gunboats. Kanonchaluppen: These were the larger type of gunboat. Each was armed with two 24-pounder cannon and four 4-pounder howitzers and had a wartime establishment of 69 – 79 men. Kanonjollen: These were the smaller type of gunboat. Each was armed with one 24-pounder cannon and two 4-pounder howitzers, and had wartime establishment of 41 men. Morterchaluppen: These were the larger, mortar-armed gunboats. Each was armed with one 100-pounder mortar and two 4-pounder howitzers, and had a wartime establishment of 40 men. Morterbarkasserne: These were smaller, mortar-armed gunboats. Each was armed with one mortar and had a wartime establishment of 19 men. They were little more than ordinary ships' boats into which a mortar had been set. They had a tendency to leak badly after 5 – 7 mortar shells had been fired. Their crews then had to bring them back into harbour, remove the mortar, and recaulk their vessels. Reserve crew who could not be accommodated on board were quartered in buildings on land or in the frigate Triton which was in ordinary. Battle-ready gunboats had their crews on board. Defences on the Norwegian coast in 1808 are listed at Royal Dano-Norwegian Navy order of battle in Norway (1808). Ten schooner-rigged gunboats capable of operating in the rougher Norwegian Sea were built in Bergen and Trondheim in the years 1808 to 1811. War In the first three years of the Gunboat War, these boats were on several occasions able to seize enemy cargo ships from their convoys and to capture British brigs, though they were not strong enough to overcome larger frigates and ships of the line. The British had control of Danish waters during the whole of the 1807–1814 war, and when the season was suited to navigation they were regularly able to escort large merchant convoys out through the Sound and the Great Belt. Although the discussion below focuses on armed encounters involving an exchange of fire, one must keep in mind that the British also captured numerous Danish privateers without firing a shot, and regularly seized Danish merchant vessels as prizes. The British also conducted amphibious landings on several Danish islands, many populated but lacking garrisons. British warships frequently landed to replenish their stocks of firewood, fresh water and livestock, which were purchased or seized to augment their provisions. The war overlapped, in time, the Anglo-Russian War. As a result, the British expanded their trade embargo
