Content:  The name "BULLRUN" was taken from the First Battle of Bull Run, the first major battle of the American Civil War.

Title: Turning point of the American Civil War
Content:  The First Battle of Bull Run, on July 21, 1861, was the first major land battle of the war. Until this time, the North was generally confident about its prospects for quickly crushing the rebellion with an easy, direct strike against the Confederate capital at Richmond, Virginia. The embarrassing rout of Brig. Gen. Irvin McDowell's army during the battle made clear the fallacy of this viewpoint. Many Northerners were shocked and realized that the war was going to be much lengthier and bloodier than they had anticipated. It steeled their determination. If Confederates had hoped before this that they could sap Northern willpower and quietly slip away from the Union with 
Title: Second Battle of Bull Run
Content:   The Second Battle of Bull Run began on August 28 as a Federal column, under Jackson's observation just outside Gainesville, near the farm of the John Brawner family, moved along the Warrenton Turnpike. It consisted of units from Brig. Gen. Rufus King's division: the brigades of Brig. Gens. John P. Hatch, John Gibbon, Abner Doubleday, and Marsena R. Patrick, marching eastward to concentrate with the rest of Pope's army at Centreville. King was not with his division because he had suffered a serious epileptic attack earlier that day. Jackson, who had been relieved to hear earlier that Longstreet's men were on their way to 
Title: First Battle of Bull Run
Content:  The First Battle of Bull Run (the name used by Union forces), also known as the Battle of First Manassas (the name used by Confederate forces), was the first major battle of the American Civil War. The battle was fought on July 21, 1861, in Prince William County, Virginia, just north of the city of Manassas and about 30 miles west-southwest of Washington, D.C. The Union's forces were slow in positioning themselves, allowing Confederate reinforcements time to arrive by rail. Each side had about 18,000 poorly trained and poorly led troops in their first battle. It was a Confederate victory, 
Title: First Battle of Bull Run
Content:  by a disorganized retreat of the Union forces. Just months after the start of the war at Fort Sumter, the Northern public clamored for a march against the Confederate capital of Richmond, Virginia, which was expected to bring an early end to the Confederacy. Yielding to political pressure, Brig. Gen. Irvin McDowell led his unseasoned Union Army across Bull Run against the equally inexperienced Confederate Army of Brig. Gen. P. G. T. Beauregard camped near Manassas Junction. McDowell's ambitious plan for a surprise flank attack on the Confederate left was poorly executed; nevertheless, the Confederates, who had been planning to 
Title: First Battle of Bull Run
Content:  On the morning of July 21, McDowell sent the divisions of Hunter and Heintzelman (about 12,000 men) from Centreville at 2:30 a.m., marching southwest on the Warrenton Turnpike and then turning northwest toward Sudley Springs to get around the Confederates' left. Tyler's division (about 8,000) marched directly toward the Stone Bridge. The inexperienced units immediately developed logistical problems. Tyler's division blocked the advance of the main flanking column on the turnpike. The later units found the approach roads to Sudley Springs were inadequate, little more than a cart path in some places, and did not begin fording Bull Run until 9:30 a.m. Tyler's men reached the Stone Bridge around 6 
Title: Second Battle of Bull Run
Content:  Cavalry headed for Lewis Ford, a crossing in Bull Run Creek that would enable them to get in the rear of the Union army. However, Robertson and Rosser found the crossing blocked by John Buford's cavalry and after a short, but fierce engagement, Buford's superior numbers won out and the Confederate horsemen pulled back. The cavalry clash lasted only about ten minutes, but resulted in Col. Thomas Munford of the 2nd Virginia Cavalry being wounded. Col. Thornton Brodhead of the 1st Michigan Cavalry was shot dead, and John Buford was also wounded. The Union army's retreat however had been safeguarded.
Title: Bull Run (Occoquan River tributary)
Content:  Bull Run is a 32.8 mi tributary of the Occoquan River that originates from a spring in the Bull Run Mountains in Loudoun County, Virginia, and flows south to the Occoquan River. Bull Run serves as the boundary between Loudoun County and Prince William County, and between Fairfax County and Prince William County. Bull Run is primarily associated with two battles of the American Civil War: the First Battle of Bull Run (July 21, 1861) and the Second Battle of Bull Run (August 28–30, 1862), both Confederate victories. A narrow part of the creek called Yates Ford (near Manassas) is the scene of the Battle of Occoquan, and downstream about one mile is the current Yates Ford Road bridge between Fairfax and Prince William counties.
Title: Bull Run, Oregon
Content:  Bull Run is an unincorporated community in Clackamas County, Oregon, United States. It is located about 5 miles northeast of Sandy, near the Bull Run River and the powerhouse of the defunct Mount Hood Railway and Power Company (later the Bull Run Hydroelectric Project). George H. Himes believed the name "Bull Run" may have been because of the presence of wild cattle along the river in the pioneer era of 1849–55. This story is corroborated by settler Charles B. Talbot, who said that cattle would escape from the early immigrants to the area and ran wild for several years, and 
Title: Second Battle of Bull Run
Content:   The Second Battle of Bull Run or Battle of Second Manassas was fought August 29–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run (or First Manassas) fought on July 21, 1861 on the same ground. Following a wide-ranging flanking march, Confederate Maj. Gen. Thomas J. "Stonewall" Jackson captured the Union supply depot at Manassas Junction, threatening Pope's line of communications with Washington, D.C. Withdrawing a few
