In 2370, the Cardassian warship Vetar came under attack by a fleet of small Maquis attack fighters armed with photon torpedoes and type 8 phasers, which inflicted heavy damage to the Vetar. Gul Evek accused the Federation of supplying these supposed civilians with the weaponry, but Captain Jean-Luc Picard assured Evek that however they got them, it was through unofficial channels.
