>He builds tunnels without noise?

Yep. Mining was a widely used siege tactic where you dig a tunnel under the enemy walls and then collapse the tunnel to bring down the wall. However, this activity could be heard from the defenders on the surface who would then dig counter mines to fight the miners.

ok but where does the lack of noise that Da Vinci was talking about come in? That shit doesn't even exist today.

I read it as him saying he had a quiet enough method that it couldn't be (easily) detected. No idea what that method was, though.

Probably something based on his other disciplines, like saturating and collapsing the ground, or a lightweight portable bronze meerkat on a stick to deflect suspicion.

"fun fact! The enemy cannot hear you mining if you simply kill them all first. Allow me to demonstrate! I shall need a volunteer..."

It’s likely to have involved some men aboveground who would, at the opportune moment, clear their throats quite loudly and boisterously - thus masking the sounds of the miners belowground.

This is total speculation, but anyway:

Underground warfare made a brief resurgence in WW1, because the front lines in Flanders were on top of soft chalk and the trench lines meant that the Western Front devolved into siege warfare. Counter-mining was also a serious concern, so the troops digging the tunnels would sometimes drill holes, soak the rock with vinegar to soften it further, then scrape away the top layer and repeat. This was a lot quieter than just hacking away with a pick.

its easy you just put pillows over the rock and the fortress thinks somebody is having a pillow fight instead of invading from underground

Salesmanship, probably. His “covered vehicle” designs don’t seem particularly practical either.

Or if merely collapsing the mine wasn't enough, they'd pack explosives in it and set them off. It's where we get the word landmine.

One of those held the record for largest non nuclear explosion for most of the 20th century.

In fact, it has a name - sapping and is done by sappers (trench diggers). Digging under enemy fortifications is called undermining and is where that word originated. Neither undermining or taking down walls was used all that often from what I've read - laying siege and starving the enemy was easier and less deadly (and if that fails, salt their fields and poison their wells before you leave...).

Probably well known because it was used in some extremely famous sieges. Constantinople, Siege of Vienna etc
