Editing First Belt Ice-Hauler Convoy (section)

=== Boarding attempt and repulse ===

The boarding of Callisto-4 by four Syndicate personnel was the most kinetically dangerous episode of the confrontation. The Syndicate boarding skiff had docked at the hauler's secondary lock before the Meridian could physically interpose. Sable Idris, acting on orders from Petra Volkov, brought the Meridian alongside Callisto-4 at close range and inserted a four-person detachment through the primary lock.

In the confined forward corridor of Callisto-4, the Shackleton crew and Idris's detail confronted the Syndicate personnel. One Syndicate crew member — later identified in Cooperative records as Enforcement Agent Biro Pask — was killed in the ensuing struggle. The remaining three surrendered and were held aboard Callisto-4 for the duration of the transit. Two Shackleton crew members suffered injuries from pressurisation disruption during the lock breach.
