The Battle of Cold Harbor was fought from May 31 to June 12, 1864, with the most significant fighting occurring on June 3. It was one of the final battles of Union Lt. Gen. Ulysses S. Grant's Overland Campaign during the American Civil War, and is remembered as one of American history's bloodiest, most lopsided battles. Thousands of Union soldiers were killed or wounded in a hopeless frontal assault against the fortified positions of Confederate Gen. Robert E. Lee's army. On May 31, as Grant's army once again swung around the right flank of Lee's army, Union cavalry seized the crossroads of Old Cold Harbor, about 10 miles northeast of the Confederate capital of Richmond, Virginia, holding it against Confederate attacks until the Union infantry arrived. Both Grant and Lee, whose armies had suffered enormous casualties in the Overland Campaign, received reinforcements. On the evening of June 1, the Union VI Corps and XVIII Corps arrived and assaulted the Confederate works to the west of the crossroads with some success. On June 2, the remainder of both armies arrived and the Confederates built an elaborate series of fortifications 7 miles long. At dawn on June 3, three Union corps attacked the Confederate works on the southern end of the line and were easily repulsed with heavy casualties. Attempts to assault the northern end of the line and to resume the assaults on the southern were unsuccessful. Grant said of the battle in his memoirs, "I have always regretted that the last assault at Cold Harbor was ever made. ... No advantage whatever was gained to compensate for the heavy loss we sustained." The armies confronted each other on these lines until the night of June 12, when Grant again advanced by his left flank, marching to the James River. It was an impressive defensive victory for Lee, but it was his last in the war. In the final stage, he alternated between digging into the trenches at Petersburg and fleeing westward across Virginia. ==Background== Grant's Overland Campaign was one of a series of simultaneous offensives the newly appointed general in chief launched against the Confederacy. By late May 1864, only two of these continued to advance: Maj. Gen. William T. Sherman's Atlanta Campaign and the Overland Campaign, in which Grant accompanied and directly supervised the Army of the Potomac and its commander, Maj. Gen. George G. Meade. Grant's campaign objective was not the Confederate capital of Richmond, but the destruction of Lee's army. President Abraham Lincoln had long advocated this strategy for his generals, recognizing that the city would certainly fall after the loss of its principal defensive army. Grant ordered Meade, "Wherever Lee goes, there you will go also."〔Hattaway & Jones, p. 525; Trudeau, pp. 29–30.〕 Although he hoped for a quick, decisive battle, Grant was prepared to fight a war of attrition. Both Union and Confederate casualties could be high, but the Union had greater resources to replace lost soldiers and equipment.〔Eicher, pp. 661–62; Kennedy, p. 282; Jaynes, pp. 25–26; Rhea, p. 369; Grimsley, pp. 94–110, 118–29, provides details on the failed campaigns (the Bermuda Hundred Campaign and Franz Sigel's campaign in the Shenandoah Valley) that were part of Grant's "peripheral strategy."〕 On May 5, after Grant's army crossed the Rapidan River and entered the Wilderness of Spotsylvania, it was attacked by Lee's Army of Northern Virginia. Although Lee was outnumbered, about 60,000 to 100,000, his men fought fiercely and the dense foliage provided a terrain advantage. After two days of fighting and almost 29,000 casualties, the results were inconclusive and neither army was able to obtain an advantage. Lee had stopped Grant, but had not turned him back; Grant had not destroyed Lee's army. Under similar circumstances, previous Union commanders had chosen to withdraw behind the Rappahannock, but Grant instead ordered Meade to move around Lee's right flank and seize the important crossroads at Spotsylvania Court House to the southeast, hoping that by interposing his army between Lee and Richmond, he could lure the Confederates into another battle on a more favorable field.〔Salmon, p. 253; Kennedy, pp. 280–82; Eicher, pp. 663–71; Jaynes, pp. 56–81.