Re: "I'm sure we'll lose the records of it in the fire, though...""
There's a story from Afghanistan of a unit digging a latrine and finding a buried connex full of weapons.
Thinking it was some special forces secret weapons cache they called an officer who was confused.
He called a sergeant who said he would deal with it. He ordered another group to bury it somewhere else.
What he suspected had happened was a container of weapons were delivered which hadn't been ordered and didn't have paperwork for - so rather than try and sort it out, a previous sergeant had simply buried the mistake and he was continuing the good work.
I'm now suspecting that archaeological finds are actually a bunch of stuff that the Roman Empire sent by mistake and an old hand centurion buried rather than try and sort out the stylus work.
