In the poem "Barbara Frietchie,” which is the direct result of an action taken by Stonewall Jackson?
He glanced: the old flag met his sight.
When Lee marched over the mountain wall,—
It shivered the window, pane and sash;
Flapped in the morning wind: the sun

In "Barbara Frietchie" the action taken by Stonewall Jackson is given below.

Explanation:

John Greenleaf Whittier, a popular American poet, New Englander and 19th-century abolitionist, wrote "Barbara Frietchie" in 1863.

According to the poem, the 95-year-old Fritchie had an American flag flying outside her home as Confederate soldiers marched by, on their way west, in September 1862. The soldiers were preparing for battle, which would come a few days later at South Mountain and Antietam. Legend has it the soldiers ripped down the flag, snapping the staff. She took the flag and hung it out her second-story window.

Confederate Gen. Stonewall Jackson ordered his troops to fire upon the flag.

"Quick, as it fell, from the broken staff

Dame Barbara snatched the silken scarf.

She leaned far out the window-sill,

And shook it forth with a royal will.

'Shoot, if you must, this old gray head,

But spare your country's flag,' she said.

A shade of sadness, a blush of shame,

Over the face of the leader came";

According to the legend, Jackson ordered his troops to move on, leaving Fritchie's flag intact.
