Shipborne close quarters weapons of pre-modern Chinese navies

When people think of pre-modern naval warfare in China and to a lesser extend East Asia, most think of imposing tower ships raining arrows and stones against the opposing fleet, or masses of fire ships turning the sea into a raging inferno à la Battle of Red Cliff.

But there were more to Chinese naval warfare than just missiles and fire. Though often overlooked and understudied, naval battle at close quarters such as boarding action remained an important, even predominant, facet of Chinese naval warfare. In this article, I will introduce some of the tools and weapons used by Chinese navies for close quarters engagement.

Gou Ju (鉤拒, lit. 'Hook-resist')

Since naval boarding was the oldest and predominant form of military tactic in the age of pre-modern naval warfare, it is unsurprising that the earliest naval weapons ever devised were tools to facilitate boarding. Gou Ju, also known as Gou Qiang (鉤強), was a tool, or possibly a set of tools, developed during China's Warring States period and attributed to legendary Chinese carpenter and inventor Lu Ban (魯班). Although the exact design of Gou Ju is now lost, its purposes couldn't be more straightforward: to hook and pull over an enemy ship for boarding, and to fend and push away enemy ship to prevent boarding. As such, it most likely took the form of grappling hook and wooden push pole, or a combination thereof, i.e. something akin to a boat hook. Gou Ju was one of the principal naval weapons of State of Chu (楚國), which used the boarding tool to great effect against the navy of the rival State of Wu (吳國). In fact, military training for Gou Ju became a cultural pastime for the people of Chu state and remained observed long after the demise of the state, eventually evolved into tug of war sport in China.

Gou Ju became overshadowed by other, more advanced naval weapons as Chinese naval warfare became increasingly sophisticated, and largely disappeared from written records after the end of Warring States period. However, such useful tool(s) most definitely continued to see use, either in altered forms or under other names, for as long as naval boarding remained a viable tactic.

Zhuang Liang (撞梁, lit. 'Ramming beam') or Zhuang Gan (撞竿, lit. 'Ramming pole')

A curious and very obscure naval weapon, Zhuang Liang was essentially a wooden beam, longer than the ship's breadth, that was sodded with iron on both ends and built directly into the ship's hull, presumably by replacing one of the planks of its watertight bulkhead. The reinforced ends of Zhuang Liang jutted out from both sides of the hull and functioned as naval rams for the ship, although they were designed for lateral ramming rather than the more familiar head-on ramming. In fact, it may be the only weapon in the world purpose-built for such tactic, as side-mounted rams would seriously interfere with the rowing of oared vessels such as Mediterranean galleys, but won't present a problem for Chinese ships propelled by banks of yuloh (搖橹), as unlike normal oar, the blade of a yuloh is submerged at all time during sculling.

Zhuang Liang was one of the notable armaments of the powerful Wu Wei Chuan (烏尾船) fleet employed by notorious pirate lord Zeng Yi Ben (曾一本), which allowed him to pulverize Ming navy's Fu Chuan (福船) with ease. Fortunately, Ming navy was able to counter his formidable fleet by equipping the same weapon on its own purpose-built ironclad warships.

Naval ramming

Unlike their counterparts in the Mediterranean Sea, for the most part Chinese navies of the antiquities never seem to develop a specialised naval ram, and instead favoured fortified superstructures on warship to better capitalise on their advanced missile weaponry as well as to deter boarders. The formidable yet ponderous Lou Chuan (樓船) and its many derivatives, packed to the brim with commanding firepower yet ill-suited for ramming, thus remained a staple of Chinese navies for thousands of years.

Only sporadically used in the preceding dynasties, naval ramming suddenly became more popular during Ming period, where it was described as Chong Li (衝犁, lit. 'Charge and plough') or simply Li (犁, lit. 'Ploughing'). Curiously, this only happened after older oar-powered ships were largely phased out by sailing junks, and ramming was largely abandoned by navies elsewhere. The reason for this change is unknown, although it may be related to the primary naval threat faced by Ming Dynasty at the time: the Wokou (倭寇) or Japanese pirates. To elaborate, Japanese ships were considered rather shoddily built by Chinese standard and could be easily destroyed in a collision, which probably enabled ramming to become a viable tactic. This is indirectly supported by the fact that Ming military thinkers never seem to bother with ramming prevention/defence or military formations designed around ramming tactic, as the underlying assumption seem to be that ramming was one-sided, and Ming ships were largely safe from retaliation.

Still more questions remain. For example, how was ramming conducted with typically flat-prowed sailing junks without a ram? How did Chinese ship captains avoid the common pitfalls associated with ramming, such as getting stuck in the hull of the ramming target? Fortunately, a late Ming period military treatise, Bing Lu (《兵錄》), sheds some light on these questions, and the solution was surprisingly simple and ingenious: anchor.

It turns out instead of designing a purpose-built ram, Chinese sailors simply used secured anchors as rams instead. Traditional Chinese anchors, of both arrow-shaped wooden and four-clawed iron varieties, could weigh anywhere from 400 kg to 800 kg (for comparison, the Athlit bronze ram, the largest naval ram ever discovered, weighs 465 kg) and equipped with long arms to prevent overpenetration, which made for an ideal ramming weapon. In addition, anchor had the added benefits of being readily available on practically every ship, and could be easily cut loose if it somehow got stuck.

Using anchor as ram was only possible with a Chinese junk, thanks to its flat prow allowing an anchor to be directly fixed to the prow of the ship (ships with curved/pointed prows, or those with long bowsprits, generally required a cathead to secure the anchor to the side of the ship, thus unable to utilise it for ramming). Moreover, many war junks like Fu Chuan typically had multiple anchors, which made their ramming all the more devastating.
