Here are some hints about searching online. In order to get the above results, I went to www.google.com and entered this, including the quotation marks --
"March 10, 1935" Hitler violate "treaty of Versailles"
The quotation marks are around the parts of the search terms that I want the search engine to keep together. Otherwise I'd end up with other stuff about Hitler or Versailles or 1935 or whatever.
