One day, the junkers were raiding a undefended convoy.
The miners tried to defend while the cargo ships were leaving, but were easily crushed.
One managed to send out a distress signal though, and a few minutes later...
A small fleet from the I.R.V. arrived. they engaged.
It was a rather easy victory. here are some more images:
All the cargo ships and miners were destroyed, but so were all the Junkers.
