Heimdal16

AUSTRIAN SQUADRON.

Guns.
Schwartzenburg48
Radetzky31
Three Prussian gun-boats.

The two squadrons advanced in line ahead, the Danes coming up on the beam of the Austrians. The Niels Juel joined action with the Schwartzenburg, and the Jylland with the Radetzky, the Heimdal attempting to reach the gun-boats, which steamed up on the unengaged side of the frigates, causing the latter to steam in a circle. The action was fought in this manner, steaming in a circle of which the gun-boats were the centre and the Danes 600 yards outside the Austrians, the Heimdal joining in the attack on the Radetzky. After three hours, the Schwartzenburg was set on fire and the Austrians ran for Helgoland, the Danes hauling off at the neutral-ground limit. Indecisive action.
