The Battle of Orchard Knob, a rocky hill to the east of Chattanooga was fought November 23rd 1863.
Union General George H Thomas formed his troops up in the valley between Chattanooga, Tennessee and rocky hill about 100 feet high, known as Orchard Knob on the afternoon of November 23rd 1863. Confederates posted on top of Orchard Knob watched the Union troops from behind rifle pits, as they move as though on parade in front of their position.
Somewhere around 1:30 pm the 14,000 Union soldiers began to march on the Confederate position at the double quick. There were only 634 Confederates holding the line on Orchard Knob. The Confederate soldiers had time only to fire a single volley before Thomas’ troops closed in on the Knob, pushing the Confederates back to the base of Missionary Ridge. By 3 pm Union General Thomas J Wood was sending the message to Thomas, that "I have taken the first line of the enemy's entrenchments." Thomas sent back the order, “Hold on; don't come back; you have got too much; entrench your position."
Union General Ulysses S Grant would use Orchard Knob on November 25th 1863 as his forward observation point, while watching the Union assault on Missionary Ridge.
