One Killmail, Seven Pilots, No Second Loss
There is no fleet list here to argue over. The record contains a single destroyed ship, no capital losses, no structure losses and no capsule noted alongside it. GraveDiggers appears as the attacking organisation; Goonswarm Federation appears as the victim's. Seven pilots are named in the killmail, which is enough to establish that the Marshal did not simply evaporate - but not enough to say anything about how the engagement was set up, how long it lasted, or whether anything else burned that day.
Expensive Metal in Wicked Creek
The 12.6B ISK figure is an individual loss value, not a fleet total carved up between wrecks. For a single non-capital hull, that is a hefty price to have removed from the region, and it lands squarely on Cobalt Spirit's ledger. No top damage contributor is supplied, so credit for the work stops where the evidence does - at the final blow held by Dark xKnightx. Beyond that, the record offers one clean fact: in UY5A-D, a Marshal was flying under Goonswarm colours, and it is not flying anymore.
