The recent three-part documentary on the American Experience on PBS was surprisingly good. It even explored Woodrow Wilson's racial bigotry and how he tyrannically threw people in jail for daring to express disagreement with him.
My grandfather was gassed on or about Nov. 11, 1918, near Mont-devant-Sassy. My husband had distant cousins who earned their U.S. citizenship by serving during WWI. Both were wounded.
You never know what you'll get with PBS - I like it when I'm pleasantly surprised. They had an excellent series on WWII that focused on the weapons used, but also provided tons and tons of back story as well. Personally, I enjoy learning all the little details.
My grandfather was gassed as well but got lucky in that the damage was only minor. Still a big deal sure, but everything is relative and compared to the thousands of others he considered himself lucky. He worked with horses quite a bit and doing so beat him up more than the gas.
