"Emden" was the first to fire at 09:40, and scored hits on her fourth salvo: two shells exploded near the aft control station and wrecked the aft rangefinders, while a third punched through the forward rangefinder and through the bridge without exploding. These shots landed at a range of approximately ; the 30-degree elevation of her main guns allowed her to fire much further than British estimates. Von Müller recognised that his success in the battle required "Emden" to do as much damage as possible before the other ship retaliated, but despite the heavy rate of fire from the Germans over the next ten minutes (at points reaching a salvo every six seconds), the high angle of the guns and the narrow profile presented by "Sydney" meant that only fifteen shells hit the Australian warship, of which only five exploded. As well as the rangefinders, damage was sustained to the S2 gun when a nearby impact sent hot shrapnel into the gun crew then ignited cordite charges being stored nearby for the fight, and another shell exploded in a forward mess deck. Four sailors were killed and another sixteen wounded; the only casualties aboard "Sydney" during the entire engagement.
