes a light battery at the rear of the division. Possibly it is to remain with this part of the corps for the campaign. Such was sometimes the case, but later a battery was often used anywhere within the limits of a corps that it could be of advantage. This battery has six brass Napoleons, 12-pounders. They are very destructive at short range. It is followed by a battery of steel guns. They are Parrots, three-inch rifles; best for long range, but good anywhere. Not so safe for close action, however, as the Napoleons.

Yonder you can see the Second Division moving across the fields, made up like the one just passed. It will close in upon the rear of this division farther up the road. What an interesting spectacle it presents, the bright sunlight glinting from the thousands of polished muskets, the moving masses of light and dark blue inching along over the uneven ground, the various flags streaming proudly in the air, marking off the separate brigades and regiments. The column is moving at a moderate pace. It takes some time for a corps to get under way. If we wait long enough, the Third Division, made up like the others, will pass by us, unless it has gone on a parallel road.

It is growing warmer. The column has now got straightened out, and for the last hour has moved forward quite rapidly. The road is evidently clear of all obstructions, but the heat and speed begin to tell on the men. Look at the ground which that brigade has just vacated after its brief halt for rest. It is strewn with blankets, overcoats, dress-coats, pantaloons, shirts—in fact, a little of everything from the outfit of the common soldier. As the Second Corps advanced into the Wilderness on the morning of May 4, 1864, I saw an area of an acre or more almost literally covered with the articles above named, many of them probably extras, but some of them the sole garment of their kind, left by the owners, who felt compelled, from the increasing weight of their load, to lighten it to the extent of parting with the blankets which they would need that very night for shelter. This lightening of the load began before the columns had been on the road an hour. A soldier who had been through the mill would not wait for a general halt to occur before parting with a portion of his load, if it oppressed him; but a recruit would hang to his until he bent over at an angle of 45° from a vertical, with his eyes staring, his lower jaw hanging, and his face dripping with moisture. If you were to follow the column after, say, the first two miles, you would find various articles scattered along at intervals by the roadside, where a soldier quietly stepped out of the ranks, sat down, unslung his knapsack or his blanket-roll, took out what he had decided to throw away, again equipped himself, and, thus relieved, hastened on to overtake the regiment. It did not take an army long to get into light marching order after it was once fairly on the road.
