My absolutely favorite story of the ACW. Jealous you have the painting.

Sorry. TL;DR. Texas troops save the day.

Dawn. May 6,1864. General WS Hancock's II Corps launches an assault on General AP Hills Corps who neglected to entrench during the night. Confederate Infantry is driven back and begins to flee. A single battalion of Confederate Artillery and Generals Lee, Hill and their staffs are the only Confederates troops maintaining cohesion. As the gunners try to slow down the Federal Infantry a column of Confederate Infantry comes onto the field at the double quick and begins to form into a line of battle. General Lee not recognizing the brigade commander asks "General, what troops are these". General John Gregg, new to the Army of Northern Virginia responds, "General these are Texas troops". The only Texas troops in the Army of Northern Virginia are the 1st, 4th and 5th Texas as well as the 3rd Arkansas (known affectionately within the brigade as the 3rd Texas) and they belong to General James Longstreets Corps, who had been marching since 3am and at the double quick for the last 2 miles. General Lee responds that General Gregg must attack immediately as those people (Federals) will stand there all day unless you give them the bayonet. General Gregg commands the brigade "Attention Brigade. The eyes of General Lee are upon you. Forward March." Lee responds with "Texans always MOVE them". The men of the brigade with in ear shot begin to cheer and as the words travel down the line the cheer grows. Lee, uncharacteristically caught up in the emotion of the moment, rides to the front as of to lead the charge, which was tantamount to suicide as approximately 800men were advancing into 10,000. As the legend states the brigade halts their advance even as men are beginning to be shot down and refuse to move forward proclaiming "Go back General Lee, go back. We won't go for award until you go back". Other men begin to chant and yell "Lee to the rear". With (supposedly PVT Leonard Groce Gee) a soldier clutching the reins of Traveller, Lee is led behind the lines and the brigade continues their advance. Just under 600 men would fall, killed wounded and missing but their advance bought time to stabilize the line.

After the battle a simple marker was placed upon the mass grave of the brigade. It was simply a wooden plank nailed to a tree with the word "Texas Dead" written on it.

I think the quote is "Texans always MOVE them".

Damn. Didn't even realize that. Ha ha ha

Corrected now.
