Du Zhan Qian Li Che (獨戰千里車)

A badly drawn illustration of Du Zhan Qian Li Che, from 'Wu Bian Qian Ji (《武編前集》)'.

Du Zhan Qian Li Che (獨戰千里車, lit. 'Wagon that can fight alone for a thousand li') was a six-wheeled gun-armed mobile fortress designed to combat Wokou and Mongol raiders alike. Unlike most other Ming war carts and wagons, it was not designed to form a wagon fort, but rather to operate alone or in small groups.

Du Zhan Qian Li Che featureed a rather odd wheel configuration. It had two pairs of wheels like normal wagon, but also had one extra front wheel and one extra rear wheel, which allowed it to traverse rough terrains such as narrow path and log bridge. Its fully enclosed body was made of wooden frame covered in protective leather screens measuring five chi tall by five chi wide, and was equipped numerous gun loops on all sides. The wagon could be further equipped with spikes and hooks mounted around its chassis, as well as two cannons at its front and rear for additional firepower.

It should be noted that the source of locomotive power of this wagon was not explained. The name implied that this wagon was pushed by its passengers from the inside, although it should be possible to equip the wagon with yoke and shafts so that it could be pulled by draught animals.
