That was getting late in the period of muskets (especially the Anglo-Afghan Wars), and guerrilla tactics can do damage, but a decisive defeat usually requires a field battle (where the Americans used linear tactics like the British).
Skirmishers had roles in European Armies (both musket and later rifle armed).
For the British in Afghanistan most of the battles were clear British victories. The only major Afghan victory was the massacre of the British army that thought it was in a safe withdrawal. Primarily through ambushes and continuous harassment. The Afghans had every advantage in the books.
The only other significant Afghan victory I can think of, they had a numerical advantage of 10:1 and suffered far heavier casualties.
There were disadvantages to linear tactics, but overall the advantages far outweighed them. Even with the adoption of the Minie rifle, linear tactics still had large benefits, in particular to stop charges and defense against infantry.
