The earth-minbari war started in 2245 when an earth exploration fleet led by EAS (earth alliance ship) Prometheus captained by Michael Jankowski went off mission to scan and get a good look at the then elusive minbari, while scanning the minbari, the grey council fleet (minbari fleet being scanned by humans) picked them up on the scanners, the warriors caste sent the lead ship of the fleet with the grey council onboard to greet them, the warrior caste made the cruiser open its gun ports as a sign that they would not fire, the EAS prometheus crew became spooked when this happened, this coupled with the steath technology that jammed the humans deep scans ended up with the capptain Michael Jankowski to order all ships (the prometheus, one earth ddestroyers, 2 bombers and a bnumber of star fruy fighter) to open fire, the attack surprised the Minbari and heavily damaged the minbari cruiser, killing around a quarter of the crew including the leader of the grey council thiis led five of the nine members of the grey council to follow the humanbs and exterminate them.

The minbari began a genocidal campaign against humanity, destroying base after base, although encounting heavy human restistance the minbari lost little to no ships and continued to slaugther humanity, the first major victory came when Vice-Captain John Sheridan onboard the badly damaged EAS Lexington hatched a plan up putting nuclear mines onb asteroids and lured in the Minbari flagship the black star, it is lured in and destroyed by the mines, this marked the first human victory in the war, being only one of two, the second was when an Unkown earth destroyer went up against a minbari cruiser, with the weapons destoryed and life support crippled the rammed the minbari cruiser, destorying both ships.

The battle of the line was the final battle in the earth-minbari war,
