He granted the request.

With "Doc," revolver in hand, watching him, Williams walked to the outer edge of the floor.
Suddenly he made a spring to the right and was out of sight in the black darkness before his guard could even raise his revolver.
"Doc" leaped after him, firing just as he rounded the corner of the cabin.

The report brought us all to our feet.

I at once covered Bevins with my revolver, but, seeing that he could barely stir, I lowered it.
Then in came "Doc," swearing a blue streak and announcing that Williams had escaped.

Nothing was left us but to gather our horses close to the cabin and stand guard the rest of the night to prevent the possibility of our late prisoner sneaking in and getting away with one of them.
This was the last I ever saw or heard of Williams, but we got back to Fort Lyon with Bevins.
Though we had lost one of our prisoners, General Carr complimented us on the success of our trip.
