Total War 1864-1865
2
The Civil War –Total War 1864-65Strategic Overview:
• By 1864: North attacking all forms of South’s resistance:– Military targets & field Armies prime tactical
objective– Also target South’s economy & population
• Undermine morale & psyche of South’s entire population;
• That is: North wages Total War, plan & simple!– Unmatched in Europe – even during Napoleonic
wars
3
Military Perspective• From strictly military perspective –
– South was beaten:– Time favored North’s side – to a point - why?
• Must maintain political will of the people & the voters
• South’s only chance & hope?– Delay defeat until the Nov 1864 election – Why?– Friendlier Democratic admin to negotiate treaty
terms
• North was also weary of war:– Lincoln particularly concerned about copperheads
• Democratic candidate’s stated platform position
• Lincoln's response?
4
Lincoln's response
• Promotes WHO? to General in Chief– Commands all Union Armies as a three star General– The first LT General since George Washington
• Grant takes firm control of Union Army• Pursues multi-front grand strategy:
– In stark contrast to all his predecessors – how?
• Demonstrated by Grant’s Grand Strategic Plan
5
Grant’s Grand Strategic Plan• Grant’s Grand Strategic Plan
– Grant proposes multi-front grand strategy as planned out West– Simultaneous advance on all Southern fronts– Strategy of Exhaustion andAttrition
• Aim: Press South on all fronts & deny Logistics & LOCs– Operationally: Preclude South’s use of its interior LOCs– How were LOCs used in past campaigns by South?
6
Strategic, Operational, & Tactical Goals
• Grant to Meade: Lee’s Army is your Objective.• Union Army: destroy all of South’s main armed forces:
– Strategy of attrition vice taking & holding ground;– simply put: Kill the enemy & destroy his army;
• Destroy South’s resources used to support forces:– Armies now too big to completely destroy in battle;– Therefore –must attack & destroy logistics & supply– Plus: destroy South’s means & ability to supply
• Use all available means & troops to do it:– Include all detachments & garrison troops;– Offensive advance vice garrison defense; – Grant: best defense is aggressive offense
7
Union’s Strategic Plans• North’s planned Strategic Deployments:
– Two major Union Armies advance simultaneously:
• Meade’s Army of Potomac AOP;• Sherman’s Combined Army of Cumberland,
Tennessee, Ohio
8
Strategic Deployments- The East
• Eastern Theater: Meade’s Army pursues Lee’s
• Siegle advances up Shenandoah– -fails by 15 May
– Defeated at Battle of New Market;• Butler to conduct amphibious assault &
press Richmond– Objective: cut off Richmond’s rail supply
from Petersburg•Butler soon became stalled, cut-off, &
neutralized – soon a liability
9
Strategic Deployments- The West
• Western Theater: Sherman advances on Johnston
• Banks to advance to Mobile, Alabama– Mobile’s port a key military aim
• Banks’ army diverted instead to Red River Valley– Due to political considerations & influence– Red River Valley of little strategic military
significance– By early April Banks defeated anyway!
1864 Campaigns: Strategic Overview
• Main Union Armies step off in early May, 1864:– Examine Eastern Theater Operations first

• After fruitless skirmish Grant moves back across river– Slides southeast once again around Lee’s right flank
23
Battle of Cold Harbor• Background: Series of small actions ensue:
– Grant attempts to flank Lee’s right once again – Lee anticipates & moves quicker than Grant
• Six week’s of continuous engagements occur– This series breaks previous Civil War battle
patterns:– Pattern: high casualties & no clear victory:

delay Sherman & buy time– Sherman: outflank Johnston
& destroy his army if possible• Take Atlanta & destroy Rebel
material resources
• Strategic & tactical Deployment – Union right flank Johnston’s
left– Union center & left fix South’s
position to facilitate flanking LF
31
Atlanta Campaign- execution
• Sherman presses Johnston in several actions;– Johnston maintains effective
defensive retreat– Destroys rr as he withdraws to cut
Union LOC• Sherman worries Rebel
Cavalry will cut his LOC– Sends troops to raid Mississippi as
diversion– Successfully diverts Bedford
Forrest from attacking Union LOC
