The strip of grass and sand along the Jin boundary trench from the Xar Moron plateau at Linhuang north-east to the Nonni plain at Taizhou, where the Jin's Khitan and Xi jiu horse and Jurchen frontier garrisons face the Tatars and Onggirat of the Buir Nur and Khalkha and the hunters behind the Khingan.
In 1195-1196 the Jin fought the Onggirat and then the Tatars here, the Onggirat invaded the Jin on 4 February 1196 and Wanyan Anguo held the Kherlen for three days (English Wikipedia, Jin dynasty); the Tatar chief Zuxu submitted in 1198, rebelled and submitted again. A Khitan rising troubled the same country in 1196-1198 (leaders and place not pinned). The belt is a standing frontier, not an active front: we found no raid, revolt or campaign recorded here for the winter of 1199-1200, and the last known fighting is of 1198.

How things stand that morning
Tense and watched, not at war.
Raiders and victims
Tatars and Onggirat raid the Jin edge in bad years and the Jin and its Kereyit and Mongol helpers raid back; Khitan malcontents join either side. The Jin garrisons and jiu horse hold the line.
Anchors on each side
Jin side: Linhuang fu, the trench forts of the Linhuang line, Taizhou (the Dongbei commission), Ulanhot country. Steppe side (Mongolia sheet): the Tatars of the Buir Nur, the Onggirat of the Khalkha and Ergune, the Mongols of the Onon and Kherlen.
Last campaign
1198: the Tatar submission after the war of 1195-1198 (English Wikipedia). Nothing recorded for 1199.
Where the sources disagree
Evidence: The 1195-1198 war is attested in English Wikipedia (read); winter 1199-1200 is silent in everything we could read. The belt marks a standing danger zone, not a documented raid.
On the map: The true trench line lies on the Mongolia sheet's edge; the strip here is the Jin side of the belt. Do not read 'raided' as an active campaign in January 1200.
