The German 5.9 (150mm) heavy artillery piece, not a rail mounted equipment, had the necessary range. As a rough guide Ieper (Ypres) to Paschendaele in about 6 miles and some 5.9's could reach nearly 13. I dont know in any were deployed there.

The
15 cm schweres Feld=Haubitze ("heavy field howitzer") was a common piece, not sure of its exact range, 13 miles is a lot. You are right, there were different models with different ranges, and late in the war the Germans started making some long-barreled "howitzers" (sounds like an oxymoron) called something like
Kartouches. 15cm cannon (not howitzers) were rare and often naval cannon mounted on field carraiges. A more common long-range cannon were 10 cm
Kanone, and the gun weighed more than the 15 cm howitzer. There were the occasional other calibers of cannon with long range, some older guns, the most common was the 12 cm
Kanone, but there were the occasional 9 cm, 13 cm., and some batteries of captured cannon, especially Russian. Some of the older guns, some found with reserve formations (
Landwehr, etc.), had limited range.
Sorry, no clear answer there. There also were batteries of 21 cm howitzers, a corps-level weapon. 105 mm howitzers were common and were at divisional level field artillery regiment, but may not even had the range of the 77 mm field gun.
If exact ranges are required I have a resource some distance off.
