In The US infantry tactics from 1861. (Hardee's 1855 book with a new front page and both the manual arms for muskets and rifles) there is at the end an interesting "Lesson"
It describe the orders and procedure for how to do "Street Firing."
I got no evidence that is was actually used during the civil war... But with this game having a map with combat in Harper's Ferry it might be relevant to use there.
(obviusly Fredricksburg or the 1st day at Gettysburg are two times where it might have been used.)
LESSON VIII.
STREET FIRING
717. Street firing is the method of firing adapted to defend or clear a street, lane, or narrow pass, in the execution of which the company or platoon must be formed according to the width of the place, leaving sufficient space on the flanks for the platoons to file successively to the rear.
718. When the column has arrived at the place where the firing is to commence, the commanding officer will give the command:
1. Column - HALT. 2. Prepare for Street Firing.
719. At this command, all the captains will pass by the right flank to the rear of their companies, covering the centre. The colonel next commands:
Commence - FIRING.
720. The captain of the first company will promptly command:
1. First company. 2. Ready. 3. Aim. 4. FIRE.
5. Recover - ARMS. 6. Outward - FACE. 7. MARCH.
721. The first platoon faces to the right, the second to the left; the first platoon conducted by the captain, the second by the first lieutenant, will file right and left around the flanks towards the rear, halt on the flanks opposite the centre of the column, re-load, and as soon as the rear of the column has passed the platoons, the captain will command:
1. Platoons. 2. Right and Left Face. 3. MARCH.
722. At which command, the first platoon faces to the left, and files left; and the second to the right, and files right; and unite in rear of the column. At the instant the soldiers of the first company recover their arms after firing, the captain of the second will order:
1. Second Company. 2. Ready.
723. The second company will wait in that position until the front is cleared by the first company, when the captain will cause it to advance twice its front (followed by all the companies in the rear), and fire, file down the ranks in the same order as prescribed for the first company.
724. Firing in retreat is conducted on the same principles as on the advance, except that the companies fire without advancing, on the front being cleared by the former company; and, instead of halting on the flanks, the platoons will pass immediately to the rear of the column, counter-march, form, and re-load. The same principles will be observed in column of platoons as column of company.

At the end it got an interesting commend about how one can use use "the mounted howitzer" to help limited damage to property.... when suppressing riots and insurrections.
The text, originally written by the french army, is clearly made with riots in Paris in mind.
(The population of Paris revolted in 1787, 1830, 1848 and 1871... and likely in other cases as well. So it makes sense that the french army wanted a procedure for it... and one that the officers and men should know.)
