In the ninth and tenth grades, students take "pre-diploma" classes that prepare them for classes in the IB program. In the eleventh and twelfth grades, students take six IB classes and have

504-594: A bayonet charge by the 20th Maine , ordered by Colonel Joshua L. Chamberlain and possibly led down the slope by Lieutenant Holman S. Melcher , was one of the most fabled episodes in the Civil War and propelled Chamberlain into prominence after the war. Ewell interpreted his orders as calling only for a cannonade. His 32 guns, along with A. P. Hill's 55 guns, engaged in a two-hour artillery barrage at extreme range that had little effect. Finally, about six o'clock, Ewell sent orders to each of his division commanders to attack

630-455: A brigade of New Yorkers under Brigadier General George S. Greene behind strong, newly constructed defensive works. With reinforcements from the I and XI corps, Greene's men held off the Confederate attackers, though giving up some of the lower earthworks on the lower part of Culp's Hill.

The Pennsylvania General Assembly met in

882-453: A controversial move, Lee allowed Stuart to take a portion of the army's cavalry and ride around the east flank of the Union army. Lee's orders gave Stuart much latitude, and both generals share the blame for the long absence of Stuart's cavalry, as well as for the failure to assign a more active role to the cavalry left with the army. Stuart and his three best brigades were absent from the army during

1008-568: A dawn artillery bombardment against the Confederates on Culp's Hill in an effort to regain a portion of their lost works. The Confederates attacked, and the second fight for Culp's Hill ended around 11   a.m. Harry Pfanz judged that, after some seven hours of bitter combat, "the Union line was intact and held more strongly than before". Lee was forced to change his plans. Longstreet would command Pickett's Virginia division of his own First Corps, plus six brigades from Hill's Corps, in an attack on

1134-403: A full-scale attack if a favorable opportunity presented itself. Lee's plan, however, was based on faulty intelligence, exacerbated by Stuart's continued absence from the battlefield. Though Lee personally reconnoitered his left during the morning, he did not visit Longstreet's position on the Confederate right. Even so, Lee rejected suggestions that Longstreet move beyond Meade's left and attack

1260-512: A grant that incorporated all lands included in the original Virginia Company of Plymouth Grant and other lands. This grant was in conflict with the Dutch claim for New Netherland , which included parts of today's Pennsylvania. On June 24, 1664, the Duke of York sold the portion of his large grant that included present-day New Jersey to John Berkeley and George Carteret for a proprietary colony. The land

1386-451: A heavy snowstorm, presumably because of a faulty flue . The General Assembly met at a nearby Methodist Church until a new capitol could be built. Following an architectural selection contest, Chicago architect Henry Ives Cobb was asked to design and build a replacement building. However, the legislature had little money to allocate to the project. When they dubbed the roughly finished, somewhat industrial Cobb Capitol building complete,

Healthcare, retail, transportation, and tourism are some of the state's growing industries of the postindustrial era. As in the rest of the nation, most residential population growth has occurred in suburban rather than central city areas, although both major cities have had significant revitalization in their downtown areas. Philadelphia anchors

1638-410: A minor engagement with newly promoted 23-year-old Brigadier General George Armstrong Custer 's Michigan cavalry near Hunterstown to the northeast of Gettysburg. Lee wished to renew the attack on Friday, July 3, using the same basic plan as the previous day: Longstreet would attack the Union left, while Ewell attacked Culp's Hill. However, before Longstreet was ready, Union XII Corps troops started

1764-415: A morale-boosting effect on the retreating Union soldiers, but he played no direct tactical role on the first day. General Lee understood the defensive potential to the Union if they held this high ground. He sent orders to Ewell that Cemetery Hill be taken "if practicable".