• Johnston eventually runs out of room to maneuver in further retreat– NTL he is able to occupy well
fortified positions throughout
32
Atlanta Campaign- engagements• Several engagements ensue:
– Resaca, Cassville, Pickett’s Mill, & Kennesaw Mountain
• Kennesaw Mountain is first major battle of Atlanta Campaign:– Sherman attempts break
through at weak point in line
• Sherman’s Tactical objective: – Convince Johnston that his entire
line remains at risk not just his left flank
– Also wants to restore offensive spirit in his forces whose default reaction is to entrench on defense when in doubt
33
Atlanta Campaign- Kennesaw Mtn results
• Tactical, Operational, & Strategic Results:– Kennesaw Mountain: 2000
casualties & no ground gained
– Sherman reverts back to flanking movements once again
• Out of room, Johnston forced to withdraw to Atlanta:– Defend Atlanta behind its
outer fortifications
34
Battle for Atlanta- prelude
• Davis becomes more & more frustrated with Johnston’s Fabian tactics– Ultimately replaces him with Johnston’s more
aggressive subordinate- who? ?______________ – Lee had advised against this change of
command would be proved right in the end
• Commanders’ strengths & weaknesses:– Sherman: determined commander & sound
tactician– Hood: brave but impetuous- was good division
commander• Not as good an Army commander
• Force dispositions:– Hood: 40K– Sherman: 100K
35
Battle for Atlanta- Strategy & Tactics
• Strategic, Operational, & Tactical Objectives:– Hood: protect Atlanta from Union
• Destroy parts of Sherman’s army in detail
– Sherman: Destroy Hood & take Atlanta
• Plans & preparation:– Hood: takes aggressive tactical offensive
• With 40K against 100K he has to be careful
• Strategic & tactical Deployment:– Union: tactical flanking maneuvers for position;– Hood: position to strike targets of opportunity in detail
• Hood launched 3 separate engagements against Sherman – Sharply repulsed at the end of each attack– Hood is ultimately forced to withdraw behind Atlanta
defenses– He has lost more than 13K men in 9 days & nothing to show
for it
36
Siege of Atlanta• Sherman conducts quasi
siege – bombards Atlanta– Initiates turning movement to
cut Atlanta’s LOC– Union corps demonstrates to
hold Hood still
• Hood recognized Sherman’s intent too late:– His belated attempt to break
hold by attack at Jonesboro fails
– Forced to abandon city which falls Sept 2, 1864
• Hood then withdraws into Northern Alabama:– Conducts attacks on
Sherman’s LOCs to the North
37
Battle for Atlanta- Campaign Results
• Tactical, Operational, & Strategic Results:– Hood lost 15K of 40K that South can’t afford– Atlanta’s fall has major strategic
& political impact:– Lincoln’s re-election very likely– Last chance for a political
settlement evaporates
• In the meantime Grant sent ?______________ to Shenandoah Valley to halt MG Early’s successful series of attacks in the Valley & eliminate his potential threat to Washington– From Aug-Oct 1864 Sheridan would defeat
Early & become one of the Union’s best generals- Competent, aggressive, and bold
38
Sherman’s March to Sea 15 Nov – 24 Dec 1964
• Sherman detached Thomas w35K to defend TN against Hood
• Sherman finally gains Grant’s approval to abandon Atlanta– Begins his historic march
to Savannah with 60K– Sherman’s army would
destroy everything in its 60 mile wide path
• Sherman would replicate this march through Carolinas- Jan-April 1865
39
Sherman’s March- Strategic Impact
• Strategic Impact of Sherman’s March:– Destroyed South’s infrastructure
& most of it crops:• All food, rail transport, & any potential
war making resources
• Dispelled any Confederate hope of winning:– Ruined South’s morale & encouraged desertions
• Demonstrated to world especially potential Confederate allies that the North was unstoppable – North able to march through South without
opposition – And therefore likely to win only a matter of time
40
• At start of October Hood conducted raids into TN:– One of the last & riskier Confederate campaigns of war:
Hood’s Tennessee Campaign Oct - Nov 1864
41
Hood’s Tennessee Campaign- Strategy & Tactics
• Hood’s highly unrealistic Op. & strategic purpose:– Operational: recover middle Tennessee
• Cut off Sherman’s LOC from the North• No longer a real concern of Sherman- why?
– What is Sherman going to do anyway?
