Remarks :

Quick firing heavy gun. It was an improved version of the 10cm Kanone 04 with longer tube and a shield to protect. It had a modified recoil system, a new breech, a firing platform to allow a rapid direction aiming upon 360°, and two separate elevation aiming systems, one for the flat trajectories, and the other one for the indirect fire. Two batteries were converted for mountain transport, divided in two loads.

At the outbreak of war in August 1914 the Krupp gun went into service as the 10cm Kanone 14, with 128 pieces initially ordered. During the war, 724 of them were delivered by Krupp.  In May 1915 the first 10cm battery was re-equipped with 10cm K 14.

At the end of 1917 6th battery of 3rd heavy artillery regiment received 2 - 10cm K. 14, and at the beginning of August 1918 the German Army left to the Bulgarian artillery at least 12 of these guns from three batteries operating in Macedonia (2., 3., 4 Bt./R.FußAR. 16). The guns were assigned to 1st, 2nd and 3rd battery of 2nd heavy artillery regiment.
