From the description of this video: 

"Confederate soldier Julius Howell talking about his capture and imprisonment at the Union prison camp at Point Lookout, Md. Howell was born in 1846 near the Holy Neck section of Suffolk, in the Holland area. He was the youngest of 16 children, the son of a prominent Baptist minister. His daddy wouldn't allow him to join the army until he was 16½, he says in his account. 
He saw action guarding the Blackwater River against Yankees until his regiment was called to help defend Richmond in 1864. By then, he was a corporal and courier for two generals. 

In April 1865, Howell was taken prisoner at the battle of Sailor's Creek and was transported to Point Lookout, Md., a notorious Union prison. He was there when he heard about the assassination of President Abraham Lincoln. 

"I arose pretty early," he says. "There were 20,000 of us there. I saw a flag pole, and a flag stopped halfway." 

The youth, a slightly built man with bright red hair, knew what it meant. 

"I stuck my head in a tent and said, 'Boys, there must be some big Yankee dead.' " 

A guard told the men later that the president had been shot. Howell says he felt no hatred toward Lincoln, only kindness. 

"We didn't fight for the preservation or extension of slavery," he says. "It was a great curse on this country that we had slavery. We fought for states' rights, for states' rights." 

After the war, Howell taught at Reynoldson Institute in Gates County, N.C. He soon left teaching and went to the University of Pennsylvania, graduating with a history degree. From there, he went on to Harvard and got a doctorate in history. 

Howell was a history professor at the University of Arkansas. He eventually headed the department. In 1901, he was named president of Virginia Intermont College in Bristol, where he served for 50 years. 

Howell was forever loyal to the South. He became state commander of the Tennessee Confederate Veterans and, in 1940, was named commander-in-chief of the national United Confederate Veterans. 

In 1942, Life magazine did a spread on Howell. Several photos of the old gentleman show him dressed in his Confederate uniform. Because legislators wanted to hear more from the Confederate veteran, Howell addressed the combined Congress of the United States in Washington in 1944, when he was 98, and that is when it is believed this tape was made. 

Four years later, in February 1948, on his 102nd birthday, the city of Bristol threw a party. His old friend, actress Mary Pickford, and her family attended. 

Howell, who had never been sick a day in his life, died the following June. 

Julius Howell was the great-great-uncle of former ANV Commander Russell Darden. 

All credit goes to sons of confederate veterans i dont take any credit for this, http://www.scv.org/JuliusHowell.php 

let us be  in peace.....
God Bless Dixie and all brave confederate soldiers."

Just in case YouTube takes down this historical recording, I've attached a download of this file below. 

A good recording by Julius Howell. 

He refers to the Union soldiers as 'federal' soldiers, which I have not heard of before. I guess that term makes sense. It sounds like there's more to the recording, as it seems to end abruptly. I'd like to hear the rest of it. 

IMO, there should not have been a war between the states, or rather, between the federal gov. and the southern states. Slavery would have ended eventually, and likely wouldn't have lasted much longer anyway. There was too much loss of life on both sides of the war. If the South wished to secede, they should have been allowed to do so, though it seems kind of drastic. 

… Howell addressed the combined Congress of the United States in Washington in 1944, … and that is when it is believed this tape was made.

Anachronism alert! The highlighted words should be "this recording" rather than what they are.

Any audio recordings made in the United States before late 1946 were made either on wax-coated metal discs or on the kind of film stock developed in the 1930s for use in the motion picture industry. German engineers at what became the Magnetophon company invented magnetic recording tape and tape recorders in the 1930s, but no other country in the world had access to this breakthrough technology until it was stolen liberated by a US Army Signal Corps technician named Jack Mullin after the destruction of Germany at the end of World War II.*

In 1944 the US Congress was making audio recordings on what were called transcription discs: sixteen-inch low-fidelity wax-covered discs, the same medium that radio stations used to record big-band performances intended for later broadcast. Rare congressional video recordings were made with standard Hollywood film stock, usually 16 mm.

*Mullin sold the equipment he brought home with him to the Ampex company, which was owned by a Russian-born communist Jєω, Alexander M. Poniatoff. Ampex then marketed the German Magnetophon tape recorders as its own invention. A dishonest Jєω—whoever heard of such a thing!

He refers to the Union soldiers as 'federal' soldiers, which I have not heard of before. I guess that term makes sense.

This was the term that Confederate officers and official communiques routinely used to refer to members of the US armed forces. Soldiers on both sides had numerous impolite and insulting terms for their antagonists, but in the circuмstances in question, such language would hardly have been appropriate. Howell was a gentleman, after all, not a murderous BLM degenerate.
