In grep, you use parentheses to capture strings for later use.  $n  
returns whatever string was captured by the nth set of parens.  Thus,  
$1 should return whatever is captured by the first set of parentheses.

I can't see why it wouldn't work for something beginning with a  
number, but mod_rewrite is pretty much voodoo -- a lot of trial and  

Try misterhaan's version and see if that does better:

RewriteRule ^[0-9]{4}(/[0-9]{2}){2}/([^/]+)/?$ /articles/$2/ [R=301,L]

Otherwise, try experimenting.  My best guess is that somehow the  
number beginning the article name was tripping the [0-9] part of the  
RegEx, but I'm not sure how, since we should have been past that
