A [slightly more] well prepared Danish fleet
[P.o.d.: The Danish ships anchored at the 'Inner Run' of Copenhagen's harbour are readied on time. Effective from time listed below and probably involves the Swedish Navy fighting with the Danes.]
At 12:00, a very small fleet of Danish ships was seen moving to the south and supported by fire from 2 blocking ships [that were later destroyed by frigates]. The ships involved [2 each of brigs and modern battleships] soon found themselves engaged with HMS Monarch and Defiance, inflicting severe damage. HMS Ganges suffered heavily from gunfire from 3 ships of the line and was nearly shelled to wreckage had it been not for supporting ships [it would be reconstructed while in dockyard later]. A smaller 50-gun ship of the line was almost sunk, but rescued by the intervention of HMS Bellona. Later, Bellona had to be towed away by another grounded ship and the smaller ship was sunk while returning home, having grounded earlier with heavy casualties. HMS Elephant was engaged with the Danish flagship and several others in support.
After Danish resistance was stopped by 16:40 hours, the Danish Navy had lost a flagship to an explosion, 6 immobile and 2 mobile ships of the line and all the smaller vessels in the defence fleet, plus a few fortresses by 17:00 hours while the British lost 2 ships of the line for some time [one sunk and the other in need of rebuilding after decommissioning]. Copenhagen had to surrender, but the Swedish efforts to engage the British fleet and the loss of many Swedish and Danish ships terminated the League of Armed Neutrality. [Or HMS Monarch and Ganges to fortresses after heavy damage received earlier.]
It was revealed that the British were planning to bribe the Russians with prizes, northern Norway and Finland should the League continue its course, but it was terminated. 2 Swedish and 4 Danish ships of the line ended up as prizes and were evaluated for construction, the rest being burnt. After the losses of ships, British threats and the assassination of the League's mastermind, both enemy fleets were disarmed.
