line', but Tigers captain, believing that Indomitable was already engaging Blücher, fired at , as did Lion, which left unengaged and able to continue to engage Lion without risk. However, Lion scored the first serious hit of the battle when one of her shells penetrated the working chamber of Seydlitzs rear barbette at 09:40 and ignited the propellant lying exposed. The resulting fire spread into the other turret and burnt out both of them, killing 159 men. Seydlitz returned the damage at 10:01 with a shell that ricocheted off the water and pierced Lions five-inch armour aft, although it failed to explode. However, the resulting hole flooded the low power switchboard compartment and eventually shorted out two of Lions three dynamos. scored the most telling hits on Lion at 10:18 when two shells struck her port side below the waterline. The shock was so great that her captain, Ernle Chatfield, thought that she had been torpedoed. One shell pierced the five-inch armour forward and burst in a wing compartment behind the armour. It drove in a piece of armour and flooded several compartments adjacent to the torpedo flat and the torpedo body room. One splinter put a hole in the exhaust pipe of the capstan engine which eventually contaminated the auxiliary condenser with saltwater. The other shell hit further aft and burst on the six-inch portion of the waterline belt. It drove in two armour plates about and flooded some of the lower coal bunkers. At 10:41 a 283 mm shell burst against the eight-inch armour of 'A' barbette, but only started a small fire in the 'A' turret lobby that was quickly put out, although the magazine was partially flooded when a false report was received that it was on fire as well. Soon afterwards Lion was hit by a number of shells in quick succession, but only one of these was serious. A shell burst on the nine-inch armour belt abreast the engine room and drove a armour plate about two feet inboard and ruptured the port engine's feedwater tank. By 10:52 Lion had been hit fourteen times and had taken aboard some of water which gave her a list of 10° to port and reduced her speed. Shortly afterwards her port engine broke down and her speed dropped to . In the meantime Blücher had been heavily damaged by fire from all the other battlecruisers; her speed
