During the landing at Anzac Cove during the Battle of Gallipoli on 25 April, "Bacchante" suppressed Turkish artillery positions at Gaba Tepe after touching her bow the beach for a better position from which to engage the guns. She provided fire support for forces near Anzac Cove for the next several months, particularly during the Third attack on Anzac Cove on 19 May when she, together with three pre-dreadnought battleships, effectively suppressed the Turkish artillery assigned to support the attack. On 28 May "Bacchante" and the destroyer destroyed enemy shipping in Budrum harbour. Three months later the cruiser bombarded Turkish troops during the Battle of Lone Pine on 6 August and Battle of Chunuk Bair 7–9 August. She was not present when the Allies began to evacuate Gallipoli in December, but her captain, Algernon Boyle, commanded the evacuation at Anzac Cove.
