Trafalgar is described as surviving one plasma-beam hit before taking another, while its heavy guns destroy Covenant ships. That endurance gives the Epsilon Eridani fleet more time to fight against much stronger opposition. Its achievement is interpreted as a delaying action that enables Pillar of Autumn and Master Chief to survive. A follow-up argues that more Punic-class ships earlier would have put the UNSC in a stronger position. That last claim is a counterfactual within Halo's fictional history.