5292-630: The Carlisle and Harrisburg roads toward Gettysburg, while the Union XI Corps (Major General Oliver O. Howard ) raced north on the Baltimore Pike and Taneytown Road. By early afternoon, the Union line ran in a semicircle west, north, and northeast of Gettysburg. However, the Union did not have enough troops; Cutler, whose brigade was deployed north of the Chambersburg Pike, had his right flank in

5418-510: The Confederate line was nearly five miles (8 km) long. Lee's battle plan for July 2 called for a general assault of Meade's positions. On the right, Longstreet's First Corps was to position itself to attack the Union left flank, facing northeast astraddle the Emmitsburg Road, and to roll up the Union line. The attack sequence was to begin with Maj. Gens. John Bell Hood 's and Lafayette McLaws 's divisions, followed by Major General Richard H. Anderson 's division of Hill's Third Corps. On

5544-484: The Confederates could gain control of these heights, Meade's army would have difficulty dislodging them. Heth's division advanced with two brigades forward, commanded by brigadier generals James J. Archer and Joseph R. Davis . They proceeded easterly in columns along the Chambersburg Pike. Three mi (5 km) west of town, about 7:30 a.m. on July 1, the two brigades met light resistance from vedettes of Union cavalry, and deployed into line. According to lore,

5670-650: The Confederates had pushed the Union cavalrymen east to McPherson Ridge, when the vanguard of the I Corps (Major General John F. Reynolds ) finally arrived. North of the pike, Davis gained a temporary success against Brigadier General Lysander Cutler 's brigade but was repelled with heavy losses in an action around an unfinished railroad bed cut in the ridge. South of the pike, Archer's brigade assaulted through Herbst (also known as McPherson's) Woods. The Union Iron Brigade under Brigadier General Solomon Meredith enjoyed initial success against Archer, capturing several hundred men, including Archer himself. General Reynolds

On March 12, 1664, King Charles II of England gave James, Duke of York

5922-412: The Emmitsburg Road to south of the Codori farm. This created an untenable salient at the Peach Orchard; Brigadier General Andrew A. Humphreys 's division (in position along the Emmitsburg Road) and Major General David B. Birney 's division (to the south) were subject to attacks from two sides and were spread out over a longer front than their small corps could defend effectively. The Confederate artillery

6048-427: The General Assembly refused to occupy the building. In 1901, political and popular indignation prompted a second contest that was restricted to Pennsylvania architects; Joseph Miller Huston of Philadelphia was chosen to design the present Pennsylvania State Capitol that incorporated Cobb's building into a magnificent public work, finished and dedicated in 1907. James Buchanan , a Franklin County native, served as

6174-434: The I Corps division of Brigadier General John C. Robinson south of Oak Hill. Early's division profited from a blunder by Brigadier General Francis C. Barlow , when he advanced his XI Corps division to Blocher's Knoll (directly north of town and now known as Barlow's Knoll); this represented a salient in the corps line, susceptible to attack from multiple sides, and Early's troops overran Barlow's division, which constituted

6300-492: The II Corps, most of the XII Corps, and portions of the newly arrived VI Corps. Hood's division moved more to the east than intended, losing its alignment with the Emmitsburg Road, attacking Devil's Den and Little Round Top. McLaws, coming in on Hood's left, drove multiple attacks into the thinly stretched III Corps in the Wheatfield and overwhelmed them in Sherfy's Peach Orchard . McLaws's attack eventually reached Plum Run Valley (the "Valley of Death") before being beaten back by

6426-450: The Iron Brigade was pushed out of the woods toward Seminary Ridge. Hill added Major General William Dorsey Pender 's division to the assault, and the I Corps was driven back through the grounds of the Lutheran Seminary and Gettysburg streets. As the fighting to the west proceeded, two divisions of Ewell's Second Corps, marching west toward Cashtown in accordance with Lee's order for the army to concentrate in that vicinity, turned south on

6552-409: The Netherlands confirmed the English conquest on July 21, 1667, although there were temporary reversions. On September 12, 1672, during the Third Anglo-Dutch War , the Dutch reconquered New York Colony / New Amsterdam , establishing three County Courts, which went on to become original Counties in present-day Delaware and Pennsylvania. The one that later transferred to Pennsylvania was Upland. This

6678-536: The North and forcing his retreat. After his success at Chancellorsville in Virginia in May 1863, Lee led his Confederate forces through Shenandoah Valley to begin the Gettysburg Campaign , his second attempted invasion of the North. With Lee's army in high spirits, he intended to shift the focus of the summer campaign from war-ravaged Northern Virginia in the hopes of penetrating as far as Harrisburg, Pennsylvania or Philadelphia , which he hoped would convince northern politicians to abandon their prosecution of

6804-440: The North, leading to the Union's preservation . Throughout the late 19th and 20th centuries, the state's manufacturing-based economy contributed to the development of much of the nation's early infrastructure, including key bridges, skyscrapers , and military hardware used in U.S.-led victories in World War I , World War II , and the Cold War . Pennsylvania's geography is highly diverse. The Appalachian Mountains run through

