dno
in a newspaper hehehehehe
Although I was unable to find a definite answer after reading the article on the battle, there were a few references to mustard gas (Sulfur Mustard), so that would be my guess.
if they are in the newspaper, usualy you look in the first section if you cant find them look through out the book.
You're going to have to find the article online but you can still cite the work.
Can you find a newspaper or magazine article that involves a statistical study on the internet?
on the internet just type in "a newspaper about the superbowl" then the newspaper will come up if you click on the right site.
you need to get out there and see the goings ons
Often times historical newspaper articles can be found in libraries or in online memorabilia/collector stores.
One can find a newspaper article that describes an action carried out by one branch of the federal government. Two good newspapers to find these type of articles are The Washington Times and The Washington Post.
Sift through all the minutia to find a tidbit worthy of a newspaper article.
Check with a large city's library, or that newspaper's archives, if the newspaper is still in business. (This may be harder if you don't live in England.)
I'm not quite sure if you are looking for general info or info of your grandfather but if you go to google.com and type in Battle of the Somme there is ample info available that may lead you to what you are looking for! There are too many links to add them to this question.
