[SPOILER] Engineer's last speech

[blackdawg47]

Can someone please clarify some events that the engineer is referring to?

I have stood knee deep in mud and bone, and filled my lungs with mustard gas. - Probably something about Hitler.

I have seen two brothers fall. - Which brothers?

I have lain with holy wars and copulated with the autumnal fallout. - The crusades?

I have dug trenches for the refugees; - World Wars I think..

I have murdered dissidents where the ground never thaws, and starved the masses into faith. - Religious oppression?

A child's shadow burnt into the brickwork. - What child?

A house of skulls in the jungle. - Aztec massacre?

The innocent, the innocent, Mandus, trod and bled and gassed and starved and beaten and murdered and enslaved. This is your coming century! They will eat them Mandus, they will make pigs of you all and they will bury their snouts into your ribs and they will eat your hearts!
