Yes, sorry, I was referring to the fact they were sharpshooting but that could cause confusion. Thanks for highlighting that.Not sharpshooters, regular infantrymen. These figures are determined by hits achieved/ ammunition expended for all the infantry. Now, many of them were firing as dispersed skirmishers at long ranges, but these were not picked sharpshooters.
I believe it's the case that we have good numbers for the number of Minie ball wounded at Inkerman (1 for every 22 Minie balls fired) exclusive of those killed.
The high hit rate also explains a lot about the nature of the action, because very heavy Russian attacks were repulsed principally by rifle fire.
