As per the World War I Diary authored by Jose de la Luz Saenz (and translated by Emilio Zamora [see previous post]), the town was obliterated by the Germans with 12 large projectiles.
After this, a 150-millimeter cannon began to bomb Luz and his fellow soldiers with him writing his concluding thought that day,
Without a doubt, Luz was an extraordinary person. He voluntarily joined the military in order to be able to return home and make the case for civil rights for Mexican Americans, having paid with others the ultimate price of wartime sacrifice on behalf of the homeland.
It was a horrible day for the soldiers. The shells were flying over our heads, howling like souls from hell. (p. 195)
