About Union forces in Laredo, there was a base called Ft. McIntosh which hosted the 2nd Cavalry. They were stretched very thin as most soldiers were on the frontier. [url]https://en.wikipedia.org/wiki/Fort_McIntosh,_Texas[/url] [url]http://www.texasbeyondhistory.net/forts/military.html[/url]

Just an FYI, I don't care if we ignore their presence or have there fighting unit out patrolling during this time of the raid.
