Este pode ser o de Richard C. Meredith <> (1969), como referenciado em esta resposta inaceitável anterior a uma pergunta sobre um romance com uma premissa similar. Os alienígenas inimigos são chamados de "Jillies", como visto na citação de uma resenha na resposta:
Now the Jillies are massing to attack Breakaway Station. This station is only lightly defended and unless reinforcements can be delivered in time, the Jillies will take it.
Earth however has no regular forces close enough to protect the station. The only possible reinforcement is a hospital ship and the two battle cruisers escorting it back to Earth. The hospital ship carries the frozen remains of thousands of solders who may still be revived and repaired. The crews of the ships are war casualties themselves, still desperately injured, temporarily repaired, some rebuilt as cyborgs.
