Opening of the Base Ball Season. - The Empire Club observed their fifth anniversary yesterday by a match between the married and single members. There was a large assemblage of ladies and gentlemen on the ground, who were received with that kindly hospitality so characteristic of the Empire boys. The married members, under the sagacious lead of Captain Fruin, obtained a single victory over their bachelor brothers, who under the lead of Captain Wirth, struggled hard to carry off the prize. The runs stood: married 25; single 11. The marked features of the game were an ace by J.T. Murphy, of the bachelors, and five runs made by H. Noble, of the benedicts.

The other thing I wanted to point out was the use of the term "ace" to denote a home run. I've seen it before in the early records of the game in St. Louis but it is fairly unique. If I remember correctly, it was a cricket term that got carried over to baseball.
However, Abraham Lincoln was assassinated on April 14, 1865, and his funeral procession in Washington D.C. was scheduled for April 19th. The Empire Club's anniversary game was overcome by events and it appears that the game on the 19th was cancelled in order to observe a period of mourning for the fallen President. The game was rescheduled and played on April 26, 1865.
This brings up the question of whether of not the Empire Club's fifth anniversary game was technically played during the Civil War. Lee had surrendered on April 9 but Joe Johnston didn't surrender the Army of Tennessee until April 26. There were still Confederate forces surrendering in June and the final surrender of a Confederate force didn't take place until November. Generally, I always believed it was Johnston's surrender that marked the end of the war and I'm willing to argue that this game took place on the final day of the Civil War.
Of course, one of the reasons I'm willing to make that argument is that I like the symmetry of St. Louis Civil War baseball beginning with a game three days after the fall of Fort Sumter and ending with a game on the war's final day. It's just about perfect.
