Oxford: BAR Publishing, 2017. Naval Warfare of the Ming Dynasty (1368–1644): A Comparison Between Chinese Military Texts and Archaeological Sources Elke Papelitzky University of Salzburg Abstract: During the Ming dynasty, a great number of military treatises were written. They sometimes include strange and fantastical information like pictures of sword-fighting monkeys, which cast doubt on their representation of reality. A comparison with archaeological sources might shed light on the credibility of these texts. A suitable topic for this comparison is the armament of ships, as the question: ‘What kind of weapons did ships carry?’ can be asked to both the archaeological as well as the textual sources. In this paper, I compare the weapons described in the texts with those found in excavations of shipwrecks. In addition, I address the question about the meaningfulness of such a comparison. I argue that while certain elements are the same in the textual and the archaeological record, it is better to not compare these two types of sources but rather use them alongside each other to complement the picture. The question of the credibility of texts is better addressed by textual analysis and a study of the biographies of the authors. Key words: Naval warfare; Ming dynasty; China; Comparison of texts and archaeology; Military writing During the late Ming dynasty, China faced frequent attacks both from the sea by so called Japanese pirates,1 as well as from the Northern border by Mongols and Manchus, who eventually conquered China and established the Qing dynasty (1644–1911). This increased threat as well as a publishing boom resulted in a great number of military treatises being written, of which many still survive today. The authors of these texts were both generals of the Chinese military as well as literati interested in military affairs and their writings are an important source for the military and intellectual history of the late Ming period. The texts include valuable information on troop arrangements, tactics for fighting, organising of provisions, information on the foreign enemy and any other possible information a general in the late Ming would have needed to be well prepared for battle. However, sometimes weird and fantastical information finds its way into the texts like pictures of sword fighting monkeys (see figure 1) 2 or rockets that would not be able to fly in a straight line, 3 which cast doubt on the credibility of the texts and call for further clarification. One possible method to evaluate the textual sources is to compare them with the archaeological record. It is of course not possible to compare the tactics or the organisation of the troops with archaeological sources, but the many descriptions of weapons are something where parallels between the textual and the archaeological records can be drawn. Especially the topic of the armament of ships is very suitable for a comparison, as the texts give very clear information on the employment of weapons for naval warfare and the discovery of shipwrecks with weapons also leave no doubt about the use of these weapons on ships. These pirates are called wokou 倭寇 in Chinese (Japanese reading: wakō). The term literarily translates to “Japanese bandits.” However, especially during the later Ming period, a great percentage of these pirates were not Japanese but rather Chinese. 2 Mao Yuanyi 茅 元 儀, Wubeizhi 武 備 志 (1621), j. 86, 17a–18b, Accessible online through Chinese Text Project http://ctext.org/library.pl?if=en&res=2523. While there is a logical explanation for the inclusion of the monkeys – a short introduction before the pictures explains that they are representing a “monkey style” of sword fighting – a direct comparison with Mao Yuanyi’s source, the Jixiao xinshu 紀效新書 reveals that while the introductory text on the fighting style is the same, the Jixiao xinshu does not include any pictures of monkeys but instead uses schematic representations of humans. This does not necessarily mean that Mao Yuanyi believed in fighting monkeys, but it reinforces the strangeness of the text and shows that he, or at least the person drawing the pictures, was not completely committed to accuracy (Qi Jiguang 戚繼光, Jixiao xinshu. Shisi juan ben 紀效新書. 十四卷本, ed. Fan Zhongyi 範中義 [Beijing: Zhonghua shuju, 2001], 83). 3 Mao Yuanyi, Wubeizhi, j. 133, 3a–4b. I will discuss this rocket in more detail below. 