Did Robert E. Lee actually say this?

Editor's note: Does anyone have documentation that proves Robert E. Lee actually said this?

"It appears we've appointed our worst generals to command forces, and our most gifted and brilliant to edit newspapers. In fact, I discovered by reading newspapers that these journalist- geniuses plainly saw all my strategic defects from the start, yet failed to inform me until it was too late. Accordingly, I'm readily willing to yield my command to these obviously superior intellects, and I'll, in turn, do my best for the cause by writing editorials, after the fact."

- Robert E. Lee, 1863.
