Come, stack arms, Men! Pile on the rails; stir up the campfire bright; no matter if the canteen fails, we'll make a roaring night. Here Shenandoah brawls along, there burly Blue Ridge echoes strong, to swell the Brigade's rousing song, of “Stonewall Jackson’s Way.”

We see him now — the old slouched hat cocked o’er his eye askew, the shrewd, dry smile, the speech so pat, so calm, so blunt, so true. The “Blue-Light Elder” knows ’em well; says he, “That’s Banks — he’s fond of shell; Lord save his soul! We’ll give him” — well, that’s “Stonewall Jackson’s Way.”

Silence! Ground arms! Kneel all! Caps off! Old Blue Light’s going to pray. Strangle the fool that dares to scoff: Attention! 'Tis his way. Appealing from his native sod in forma pauperis to God: “Lay bare thine arm, stretch forth thy rod! Amen!” That’s “Stonewall’s Way.”

He’s in the saddle now. Fall in! Steady, the whole brigade! Hill’s at the ford, cut off — we’ll win his way out, ball and blade! What matter if our shoes are worn? What matter if our feet are torn? “Quick step! We’re with him before the morn!” That’s “Stonewall Jackson’s Way.”

The sun’s bright lances rout the mists of morning, and by George! Here’s Longstreet struggling in the lists, hemmed in an ugly gorge. Pope and his Yankees, whipped before, “Bay’nets and grape!” hear Stonewall roar; “Charge, Stuart! Pay off Ashby’s score!” in “Stonewall Jackson’s Way.”

Wife, sew on, pray on, hope on! Thy life shall not be all forlorn. The foe had better ne’er been born that gets in “Stonewall’s Way.”
