Greater importance was placed at this time on development of the army, which was expected to be more important in any war. However, the Kiel Canal was commenced in June 1887, which connected the North Sea with the Baltic through the Jutland peninsula, allowing German ships to travel between the two seas avoiding waters controlled by other countries. This shortened the journey for commercial ships, but specifically united the two areas principally of concern to the German navy, at a cost of 150 million marks.[1]
