As Anaris said, open the battle report itself from the scribe note link, and save the entire page. (Usually CTRL-S.) Once you have that, you have a copy of the HTML that you can use elsewhere. Someone once figured out how you could convert the HTML to wiki-code, or how to clean up the HTML to work on the wiki. The procedure is on the wiki somewhere. It's a lot of work, as the battle report formatting depends on the standard battlemaster CSS which is not available on the wiki.
You cannot just copy/paste the text you seen in your browser. You will end up with an illegible mess.
