Ok..I just noticed my last post...it was nearly unreadable (possibly completely)... a combo of bad typing skills and multi tasking combined to make me illiterate! Sorry
I found out the answers to the Hewiett/Cook affair.
James Marmion was trying to help the widow of the young private Hewiett, she apparently had no means to support herself. Cook was an attorney..there are any number of resons James would have written an attorney in San Antonio.
All in all the whole point was that as he said he was being persecuted. James was from other accounts rather particular...could have been a type A, over achiver and this could have angered some of the men at Ringgold...and as Bob Marmion said, they saw no action, so boredom set in. Whatever may have been the trouble, and there was lots of it, it was gone when James became a Marine and wound up commanding the Matagorda Marine district.
