I recently came across this video:

It's from a Danish television production about the Second Schleswig War (1864). It comes pretty close to how I always imagined the Safehold artillery bombardments, so I wanted to share it.

2nd World War artillery footage is obviously too advanced, and 1st World War artillery footage didn't feel right to me either, but this... kinda captures my imagination perfectly.
