You may be asking yourself, “Why was this order necessary?” After all, the Emancipation Proclamation that declared “all persons held as slaves are, and henceforward shall be free” was issued more than two years before on January 1, 1863. The United States Congress had also already passed the 13th Amendment to end slavery nearly 6 months before on January 31, 1865. And General Robert E. Lee had already surrendered to General Ulysses S. Grant on April 9, 1865, marking the end of the Civil War.
There are a few reasons:
1. The Emancipation Proclamation didn’t free all enslaved people at the time it was issued;
2. The United States had no means to enforce the 13th Amendment; and
3. Because of Texas’ remote location, slave owners were able to maintain and enforce slavery after Lee’s surrender due to the minimal number of Union troops available to enforce emancipation.
