The wonderful hikari kaitou scanlated the comic from Himaruya’s blog!
Comic: “Early in the morning of 30 January 1658, the [Swedish] army was lined up to cross theLittle Belt to reach Funen. The army consisted of about 9,000 cavalrymen and 3,000 foot soldiers. The ice warped under the weight of the soldiers; on occasions water reached up to the men’s knees. Close to the shore of Funen a skirmish broke out with about 3,000 Danish defenders, but these were brushed aside quickly and the army was safe on Funen.” (wiki)