6930-439: The Petun of New York, the Wyandot of Ohio, and the Tiontatecaga of the Kanawha River in southern West Virginia. South of the Allegheny River was a nation known as Calicua, which may have been part of the Monongahela culture . In the 17th century, the Dutch and the English each claimed both sides of the Delaware River as part of their colonial lands in America. The Dutch were the first to take possession. By June 3, 1631,

7056-447: The Potomac, initially under Hooker (Meade replaced Hooker in command on June 28), consisted of more than 100,000 men in the following organization: During the advance on Gettysburg, Reynolds was in operational command of the left, or advanced, wing of the Army, consisting of the I, III, and XI corps. Many other Union units (not part of the Army of the Potomac) were actively involved in the Gettysburg Campaign, but not directly involved in

7182-563: The Quakers and the Indians. Additional treaties between Quakers and other tribes followed. The Treaty of Shackamaxon of William Penn was never violated. Between 1730 and when the Pennsylvania Colony was shut down by Parliament with the Currency Act in 1764, the Pennsylvania Colony made its own paper money to account for the shortage of actual gold and silver. The paper money was called Colonial Scrip . The Colony issued bills of credit, which were as good as gold or silver coins because of their legal tender status. Since they were issued by

7308-413: The Union II Corps position at the right center of the Union line on Cemetery Ridge. Prior to the attack, all the artillery the Confederacy could bring to bear on the Union positions would bombard and weaken the enemy's line. Much has been made over the years of General Longstreet's objections to General Lee's plan. In his memoirs, Longstreet states that he told Lee that there were not enough men to assault

7434-427: The Union XI Corps positions on East Cemetery Hill. Once started, fighting was fierce: Colonel Andrew L. Harris of the Union 2nd Brigade, 1st Division, XI Corps came under a withering attack, losing half his men. Avery was wounded early on, but the Confederates reached the crest of the hill and entered the Union breastworks, capturing one or two batteries. Seeing he was not supported on his right, Hays withdrew. His right

7560-410: The Union attack. The inconclusive battle, the largest predominantly cavalry engagement of the war, proved for the first time that the Union horse soldier was equal to his Southern counterpart. By mid-June, the Army of Northern Virginia was poised to cross the Potomac River and enter Maryland . After defeating the Union garrisons at Winchester and Martinsburg , Ewell's Second Corps began crossing

7686-751: The Union flank, capturing the supply trains and effectively blocking Meade's escape route. Lee did not issue orders for the attack until 11:00 a.m. About noon, General Anderson's advancing troops were discovered by General Sickles's outpost guard and the Third Corps—upon which Longstreet's First Corps was to form—did not get into position until 1:00 pm. Hood and McLaws, after their long march, were not yet in position and did not launch their attacks until just after 4:00   p.m. and 5:00   p.m., respectively. As Longstreet's left division, under Major General Lafayette McLaws, advanced, they unexpectedly found Major General Daniel Sickles 's III Corps directly in their path. Sickles had been dissatisfied with

7812-456: The Union lines in his front. Major General Edward "Allegheny" Johnson 's division had contemplated an assault on Culp's Hill, but they were still a mile away and had Rock Creek to cross. The few possible crossings would make significant delays. Because of this, only three of Johnson's four brigades moved to the attack. Most of the hill's defenders, the Union XII Corps, had been sent to the left to defend against Longstreet's attacks, leaving only

7938-583: The Union soldier to fire the first shot of the battle was Lieutenant Marcellus Jones . Eventually Heth's men encountered dismounted troopers of Colonel William Gamble's cavalry brigade. The dismounted troopers resisted stoutly, delaying the Confederate advance with most firing their breech-loading Sharp's carbines from behind fences and trees. (A small number of troopers had other carbine models. A small minority of historians have written that some troopers had Spencer repeating carbines or Spencer repeating rifles but most sources disagree.) Still, by 10:20 am,

8064-511: The air. The leftmost division of the XI Corps was unable to deploy in time to strengthen the line, so Doubleday was forced to throw in reserve brigades to salvage his line. Around 2:00   p.m., the Confederate Second Corps divisions of major generals Robert E. Rodes and Jubal Early assaulted and out-flanked the Union I and XI corps' positions north and northwest of town. The Confederate brigades of Colonel Edward A. O'Neal and Brigadier General Alfred Iverson suffered severe losses assaulting

