But they didn't.

Flushed with their victories at Fort Henry and Fort Donelson and the capture of Nashville, and the whole State of Tennessee having fallen into their hands, victory was again to perch upon their banners, for Buell's army, by forced marches, had come to Grant's assistance at the eleventh hour.
Gunboats and transports were busily crossing Buell's army all of Sunday night.

We could hear their boats ringing their bells, and hear the puff of smoke and steam from their boilers.

Our regiment was the advance outpost, and we saw the skirmish line of the Federals advancing and then their main line and then their artillery.

We made a good fight on Monday morning, and I was taken by surprise when the order came for us to retreat instead of advance.
