Losing the Cairo: A Yankee Pilot Recalls the Yazoo Disaster
In December 1862, the Federal armies based in western Tennessee and Mississippi stood poised to embark on one of the most critical operations of the war: the assault on the Mississippi River bastion of Vicksburg. General U.S. Grant and his army was already busily preparing for a multi-front drive on Vicksburg, one of the key elements of which was a water-borne assault on the northern flank of the city via the Yazoo River. To ensure that Federal troops could safely enter the area, the brown water Navy engaged in frequent patrols of the Yazoo.
Among those sailing upon the Yazoo River was an Ohioan who was intimately familiar with the region. His name was John F. Morton. Prior to the war, Morton had worked the Yazoo for eight years as a pilot aboard several steamboats and as such knew the river as well as anyone in Federal uniform. Morton had been assigned as a special pilot to the Mississippi Squadron in August 1862, having previously served as a lieutenant in the 56th Ohio Infantry.
In the following extraordinary letter, Morton describes discovering Confederate torpedoes in the Yazoo and was aboard the U.S.S. Cairo the following day engaged in what might be the first mine-sweeping operation ever conducted by the U.S. Navy. Despite their best efforts, the Cairo detonated one of the torpedoes and sank within minutes.
Mississippi Squadron, off the Yazoo River, Mississippi
December 13, 1862
Since we have been down here, we have been sent up the Yazoo River every two or three days to within two or three miles of a battery on that river 25 miles from the Mississippi. Nothing of note occurred until the 11th instant when we were ordered to proceed up the Yazoo with the light gunboats Marmora and Signal. When within about four miles of the battery, I noticed something like the bottom of a chair floating bottom up, the legs attached together to each other with wires. I was heading directly for it, being in the channel, but as I neared it I thought I would not run over it, so I slacked steam and sheered around it, passing within three feet of it. I called the attention of the Captain to it and at this I was observed in the river above quite a number of floats and other suspicious things which did not belong there. I then stopped the boat and the officers examined with their glasses.
While
doing this, there was quite an eruption in the water near the Signal in
the rear. This convinced the Captain that these floats were torpedoes; we then
rounded down the river. As we passed the chair bottom we met going up and after
we had passed some 100 yards, a musket shot was fired into it and one of the
most terrific explosions ensued which I have ever witnessed and in fact even
more terrible than I would have thought possible. It shocked the boat very
much, throwing the water out of the water tank and rushed the water up so high
that it ran into the boat’s hold at the tiller holes at the head of the rudder
stalk, breaking all the glass on the boat very nearly and throwing a sheet of
flames nearly as high as the hurricane roof of the boat and throwing a conical
shot high into the air. The boat, however, was not hurt.

We
safely returned to the fleet at the mouth of the river and the Captain reported
to Commodore Walke. On the morning of the 12th, the ironclad
steamers Cairo and Pittsburgh and the light boats Marmora and
Signal were ordered to proceed up the Yazoo, draw up these torpedoes,
and destroy them. The Cairo being the flagship in this expedition, I was
ordered on board of her. We proceeded without opposition up the Yazoo until we
reached the hornet’s nest of torpedoes. After shelling the woods in the
vicinity to prevent the small boats being fired on from shore, the boat was
manned, sent out and took up two torpedoes. Previous to this the captain of the
Cairo had asked me to come out of the pilothouse and show him what I
could and what I had learned of them the day previous.
After
taking up three of them we all looked carefully forward but could see nothing
for some 200 yards. The Captain ordered the Marmora to proceed up the
left-hand shore carefully while we went up the right. We were going slowly,
watching the water closely, but could see no float or anything indicating a
torpedo when all at once, I felt a severe shock, terrible indeed. I was
standing directly over the port bow when it exploded and was thrown upon a pile
of iron some six or eight feet distant and of some height. The blow stunned me
for a few moments but didn’t seriously wound me though I was badly bruised. The
engineer was badly hurt and two or three sailors also. This amounts to almost
all the personal injuries. The boat sank in eight minutes after the explosion
at 11;25 in the morning in 25 feet of water; nothing was saved from her. Thus,
we lost one of the finest and best boats of our fleet. After this there were 11
of the torpedoes taken out of the river without further injury.
