GDG- Buford to Reynolds, July 1?

[Tom Ryan]

I do not find a message in Part 1 or Part 3 of OR, 27 from Buford to
Reynolds that he was under attack on July 1.  Also, in his report of the
battle, Buford makes no reference to having actually sent a message to
Reynolds on the morning of July 1.  Coddington also does not mention that
Buford alerted Reynolds to the attack.

I have no doubt that he did notify Reynolds on July 1, but cannot find a
rererence to it.  Does anyone know how Buford got the word to Reynolds he
was under attack?
