The Southern Joyonghean Campaign, codenamed by the Quenminese as Operation Ðien Bí, was a Quenminese military offensive conducted by Quách Khánh Thắng Due. Its objective was to force the Allies with their backs to the Sea of Nanja and swing east to squeeze the entirety of the Allied forces given Ông Thao Pin's advance from Kunsan. From 25 May to early June, the Quenminese took advantage of the Allied retreat and pushed them near the coast. Contributing to this However, 15 to 27 June saw the Allied putting a defense with a close call on the 25th. Until 19 July, the Allied began to push the Quenminese forces back, and forced Due to withdraw north once more.

Alongside continued resilience from the Allied personnel, the rearming of the Joyongheans with up-to-date Commonwealth arms such as the Lena-Elfield rifle contributed to the stalling of Quenminese advances during the stalemate period.
