‘‘I didn’t much know, and I didn’t much care what was going on. The row of that trooper falling ought to have scared half the country, and I would take my oath that we were being stalked by a full regiment in the rear, and they were making row enough to rouse all Afghanistan. I sat tight, but nothing happened.’
This is from 'Lost Region' by Rudyard Kipling. http://www.telelib.com/authors/K/KiplingRudyard/prose/ManyInventions/lostlegion.html
I don't understand the meaning of "scared half the country"
I am glad if someone would kindly teach me.
