The Danes, meantime, had not been idle: no sooner did the guns of Cronenburgh make it known to the whole city that all negotiation was at an end, that the British fleet was passing the Sound, and that the dispute between the two crowns must now be decided by arms, than a spirit displayed itself most honourable to the Danish character. All ranks offered themselves to the service of their country; the university furnished a corps of 1200 youth, the flower of Denmark--it was one of those emergencies in which little drilling or discipline is necessary to render courage available: they had nothing to learn but how to manage the guns, and day and night were employed in practising them. When the movements of Nelson's squadron were perceived, it was known when and where the attack was to be expected, and the line of defence was manned indiscriminately by soldiers, sailors, and citizens. Had not the whole attention of the Danes been directed to strengthen their own means of defence, they might most materially have annoyed the invading squadron, and perhaps frustrated the impending attack; for the British ships were crowded in an anchoring ground of little extent:--it was calm, so that mortar-boats might have acted against them to the utmost advantage; and they were within range of shells from Amak Island. A few fell among them; but the enemy soon ceased to fire. It was learned afterwards, that, fortunately for the fleet, the bed of the mortar had given way; and the Danes either could not get it replaced, or, in the darkness, lost the direction.