8190-465: The bloody Battle of Antietam ). Such a move would upset the Union 's plans for the summer campaigning season and possibly reduce the pressure on the besieged Confederate garrison at Vicksburg . The invasion would allow the Confederates to live off the bounty of the rich Northern farms while giving war-ravaged Virginia a much-needed rest. In addition, Lee's 72,000-man army could threaten Philadelphia, Baltimore , and Washington , and possibly strengthen

8316-475: The brigades of Pettigrew and Colonel John M. Brockenbrough . As Pettigrew's North Carolina Brigade came on line, they flanked the 19th Indiana and drove the Iron Brigade back. The 26th North Carolina (the largest regiment in the army, with 839 men) lost heavily, leaving the first day's fight with around 212 men. By the end of the three-day battle, they had about 152 men standing, the highest casualty percentage for one battle of any regiment, North or South. Slowly

While it has no ocean shoreline, it has 140 miles (225 km) of waterfront along Lake Erie and the tidal Delaware River. Pennsylvania is the fifth-most populous state in the United States , with over 13 million residents as of the 2020 United States census . The state

8568-429: The city's population as of 2000. In the 20th century, as Pennsylvania's historical national and even global leadership in mining largely ceased and its steelmaking and other heavy manufacturing sectors slowed, the state sought to grow its service and other industries to replace the jobs and economic productivity lost from the downturn of these industries. Pittsburgh's concentration of universities has enabled it to be

8694-591: The command of Major General J.E.B. Stuart . The Union Army of the Potomac under Major General Joseph Hooker consisted of seven infantry corps, a cavalry corps, and an artillery reserve, for a combined strength of more than 100,000 men. The first major action of the campaign took place on June 9 between cavalry forces at Brandy Station , near Culpeper, Virginia . The 9,500 Confederate cavalrymen under Stuart were surprised by Major General Alfred Pleasonton 's combined arms force of two cavalry divisions (8,000 troopers) and 3,000 infantry, but Stuart eventually repelled

8820-614: The crucial phase of the approach to Gettysburg and the first two days of battle. By June 29, Lee's army was strung out in an arc from Chambersburg (28 mi (45 km) northwest of Gettysburg) to Carlisle (30 mi (48 km) north of Gettysburg) to near Harrisburg and Wrightsville on the Susquehanna River . In a dispute over the use of the forces defending the Harpers Ferry garrison, Hooker offered his resignation, and Abraham Lincoln and General-in-Chief Henry W. Halleck , who were looking for an excuse to rid themselves of him, immediately accepted. They replaced Hooker early on

8946-420: The development of labor unions helped them gain living wages. However, the rise of unions also led to a rise of union busting with several private police forces springing up.

Penn established a government with two innovations,

10206-623: The largest chocolate manufacturer in North America. Heinz Company was also founded during this period. These huge companies exercised a large influence on the politics of Pennsylvania; as Henry Demarest Lloyd put it, oil baron John D. Rockefeller "had done everything with the Pennsylvania legislature except refine it".

On June 30, while part of Hill's corps was in Cashtown, one of Hill's brigades (North Carolinians under Brigadier General J. Johnston Pettigrew ) ventured toward Gettysburg. In his memoirs, Major General Henry Heth , Pettigrew's division commander, claimed that he sent Pettigrew to search for supplies in town—especially shoes. When Pettigrew's troops approached Gettysburg on June 30, they noticed Union cavalry under Major General John Buford arriving south of town, and Pettigrew returned to Cashtown without engaging them. When Pettigrew told Hill and Heth what he had seen, neither general believed that there

The Confederate line paralleled the Union line about one mile (1,600 m) to the west on Seminary Ridge, ran east through the town, then curved southeast to a point opposite Culp's Hill. Thus, the Union army had interior lines, while

11214-403: The northwest of Gettysburg were initially defended by a Union cavalry division under Brigadier General John Buford , and soon reinforced with two corps of Union infantry . Two large Confederate corps assaulted them from the northwest and north, however, collapsing the hastily developed Union lines, leading them to retreat through the streets of Gettysburg to the hills just south of the city.
