ah, in Catilinam . . . You’ve come far with the piece in question: let me try to help with the last bits.
very good
desiderant is third person pl., so I assume castra is the subject, but the subject may be implied and castra is an object.
stick to your first assumption: castra desiderant
Is tua paired with castra or Manliana or is illa paired with Maliana or castra?
actually, tua, Manliana and illa all go with castra - one could translate it thus: that ‘Manlian’ camp of yours
If this is an indirect statement, where is the infinitive or is it implied? Be it implied, I have no clue what C is talking about.
oh, I think you are looking for an ACI, are you? Try this instead. The camp wants the direct object: te. Then try inserting a little ‘as’ (it’s a predicative accusative): I think you’ll get it to make sense then