4 In China this discussion was started in the early 20 th century by Wang Guowei 王國維 and his method of dual evidence (erchong zhengju fa 二 重證據法), which he applied mostly to excavated texts as opposed to texts transmitted through the ages. Other important examples include K. C. Chang’s Shang Civilization or the discussion in the introduction of The Cambridge History of Ancient China. A recent volume dedicated especially to the theoretical aspects of combining the two types of source in the Asian context was edited by Yoffee and Crowell Kwang-Chih Chang, Shang Civilization (New Haven and London: Yale University Press, 1980); Michael Loewe and Edward L Shaughnessy, eds., The Cambridge History of Ancient China. From the Origins of Civilization to The combining of textual and archaeological sources has led to long discussions between historians and archaeologists, especially concerning early periods of history with sparse textual sources. 4 However, regarding 1 1 Left hand page header Jixiao xinshu 紀效新書 (A New Treatise on Military Discipline and Efficiency) by Qi Jiguang 戚繼光, c. 1560.8 Chouhai tubian 籌海圖編 (Illustrated Naval Strategy) by Zheng Ruozeng 鄭若曾, 1562.9 Wubeizhi 武備志 (Treatise on Armament Preparations) by Mao Yuanyi 茅元儀, 1621.10 the Ming dynasty, a period where ample textual records exist, there are very few historians that supplement the textual records with a close study of archaeological data. A notable exception, also concerning the history of Chinese warfare, is of course Joseph Needham’s famous series Science and Civilisation in China, in which he carefully combined written texts, archaeological sources, and natural sciences.5 Other examples are Sun Laichen’s studies on gunpowder weapons in Southeast Asia. 6 The up to now most comprehensive study on naval warfare was done by Zhang Tieniu and Gao Xiaoxing. They supplement the historical record with some information on excavated weapons, but these objects mainly serve to illustrate the information Zhang and Gao draw from the Ming dynasty texts. They do not include any detailed discussion on the provenance of the weapons or on shipwrecks and their book, thus, cannot be considered a detailed study of the archaeological record.7 The well-known general Qi Jiguang (1528–1588) fought both against the pirates as well as against the Mongols. The Jixiao xinshu incorporates his experience training the troops against the pirates and includes first-hand knowledge of naval warfare. Zheng Ruozeng (fl. 1505–1580) was a very diligent scholar, whose goal was to contribute in some way to the Chinese society. He wrote the Chouhai tubian in response to the ongoing attacks of the pirates and collected all the source materials on the topic he could find. The Chouhai tubian is one of the most detailed known collections on the pirates. Relating to this present volume about bridging the divide between interdisciplinary boundaries, I want to contribute to filling the gap between the archaeological and historical data and compare the two kinds of sources concerning the armament of ships. In addition, I will discuss methodological problems one faces when comparing these two types of sources and address the question of the meaningfulness of such a comparison. Mao Yuanyi (1594 – c. 1641) followed a military career and is especially known for having fought against the Manchus. The Wubeizhi is a collection of various military texts and incorporates knowledge from earlier sources like the Song dynasty (960–1279) Wujing zongyao 武經總要. It is the longest of the three works discussed here.11 The textual sources The texts and authors There are several editions of the Jixiao xinshu. The earliest edition was completed in 1560, still missing the chapter on naval warfare. An edition in 18 juan (chapters) was printed by the author around 1562. This edition was reprinted multiple times during the Ming and Qing dynasties and was included in the Siku quanshu 四庫全書 collection. There is also a revised version in 14 juan, published in 1584. There are annotated and punctuated versions of both the 14 and 18 juan versions (Qi Jiguang 戚 繼光, Jixiao xinshu. Shiba juan ben 紀效新書. 十八卷本, ed. Cao Wenming 曹文明 and Lü Yinghui 吕穎慧 [Beijing: Zhonghua shuju, 2001]; Qi Jiguang, Jixiao xinshu. Shisi juan ben). For more information on the different editions see Qi Jiguang, Jixiao xinshu.

