The
way the story is usually told is that only after realizing his Desoto
canal would not work, did Major General Ulysses Simpson Grant turn
to the Lake Providence canal, 40 miles upstream from Young's Point.
In fact, in early January Grant had dispatched a small battalion of
engineers all across the region, seeking someway, anyway to get
around or at Vicksburg. The Desoto canal was the just the most
obvious choice. But it would have saved a lot of time and energy had
those engineers known how the Mississippi River formed Lake
Providence in the first place But that would have to wait a couple
of generations for students of geology and
fluviomorphology to learn their trade.
Dig
into the mud of the of Lower Mississippi and beneath 35 feet of river
deposits you will find 50 feet and more of yellow sand, the bottom of
the 400 mile long Mississippi Embayment, an arm of the ancient Tethys
Ocean, which followed the crack of the New Madrid rift valley into
the very center of North America, as far north as present day Cairo,
Illinois. Over most the last 100 million years this was a backwater,
while American's most powerful rivers, like the Teays in Ohio and
Indiana and the New River of Virginia, flowed northwest from the
Himalayan heights of the Appalachian Mountains to the Arctic Sea.
Then, 2.5 million years ago the first of the Laurentide glaciers
blocked those rivers, forcing them south and into the bay.
About
8,000 years ago, the glacial river Warren breached the last of the
ice dams at what is today the Wisconsin Dells, and blazed a path
which the Illinois River followed, southward, joining the ancient
Ohio in filling the 450 mile bay with that 35 feet of river
sediments.
Flowing
across this ancient silted up bay, Old Man river meanders at an
average speed of one and one-half miles an hour, losing just 3 tenths
of a vertical inch for every horizontal mile south. With such a slow
current, any minor impediment will magnify current variations. Where
the current is slightly faster, it eats into the bank. Where the
current is a little slower it drops sediments, building up the bank.
Over time this creates a curving meander, with the stronger current
shifting from the inside at the base of the curve to the outside at
its height.
But
the current eventually cuts across the base of these meanders,
isolating each as an oxbow lake. Each spring flood piles more
sediments against the abandoned meander. By 1863, when the
Scottish
minister's son and 40 year old artilleryman, Lieutenant Colonel
William Latimer Duff arrived to investigate, Lake Providence was a
six mile long oxbow, a full mile from the river's new course, and
usually 8 feet lower. So a mile long canal, 100 feet wide and 5 feet
deep, connecting the Mississippi to Lake Providence would get
Grant's army 7 miles inland from the Mississippi.
And
from there, said Lt. Colonel Duff, who had made the trip, it was
relatively easy. From Lake Providence it was another short mile to
the Bushy Bayou, (above) which connected to the sinuous Baxter Bayou, which
connected to the 6 mile long Bayou Macon which passed through a cypress swamp. Trees would have to be cleared here, but the swamp fed the Tensas River, which split
into the Ouachita River before flowing into the Black River, which
flowed into the Red River of the South which finally rejoined the
Mississippi River 400 miles south, just below Natchez. As Private and
hospital steward Charles Allaire, noted , it seemed, "a long way
around 'Robin Hood's Barn'," But such was Grant's desperation to get to Vicksburg.
The
new operation began on Tuesday, 3 February, 1863, when Colonel, soon
to be Brigadier General, 36 year old George Washington Deitzler was
given the task of starting the Lake Providence canal. Shortly there
after the 32,000 men of the 17th Crops of the Army of Tennessee under
34 year old General James Birdseye McPherson, were brought in to
begin deepening and widening Bushy and Baxter Bayous. Colonel
Deitzler, thought it would take no more than 6 days to dig the first
mile long canal. After that, "I do not think that we will have
any considerable difficulty in finding a passage for gunboats and
small stern-wheel boats through Baxter Bayou and Bayou Macon, a
distance of from 10 to 15 miles...it will only be necessary to cut a
few trees...Once in Bayou Macon, we shall have a clear coast to (the)
Red River." He optimistically figured the entire effort would
take no more than 3 weeks.
Amazingly
the causality rate for the 17th Corps never approached that of its
less fortunate comrades working on the Desoto canal. Partly this was
because McPherson's camps were on high ground, a mile away from the
river, and they were well "policed", meaning clean. But
mostly it was because the actual effort back in Bushy and Baxter
Bayous was preformed by freed slaves. They were paid for their work,
and fed a standard army diet. But no one thought them important to
record their death rates. The soldiers spent their time drilling,
playing baseball, and raiding the surrounding plantations for food
and souvenirs.
