A game of base ball came off yesterday morning on the Laclede Ball Grounds, between the Commercial, Jr., and the Baltic Base Ball Clubs, which resulted in favor of the former.

Five days before this game was played, the Siege of Vicksburg began and Edward Bredell, co-founder of the Cyclone Club, was there, serving as aide-de-camp to Confederate General John Bowen. Also there, serving as aide-de-camp to Union General U.S. Grant, was Bredell's former club-mate, John Riggin. I have no idea if either of the two men was aware that the other was there.
