I am still doubtful, when coal is a little hard to get burning on its
own. Add some oil though and you will have your underground fire in no
time.

So you can just imagine the US Army packing thousands of oil drums
into a coal mine, then it is "whoops" some soldier dropped a match.

And you evidence for this is... what?

Underground coal fires are almost impossible to put out even after *decades*.
Why should you need oil to get them going?
