Why would they have used engineering bricks to build a barn?So, on a tactics exam, I said I would defend part of the farm complex by digging trenches in the earthen barn floor and loopholing the Victorian engineering brick barn wall, the same bricks our barracks range backstop was made of. Highly effective tactic, used extensively in Stalingrad. I might only be a Lt, but a keen student of military history. As handloader of my own ammo I also had a passable understanding of ballistics and kinetics.
A lot of houses were built with bricks burned on-site and the quality of house bricks was very variable. They were also using lime mortar until around the 1840s or '50s.
I've been told of someone being shot through a house wall with a SLR; I wasn't there so can't say it's true.