And
in this place the February floods worked in the army's favor. The
river was now 15 higher than Lake Providence, and when the coffer dam
at the head of the canal was breached on Tuesday, 17 March (above), the
water gushed into the lake, even sweeping away a small town on the
Mississippi's banks. By Monday, 23 March the lake had so over flowed
its banks, as to eliminate the need for a connecting canal to Bushy
Bayou.
Grant
took over a lake shore mansion in early March to inspect the effort.
And while he was duly impressed with the progress he told Washington
that, "...there was scarcely a chance of this ever becoming a
practicable route for moving troops through an enemy's country."
On those narrow bayous, just felling a few trees could chock off
the entire army. But more importantly there was the problem of what
happened if and when Grant's army reached Natchez. Because there
Grant would face an even greater threat than presented by the
Illinois political General, John Alexander McClernand - the
very, very ambitious politician, 46 year old Major General Nathaniel
Prentiss Banks.
Nathaniel
Banks (above) was an actual self-made man, having started as a bobbin boy in
a Massachusetts textile mill and risen by his own initiative until,
at 34 years of age, he was elected Speaker of the U.S. House
of Representatives, and at 46, Governor of Massachusetts. While in
that office Banks made compromises with the anti-Catholic Know
Nothing Party, and in 1860 this cost him support when he briefly
contested Lincoln for the Presidential nomination. Banks' dominant
characteristic was his ambition, which burned with such a flame that
it often snuffed out every other spark within him.
With
the start of the Civil War, Lincoln appointed Banks a Major General
of Volunteers, because of his ability to inspire New England men to
enlist. But it was General Nathaniel Banks who brought rebellious
Baltimore under control, and kept Maryland in the union during the
most dangerous year of 1861. So, despite concerns from West Point
trained officers, in February of 1862 Banks was sent to clear out the
rebels from the southern Shenandoah Valley. Instead, by the end of
May, rebel general "Stonewall" Jackson had driven Bank's
army completely out of the Valley.
Banks
managed to avoid any blame for that disaster, and was given command
of an entire wing of the short lived Federal Army of Virginia, under
the pompous General John Pope. On Saturday, 9 August, 1862, left
isolated in northern Virginia, and facing a much larger rebel force,
again under Jackson, Banks attacked at Cedar Mountain (above). His audacity
caught Jackson off guard, and he damn near drove "Stonewall"
from the field. But the rebels rallied and at the end of the day it was Banks who was
forced to repeat. One of his West Point trained officers described
the battle, "...as
great a piece of folly as I have ever witnessed on the part of an
incompetent general." And for an officer in the sad and misused
eastern armies, that was saying quite a bit.
Luckily
Banks was slightly wounded in the engagement, and a brief
hospitalization allowed his superiors to replace him. Then, in
November, Lincoln turned to Nathaniel Banks again to recruit 30,000
new soldiers to form the new Army of the Gulf. Before the men had
even began their training they and their commander were dispatched to
New Orleans, to replace the even more incompetent political Major
General, Benjamin Butler.
Banks
was under orders to, as soon as possible, attack and capture the
rebel fortress of Fort Hudson, just 20 miles north of the Yankee
lines at Baton Rouge, and to then to advance on Vicksburg to assist
Major General Grant. But Banks' little Army of the Gulf needed time
to complete their training, and their equipment was slow in following
them. Besides, the faster Banks moved north, the sooner he would fall
under Grant's command.
Still, he did lead 12,000 men out of Baton
Rouge toward Fort Hudson, on the unfortunate date of Friday, the 13th
of March, 1863. The effort was a "Mud March" without the mud. It failed before it ever got within sight of
the fort because of bad maps and bad communications with
Admiral Farragut's ships, which were supposed to provide artillery
support. And, of course, Nathaniel Banks
could see no political advantage in helping someone else win a
battle.
Perhaps
it was this minor fiasco which convinced Grant that risking the maze
of the Louisiana swamps just to meet up with Banks, was not a likely
way to capture Vicksburg. Besides, he still had other options. On
the same day when Grant had ordered work to begin on the Lake
Providence Canal, further up the Mississippi River, 400 Federal
soldiers were dismantling a levee at a place called the "Yazoo
Pass", on the Coldwater River (below).
