March  UTC  What were the troop levels of Younghusband in  vs the PLA in  The PLA in  marched in four columns in how many columns  did Younghusband move I guess you could find plenty of differences on the operational level and I dont think you can find any WP policy calling for consistency or political correctness in article names I still think thre is sufficient evidence that Younghusband expedition is the most common name if you insist on moving the article it should be moved there Re whether the Tibetans signed that treaty because they lost the war I propose you look up the relevant literature My impression is the reason was not that they desperately wanted to join the PRC
