First, the 25th amendment was ratified on February 10, 1967 and it's the one our lunatic left keeps bellowing at President Trump, right after "impeach 45".
So obviously, you meant to post, "13th amendment", which did abolish slavery, on December 6, 1865.
Second, Grant's family was anti-slavery and Grant owned no slaves, but Grant's wife Julia (Dent) was a wealthy Southerner and her family did own, many.
When Grant managed their farm, he managed their slaves.
In 1858 Grant's father-in-law gave Grant a slave, William Jones, said to be worth $1,500 at a time when Grant was near bankrupt.
Grant gave the slave his freedom in early 1859.
It has been said that Julia (Dent) Grant kept personal servants during the Civil War up until the time of Lincoln's emancipation in mid-1862 and the comment above may have been hers.
Btw, Julia Dent was a cousin to CSA Gen. Longstreet.
NKP_Vet: "The Union Army was given instructions that the first Confederate soldiers to be shot were black soldiers fighting alongside whites, of which there were many.
Yankee history books ignore this well-established fact."
Nonsense, that's just Democrats doing what Democrats do -- look deep in their own souls and accuse Republicans of whatever evils they find there.
In fact it was Confederates who refused to take Union colored troops prisoners -- one thing that made Union black soldiers such fierce fighters.
The truth about Confederate black soldiers is that, except for the occasional body servants standing along side their masters to reload rifles, there were none.
There were, of course, many tens of thousands of slaves supporting Confederate armies in every way possible except as fighting soldiers.
The Federal Army was segregated. On top of that black soldiers were in a support role until the war was half over.. The Confederate Army was never segregated. You are wrong in your assertion that black Confederate soldiers were not fighting and its easily disproven. Here’s an interesting article from a black man who went to war and fought with his owner. And guess what, he said he would do it again. They also were given discharges like any other soldier and applied and were given pensions like any other soldier.

The truth is until very recently Southern persons of color knew they had Confederate ancestors, and they knew the truth of Lincoln’s illegal war because their ancestors told them.
Here is an example of black Mississippi legislator, John F Harris, making a speech in favor of the erection of a Confederate monument in 1890 who came to address the legislature from a sick bed when he found out a member had opposed the monument.
Give this a read and you’ll understand why the Sons and Daughters of Confederates should never have decided to become ghosts in society.
“Mr. Speaker! I have arisen here in my place to offer a few words on the bill. I have come from a sick bed ... perhaps it was not prudent for me to come. But, sir, I could not rest quietly in my room without ... contributing ... a few remarks of my own. I was sorry to hear the speech of the young gentleman from Marshall County. I am sorry that any son of a Soldier should go on record as opposed to the erection of a monument in honor of the brave dead. And, Sir, I am convinced that had he seen what I saw at Seven Pines and in the Seven Days’ fighting around Richmond, the Battlefield was covered with the mangled forms of those who fought for their country and for their countries honor, he would not have made that speech.
When the news came that the South had been invaded, those men went forth to fight for what they believed, and they made no requests for monuments. ... But they died, and their virtues should be remembered. Sir, I went with them. I too, wore the gray, the same color my master wore. We stayed four long years, and if that war had gone on till now I would have been there yet ... I want to honor those brave men who died for their convictions. When my mother died I was a boy. Who, Sir, then acted the part of a mother to the orphaned slave boy, but my ‘old missus’? Were she living now, or could speak to me from those high realms where are gathered the sainted dead, she would tell me to vote for this bill. And, Sir, I shall vote for it. I want it to be known to all the world that my vote is given in favor of the bill to erect a monument in honor of the Confederate dead.”
