During the Second Day of the Battle of Gettysburg (July 2, 1863) Confederate Gen. Robert E. Lee attempted to capitalize on his first day's success. He launched the Army of Northern Virginia in multiple attacks on the flanks of the Union Army of the Potomac, commanded by Maj. Gen. George G. Meade. After a short delay to assemble his forces and avoid detection in his approach march, Lt. Gen. James Longstreet attacked with his First Corps against the Union left flank. His division under Maj. Gen. John Bell Hood attacked Little Round Top and Devil's Den. To Hood's left, Maj. Gen. Lafayette McLaws attacked the Wheatfield and the Peach Orchard. Although neither prevailed, the Union III Corps was effectively destroyed as a combat organization as it attempted to defend a salient over too wide a front. Gen. Meade rushed as many as 20,000 reinforcements from elsewhere in his line to resist these fierce assaults. The attacks in this sector concluded with an unsuccessful assault by the Third Corps division of Maj. Gen. Richard H. Anderson against the Union center on Cemetery Ridge. That evening, Confederate Second Corps commander Lt. Gen. Richard S. Ewell turned demonstrations against the Union right flank into full-scale assaults on Culp's Hill and East Cemetery Hill, but both were repulsed. The Union army had occupied strong defensive positions, and Meade handled his forces well, resulting in heavy losses for both sides but leaving the disposition of forces on both sides essentially unchanged. Lee's hope of crushing the Army of the Potomac on Northern territory was dashed, but undaunted, he began to plan for the third day of fighting. This article includes details of many attacks on the Union left flank (Devil's Den, the Wheatfield, and the Peach Orchard) and center (Cemetery Ridge), but separate articles describe other major engagements in this massive battle of the second day: * Little Round Top * Culp's Hill * Cemetery Hill ==Lee's plan and movement to battle== By the morning of July 2, six of the seven corps of the Army of the Potomac had arrived on the battlefield. The I Corps (Maj. Gen. John Newton, replacing Abner Doubleday) and the XI Corps (Maj. Gen. Oliver O. Howard) had fought hard on the first day, and they were joined that evening by the XII Corps (Maj. Gen. Henry W. Slocum), III Corps (Maj. Gen. Daniel E. Sickles), and II Corps (Maj. Gen. Winfield S. Hancock), and on the morning of July 2 by the V Corps (Maj. Gen. George Sykes). The VI Corps (Maj. Gen. John Sedgwick) was still 30 miles (50 km) away in Manchester, Maryland, on that morning. They assumed positions in a fish hook shape about three miles (5 km ) long, from Culp's Hill, around to Cemetery Hill, and down the spine of Cemetery Ridge. The Army of Northern Virginia line was roughly parallel to the Union's, on Seminary Ridge and on an arc northwest, north, and northeast of the town of Gettysburg. All of the Second Corps (Lt. Gen. Richard S. Ewell) and Third Corps (Lt. Gen. A.P. Hill) were present, and the First Corps (Lt. Gen. James Longstreet) was arriving from Cashtown; only Longstreet's division under George E. Pickett did not participate in the battle on July 2.〔Pfanz, ''Battle of Gettysburg'', p. 21. Eicher, p. 521. Pfanz, ''Second Day'', pp. 55-81.〕 Robert E. Lee had several choices to consider for his next move. His order of the previous evening that Ewell occupy Culp's Hill or Cemetery Hill "if practicable" was not realized, and the Union army was now in strong defensive positions with compact interior lines. His senior subordinate, Longstreet, counseled a strategic move—the Army should leave its current position, swing around the Union left flank, and interpose itself on Meade's lines of communication, inviting an attack by Meade that could be received on advantageous ground. Longstreet argued that this was the entire point of the Gettysburg campaign, to move strategically into enemy territory but fight only defensive battles there. Lee rejected this argument because he was concerned about the morale of his soldiers having to give up the ground for which they fought so hard the day before. He wanted to retain the initiative and had a high degree of confidence in the ability of his army to succeed in any endeavor, an opinion bolstered by their spectacular victories the previous day and at Chancellorsville. He was therefore determined to attack on July 2.〔Pfanz, ''Battle of Gettysburg'', p. 21. Pfanz, ''Second Day'', pp. 26-29.〕 Lee wanted to seize the high ground south of Gettysburg, primarily Cemetery Hill, which dominated the town, the Union supply lines, and the road to Washington, D.C., and he believed an attack up the Emmitsburg Road would be the best approach. He desired an early-morning assault by Longstreet's Corps, reinforced by Ewell, who would move his Corps from its current location north of town to join Longstreet. Ewell protested this arrangement, claiming his men would be demoralized if forced to move from the ground they had captured.〔Pfanz, ''Second Day'', pp. 61, 111-12.〕 And Longstreet protested that his division commanded by John Bell Hood had not arrived completely (and that Pickett's division had not arrived at all).〔Pfanz, ''Second Day'', p. 112.〕 Lee compromised with his subordinates. Ewell would remain in place and conduct a demonstration (a minor diversionary attack) against Culp's Hill, pinning down the right flank of the Union defenders so that they could not reinforce their left, where Longstreet would launch the primary attack as soon as he was ready. Ewell's demonstration would be turned into a full-scale assault if the opportunity presented itself.〔Pfanz, ''Second Day'', pp. 113-14.〕 Lee ordered Longstreet to launch a surprise attack with two divisions straddling, and guiding on, the Emmitsburg Road.〔Pfanz, ''Second Day'', p. 153.〕 Hood's division would move up the eastern side of the road, Lafayette McLaws's the western side, each perpendicular to it. The objective was to strike the Union Army in an oblique attack, rolling up their left flank, collapsing the line of Union corps onto each other, and seizing Cemetery Hill.〔Harman, p. 27.〕 The Third Corps division of Richard H. Anderson would join the attack against the center of the Union line on Cemetery Ridge at the appropriate time. This plan was based on faulty intelligence because of the absence of J.E.B. Stuart and his cavalry, leaving Lee with an incomplete understanding of the position of his enemy. He believed that the left flank of the Union army was adjacent to the Emmitsburg Road hanging "in the air" (unsupported by any natural barrier), and an early morning scouting expedition seemed to confirm that.〔Pfanz, ''Second Day'', pp. 106-07.〕 In reality, by dawn of July 2 the Union line stretched the length of Cemetery Ridge and anchored at the foot of the imposing Little Round Top. Lee's plan was doomed from its conception, as Meade's line occupied only a small portion of the Emmitsburg Road near the town itself. Any force attacking up the road would find two entire Union corps and their guns posted on the ridge to their immediate right flank. By midday, however, Union general Sickles would change all that.〔Hall, pp. 89, 97.〕 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 Gettysburg, Second Day」の詳細全文を読む スポンサード リンク
