Dietrich of Tarnburg was successful on the fields of Cardonicus
No clues as to precisely where it is located, or anything further about it.
“So is Dietrich of Tarnburg, of the high city of Tarnburg, some two
hundred pasangs to the north and west of Hochburg, both substantially
mountain fortresses, both in the more southern and civilized ranges of
the Voltai, was well-known to the warriors of Gor. His name was almost
a legend. It was he who had won the day on the fields of both Piedmont
and Cardonicus, who had led the Forty Days’ March, relieving the siege
of Talmont, who had effected the crossing of the Issus in 10,122 C.A.,
in the night evacuation of Keibel Hill, when I had been in Torvaldsland,
and who had been the victor in the battles of Rovere, Kargash, Edgington,
Teveh Pass, Gordon Heights, and the Plains of Sanchez. His
campaigns were studied in all the war schools of the high cities. I knew
him from scrolls I had studied years ago in
Ko-ro-ba, and from volumes in my library in Port Kar , such as the
commentaries of Minicius and the anonymous analyses of “The Diaries,”
sometimes attributed to the military historian, Carl Commenius, of
Argentum, rumored to have once been a mercenary himself.

. At Rovere and Kargash Dietrich coordinated his air and ground cavalry in such a way as to force his opponents into sturdy but relatively inflexible defensive squares. He then advanced his archers in long, enveloping lines, in this way they could muster a much broader front for low-level, point-blank firepower than could the narrower concentrated squares.
He then utilized, for the first time in Gorean field warfare, first at Rovere, and later at Kargash, mobile siege equipment, catapults mounted on wheeled platforms, which could fire over the heads of the draft animals. From these engines, hitherto employed only in siege warfare, now became a startling and devastating new weapon, in effect, a field artillery, tubs of burning pitch and flaming naphtha, and siege javelins, and giant boulders, fell in shattering torrents upon the immobilized squares
