What does Strike the Tent mean?

It is a quote attributed to Robert E Lee as his last Words. "Strike the tent" would be an order to take down or disassemble the tent. It would seem that Lee was being metaphorical at the time, since he was about to die and the "tent" (his life) was about to end.

It was the last order that General Lee gave as commander of Confederate forces after the surrender at Appomattox Court House. At any rate, the idea that General Lee was musing metaphorically upon his deathbed is absurd.
