Several minutes after opening fire, Holland ordered a 20° turn to port, which would allow his ships to engage with their rear gun turrets. Both German ships concentrated their fire on Hood. About a minute after opening fire, Prinz Eugen scored a hit with a high-explosive 20.3 cm (8.0 in) shell; the explosion detonated unrotated projectile ammunition and started a large fire, which was quickly extinguished.[58] After firing three four-gun salvoes, Schneider had found the range to Hood; he immediately ordered rapid-fire salvoes from Bismarck's eight 38 cm guns.
