How did Johnson move his troops to manassas?

General Joseph E. Johnston moved his Confederate troops to Manassas by utilizing a combination of railroads and marching. He coordinated the movement of his forces from various locations, notably from the Shenandoah Valley, using the Virginia Central Railroad to transport troops efficiently. This logistical strategy allowed him to concentrate his forces quickly in preparation for the First Battle of Bull Run, which took place in July 1861. Johnston's swift movement was crucial in bolstering the Confederate defenses in the region.