〕 Elements of Lee's army beat the Union army to the critical crossroads of Spotsylvania Court House and began entrenching, a tactic that became increasingly essential for the outnumbered defenders.〔Earl J. Hess, ''Trench Warfare Under Grant and Lee: Field Fortifications in the Overland Campaign'' (2007)〕 Meade was dissatisfied with Maj. Gen. Philip Sheridan's Union cavalry's performance and released it from its reconnaissance and screening duties for the main body of the army to pursue and defeat the Confederate cavalry under Maj. Gen. J.E.B. Stuart. Sheridan's men mortally wounded Stuart in the tactically inconclusive Battle of Yellow Tavern (May 11) and then continued their raid toward Richmond, leaving Grant and Meade without the "eyes and ears" of their cavalry.〔Jaynes, pp. 82–86, 114–24; Eicher, pp. 673–74; Salmon, pp. 270–71, 279–83; Kennedy, pp. 283, 286.〕 Near Spotsylvania Court House, fighting occurred on and off from May 8 through May 21, as Grant tried various schemes to break the Confederate line. On May 8, Union Maj. Gens. Gouverneur K. Warren and John Sedgwick unsuccessfully attempted to dislodge the Confederates under Maj. Gen. Richard H. Anderson from Laurel Hill, a position that was blocking them from Spotsylvania Court House. On May 10, Grant ordered attacks across the Confederate line of earthworks, which by now extended over 4 miles (6.5 km), including a prominent salient known as the Mule Shoe. Although the Union troops failed again at Laurel Hill, an innovative assault attempt by Col. Emory Upton against the Mule Shoe showed promise.〔Salmon, pp. 271–75; Kennedy, p. 285; Eicher, pp. 671–73, 675–76.〕 Grant used Upton's assault technique on a much larger scale on May 12 when he ordered the 15,000 men of Maj. Gen. Winfield S. Hancock's corps to assault the Mule Shoe. Hancock was initially successful, but the Confederate leadership rallied and repulsed his incursion. Attacks by Maj. Gen. Horatio G. Wright on the western edge of the Mule Shoe, which became known as the "Bloody Angle," involved almost 24 hours of desperate hand-to-hand fighting, some of the most intense of the Civil War. Supporting attacks by Warren and by Maj. Gen. Ambrose Burnside were unsuccessful. In the end, the battle was tactically inconclusive, but with almost 32,000 casualties on both sides, it was the costliest battle of the campaign. Grant planned to end the stalemate by once again shifting around Lee's right flank to the southeast, toward Richmond.〔Salmon, pp. 275–79; Kennedy, pp. 285–86; Eicher, pp. 676–79; Jaynes, pp. 124–30.〕 Grant's objective following Spotsylvania was the North Anna River, about south. He sent Hancock's Corps ahead of his army, hoping that Lee would attack it, luring him into the open. Lee did not take the bait and beat Grant to the North Anna. On May 23, Warren's V Corps crossed the river at Jericho Mills, fighting off an attack by A.P. Hill's corps, while Hancock's II Corps captured the bridge on the Telegraph Road. Lee then devised an ingenious plan, which represented a significant potential threat to Grant: a five-mile (8 km) line that formed an inverted "V" shape with its apex on the river at Ox Ford, the only defensible crossing in the area. By moving south of the river, Lee hoped that Grant would assume that he was retreating, leaving only a token force to prevent a crossing at Ox Ford. If Grant pursued, the pointed wedge of the inverted V would split his army and Lee could concentrate on interior lines to defeat one wing; the other Union wing would have to cross the North Anna twice to support the attacked wing.〔Welcher, 980; Grimsley, p. 141; Salmon, p. 285; Kennedy, p. 289; Trudeau, pp. 236, 241.〕 Grant almost fell into Lee's trap. He assaulted the tip of the apex at Ox Ford and the right wing of the V, but Lee, who was incapacitated in his tent by diarrhea, could not coordinate the attack he planned to make, losing a golden opportunity. Grant finally realized the situation he faced with a divided army and ordered his men to stop advancing and to build earthworks of their own. However, the Union general remained optimistic. He was convinced that Lee had demonstrated the weakness of his army by not attacking when he had the upper hand. He wrote to the Army's chief of staff, Maj. Gen. Henry W. Halleck: "Lee's army is really whipped. ... I may be mistaken but I feel that our success over Lee's army is already assured."