Star Trek: Battle of Wolf 359

We are the Borg. Existence, as you know it, is over. We will add your biological and technological distinctiveness to our own. Resistance is futile.

The Battle of Wolf 359.  40 Starfleet ships and a large number of Klingon battle cruisers versus a single Borg Cube.  It took place.  We could hear the screams of the people on those ships dying.  By the time Enterprise arrived, it was over.  Worse, Captain Jean Luc Picard made it possible when he was assimilated and turned into Locutus.

Our only glimpse of the actual battle comes in the opening moments of the spin-off show, Deep Space Nine.  We watch as the U.S.S. Saratoga is destroyed in the battle.  Benjamin Sisko barely escapes with his son, but has to leave his wife behind.

Probably one of the most intense space battles of the time, made more so by the fact that the crew of the Enterprise couldn’t do anything about it.  Add to that the fallout it created with all the people who lost loved ones and blamed Picard and you have one of the best space battles.
