... a few hours notice of an invasion?

Well, I guess 80 hours is "a few" in your book. Robert Chew arrived in Charleston at 6 PM on the 8th, met with Pickens, delivered Lincoln's message, and was back on the train north at 11 PM.

And the invasion began three days later, but a day late due to the storm.

So, let’s see, 80 minus 10 and 1/2, minus 24....well you do the math.