〔Jaynes, p. 137; Trudeau, p. 239; Grimsley, pp. 145–48; Esposito, text for map 135.〕 As he did after the Wilderness and Spotsylvania, Grant planned another wide swing around Lee's flank, marching east of the Pamunkey River to screen his movements from the Confederates. His army disengaged on May 27 and crossed the river. Lee moved his army swiftly in response, heading for Atlee's Station on the Virginia Central Railroad, a point only 9 miles north of Richmond. There, his men would be well-positioned behind a stream known as Totopotomoy Creek to defend against Grant if he moved against the railroads or Richmond. Lee was not certain of Grant's specific plans, however; if Grant was not intending to cross the Pamunkey in force at Hanovertown, the Union army could outflank him and head directly to Richmond. Lee ordered cavalry under Maj. Gen. Wade Hampton to make a reconnaissance in force, break through the Union cavalry screen, and find the Union infantry.〔Rhea, pp. 32–37, 41–44, 50–57; Eicher, pp. 671, 679, 683; Salmon, p. 288; Furgurson, pp. 43–47; Grimsley, pp. 149–51.〕 On May 28, Hampton's troopers encountered Union cavalry under Brig. Gen. David McM. Gregg in the Battle of Haw's Shop. Fighting predominately dismounted and utilizing earthworks for protection, neither side achieved an advantage. The battle was inconclusive, but it was one of the bloodiest cavalry engagements of the war. Hampton held up the Union cavalry for seven hours, prevented it from achieving its reconnaissance objectives, and had provided valuable intelligence to Lee about the disposition of Grant's army.〔Jaynes, p. 149; Furgurson, pp. 49–52; Salmon, p. 288; Grimsley, pp. 151–52; Rhea, pp. 68–71, 87–88.〕 After Grant's infantry had crossed to the south bank of the Pamunkey, Lee saw an opportunity on May 30 to attack Warren's advancing V Corps with his Second Corps, now commanded by Lt. Gen. Jubal Early. Early's divisions under Maj. Gens. Robert E. Rodes and Stephen Dodson Ramseur drove the Union troops back in the Battle of Bethesda Church, but Ramseur's advance was stopped by a fierce stand of infantry and artillery fire. On that same day, a small cavalry engagement at Matadequin Creek (the Battle of Old Church) drove an outnumbered Confederate cavalry brigade to the crossroads of Old Cold Harbor, verifying to Lee that Grant intended to move toward that vital intersection beyond Lee's right flank, attempting to avoid another stalemate on the Totopotomoy Creek line.〔Grimsley, pp. 156–59; Kennedy, pp. 290–91; Salmon, pp. 290–94.〕 Lee received notice that reinforcements were heading Grant's way from Bermuda Hundred. The 16,000 men of Maj. Gen. William F. "Baldy" Smith's XVIII Corps were withdrawn from Maj. Gen. Benjamin Butler's Army of the James at Grant's request, and they were moving down the James River and up the York to the Pamunkey. If Smith moved due west from White House Landing to Old Cold Harbor, southeast of Bethesda Church and Grant's left flank, the extended Federal line would be too far south for the Confederate right to contain. Smith's men arrived at White House May 30–31. One brigade was left behind on guard duty, but about 10,000 men arrived to join Grant's army about 3 p.m. on June 1.〔King, pp. 295–96; Welcher, pp. 986–87; Kennedy, p. 291.〕 Lee also received reinforcements. Confederate President Jefferson Davis directed Gen. P.G.T. Beauregard to send the division of Maj. Gen. Robert F. Hoke, over 7,000 men, from below the James River. (The first troops of Hoke's division arrived at Old Cold Harbor on May 31, but were unable to prevent the Union cavalry from seizing the intersection.) With these additional troops, and by managing to replace many of his 20,000 casualties to that point in the campaign, Lee's Army of Northern Virginia had 59,000 men to contend with Meade's and Grant's 108,000.〔 But the disparity in numbers was no longer what it had been—Grant's reinforcements were often raw recruits and heavy artillery troops, pulled from the defenses of Washington, D.C., who were relatively inexperienced in infantry tactics, while most of Lee's had been veterans moved from inactive fronts, and who were soon entrenched in impressive fortifications.〔Furgurson, pp. 58–60; Rhea, pp. 13, 162; Kennedy, p. 291.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Battle of Cold Harbor」の詳細全文を読む スポンサード リンク