• Strategic: exploit potential to link up with Lee– Attack Grant with the two Armies’ combined forces– Bolster sagging Southern morale political objective
• Tactical: concentrate on portions of Union army– Defeat in detail
• Hood failed to achieve these objectives at very high cost– After losing 9K during pointless frontal assaults against well
entrenched Union positions at Franklin, he proceeds to Nashville
42
Battle of Nashville 15-16 Dec 1864
• Hood continues on with 30K to Nashville:– Even more extensively fortified– 70K Federals under Thomas fully
ready
• Hood realizes unable to attack realistically– Conducts show of siege instead
• Following ice storm, Thomas attacks:– Demonstrates to fix Hood’s attention:– Then hits Hood’s left flank
• Hood soon forced to retreat– South’s casualties: 7K to Union: 3K
– His Army ruined & no longer a credible threat to the North
43
Collapse of Confederacy –1865 • Army of Potomac continued to besiege
Petersburg– Grant continued to extend his line to the West– Added forces as they become available
• Sheridan & his cavalry were redeployed from successful operations in the Shenandoah Valley
• Grant tasked Sheridan to break Lee’s right flank:– Tactical aim: capture South Side rail junction and stop it
from supplying Petersburg
44
Road to Appomattox• Lee realized his only hope was to break free of
Grant:– Join Johnston 30K in Carolinas with Lee’s 50K– Also anticipated Grant’s intention to cut off his LOC
• Sends Pickett with 5 Brigades to meet Union threat– Able to check Sheridan’s first attack, but not the
second*
45
Battle of Five Forks
• April 1: Sheridan moved to attack Pickett at Five Forks:– Lee has charged Pickett with
holding Five Forks at all hazards– Warren’s V Corps then deployed
to attack Pickett’s center– Confederate defenses were
over extended
• Sheridan personally inspired Warren’s corps for assault– Sought to find weak spot in Rebel
line– Custer made his famous cavalry
charge on Pickett’s Right Flank– By 4:30 on 1 April 1865, Pickett’s
line crumbled
46
Fall of Petersburg & Richmond• Grant then attacked Lee all along Petersburg line:
– Forced Lee to abandon city & march to join with Johnston– Meanwhile Johnston attempted to slow Sheridan
47
Battle of Five Forks results• Tactical, Operational, & Strategic Results:
– South: 5000 out of 10K total effectives lost– North: 2500 casualties out of 25K total effectives– Resounding Tactical victory for North

48
• Grant pursued Lee aggressively:– Sent Sheridan to cut off any avenue to South
• 6 April: Union Army destroyed Early at Syler’s Creek– Eliminated Lee’s rear guard & captures 6000 Rebel prisoners
• Grant then sent surrender summons to Lee who declined
Pursuit to Appomattox
49
• April 8 eve: Sheridan positioned Army to block retreat:– Lee was completely cut-off from escape– Made one last attempt to escape & is easily repulsed
• Lee finally requested conference with Grant– Surrendered 9 April 1865 at Appomattox Court House
Surrender at Appomattox
50
Flight into Oblivion• Davis still under illusion that South can still win:
– Talked about new stage for conflict GW?:– Fled Richmond for Danville, Virginia– 10 April news reached him of Lee’s surrender:
• Started his flight into oblivion for Greensboro, NC
• Davis refused to accept reality until he read Lee’s dispatch– Johnston & Beauregard advised Davis to surrender– Davis reluctantly agreed
• Davis then tried to evade capture– 10 May: Davis captured by Federal Horsemen
• Imprisoned at Fort Monroe
– 26 May: Kirby Smith surrender last Rebel force • Marking the end of the Civil War
51
Assessment - Civil War’s Legacy
• Pivotal impact on America’s History:• Politically: extreme state’s rights destroyed
– Strong Federal central government emerged
• Society: 3.5M African Americans freed– Industrial North emerged as dominate section of Nation
• Warfare: tactical defense over tactical offense:– Armies can’t be destroyed in battle:
• Only destroyed if surrounded & surrenders Vicksburg• Or exhausted as with Hood’s at Nashville
– Strategy of Attrition pursued over Strategy of Annihilation
– Corps system becomes standard for employment• Wings- independent & self-contained
– Navy support of Army coastal & river operations proved effective
52
Assessment - 2
• Future characteristics of War - Total War:– Mass Armies employed as corps– Conscription more readily used– Mobilization of entire population & resources– All resources subject to targeting & destruction
• Industrial Revolution’s Impact:– New technologies - exploited especially by North:
• Rail, rifles, telegraph, turret guns, iron clad ships• Steam Engines refined & employed
53
Assessment – 3 Strategic & Operational Capabilities
• Lincoln superior to Davis as Commander in Chief– More effective mobilization & control of Government– Davis got bogged down in details & tended to be
ineffective
• Union & Confederate Generalship about even:– South: Lee, Jackson, Longstreet on upside
• But also Bragg & Pemberton on downside later Hood uneven
– North: Grant, Sherman, Sheridan, Hancock, Buford
• But also McClellan, Pope, Hooker, & Burnside
• Both sides employed Napoleonic Model:– Adapted to each side’s logistics requirements
54
Assessment – 4Tactical Lessons Learned
• Both sides adjusted well to new technologies:– Rifled musket & artillery – employed & exploited for
defense– Fortifications & entrenchments used more:
• Tactical defense over Tactical offense When in doubt- dig in!
• On downside: both relied on frontal assaults:– Parade dress on line assaults took heavy toll on troops– Gettysburg & Nashville & Cold Harbor
• Civil War’s Lessons Learned gradually incorporated:– LTC Upton’s tactical reforms at Spotsylvania The
Muleshoe• Column formation attack at weak salient
– Improved & more professional officer corps emerged• Improved professional military educational studies• Military Schools & War Colleges established
– U.S. Army gradually dragged into 20th century