I have primarily used the 18 juan Siku quanshu edition. 9 The Chouhai tubian also was reprinted several times during the Ming and Qing dynasties and included in the Siku quanshu. There also is a modern punctuated edition prepared by Li Zhizhong based on a later Qing edition.

There is no annotated edition of the complete work. For more information see Franke and Liew-Herres, Annotated Sources, 636f. The Jixiao xinshu and Wubeizhi are also shortly discussed in Ralph D.

I will focus on the following three well-known military treatises from the late Ming that include information on naval warfare: 221 B.C. (Cambridge: Cambridge University Press, 1999); Norman Yoffee and Bradley L. Crowell, eds., Excavating Asian History. Interdisciplinary Studies in Archaeology and History (Tuscon: University of Arizona Press, 2006)]. 5 For this paper, especially Volume 5, part 7 on gunpowder weapons is important (Joseph Needham, Science and Civilisation in China.

Another overview in English over the history of Chinese naval warfare was prepared by Peter Lorge (“Water Forces and Naval Operations,” in A Military History of China, ed. David A. Graff and Robin Higham, Updated Edition. [Kentucky: University Press of Kentucky, 2012], 81– 96). 2 Header right page 面 神 威 風 火 砲, the Portuguese-style folangji, and a Chinese-style cannon), a curious rocket in the shape of a dragon (huolong chushui 火 龍 出 水), several types of mines and other fire devices, as well as a kite in the form of a bird equipped with fire-arrows to set enemy ships or sails on fire. The bamian shenwei pao (invincible cannon firing in eight directions) is said to be able to fire in all eight cardinal directions – something that Needham supposes is an exaggeration, as it would require very advanced technology to build a suitable frame. 19 Even more fantastical is the rocket in the shape of a dragon. Four fire-arrows are said to be attached to its main body which launch the rocket into the air once ignited. Sawyer expresses doubts over the actual usability and existence of this weapon, as one had to ignite all fire-arrows at the same time, otherwise the missile would not fly a straight route.20 He is equally doubtful about the existence of the bird-kite since, as he puts it: “it is an odd contraption more expressive of simplistic thinking – flight means wings, therefore imitate birds – than weapons development, especially since rockets and large rocketpowered incendiary arrows already existed.”21 Weapons described in the texts Concerning weapons used on ships, these texts provide us with lists of equipment for ships, with detailed descriptions and illustrations of such weapons, as well as with pictures of ships showing soldiers holding weapons. The exact contents vary widely between the texts. The Jixiao xinshu has a whole chapter dedicated to naval warfare. Especially important are detailed lists of the equipment of ships. Qi Jiguang lists various cannon: Ships are supposed to carry one very large cannon (da fagong 大 發貢), six Portuguese-style cannon (culverines – folangji 佛郎機) and three Chinese-style cannon (wankoutong 碗 口 筒). In addition to these cannon, the list adds arquebuses as well as various other fire and gunpowder weapons as well as non-gunpowder weapons like bows and javelins.12 Later in the chapter, Qi Jiguang explains in detail how some of the gunpowder weapons function.13 In its last chapter, the Chouhai tubian has several pictures of different ships, as well as information on weapons. Among the weapons mentioned for naval warfare are the Portuguese-style folangji, a large bronze cannon (see figure 2; probably the same as the da fagong from Qi Jiguang’s list), some mines and different kinds of arrows. The descriptions are very detailed and include schematics of disassembled weapons. 14 Especially the note on the large bronze cannon is interesting, as it warns of the dangers of using this cannon: It is so powerful that one risks damage to one’s own ship if the soldiers are not careful. 15 There are illustrations of 17 different kinds of ships, of which the majority shows soldiers standing on the deck holding weapons. The weapons shown are spears, swords, bows, and handguns. None of the illustrations shows any cannon (see figure 3).16 Archaeological sources Methodological problems We know of several shipwrecks found in the oceans in East and Southeast Asia that date to the Ming dynasty with findings of weapons. While in contrast to the texts, there is no doubt that these weapons actually existed and were used aboard ships, there are several other methodological problems one encounters when discussing the armament of Chinese warships. The largest problem concerns the origin of the wrecks. As the texts only write about Chinese ships, only wrecks that come from China are suitable for comparison. This is, however, not easy to ascertain. While Chinese shipbuilders used different techniques than these in Southeast Asia, so that the hull of the ship can be identified as either Southeast Asian or Chinese, the hull is not always extant in all ships. 22 In addition, there is no information about the crew – Chinese people might have used a ship built in Southeast Asia, something that is not unheard of for Ming dynasty merchants, although it seems unlikely for warships.23 Information on naval warfare in the Wubeizhi is scattered throughout the work. The chapters 116 to 118 are dedicated to naval warfare. They include pictures of ships similar to those in the Chouhai tubian17 and descriptions of weapons made especially for naval warfare. In chapters 119 to 134 Mao Yuanyi describes various gunpowder and other incendiary weapons and for some of them he includes a note about their usability for naval warfare. The descriptions in the chapter on naval warfare include hooked spears for attaching to an enemy ship to stop it from escaping as well as two kinds of javelins. 18 The fire weapons shown in the other chapters are different kinds of cannon (a cannon called bamian shenwei fenghuo pao 八 Another problem is that not all shipwrecks are from warships. Indeed, the majority of excavated shipwrecks Qi Jiguang 戚繼光, Jixiao xinshu 紀效新書 (c. 1562), j. 18, 11b–16b, In Qinding siku quanshu 欽 定 四庫 全 書.

Before attempting a comparison, it is, thus, necessary to identify the purpose of the ship. This can be done by looking at the cargo – if the ship carried a lot of ceramics, one can assume that it was a trade vessel. found in the wreck.26 Even though it was not a warship, the fact that the people who used the weapons were soldiers and not merchants makes this wreck a valuable source for comparison. This shipwreck predates the military treatises by around 200 years, but shows us several things: Gunpowder weapons were used alongside non-gunpowder weapons and there was a wide range of different non-gunpowder weapons. The findings of the hooks support the evidence of the Wubeizhi about the existence of hooked spears for naval battles. The conditions in the seawater also make it nearly impossible for some of the incendiary weapons made out of paper or wood to be preserved. While wood and even paper sometimes do survive the harsh conditions in the ocean, with the overall very scarce number of findings the probability of finding such weapons is extremely low. In Penglai County in Shandong, archaeologists excavated four wrecks dating to the Yuan and Ming periods in 1984 and 2005. Here, especially the wreck Penglai no. 1, a warship dating to the mid to late Ming, is relevant. This is, thus, a warship roughly contemporary with the texts. The archaeologists found several weapons: a fragment of a bronze cannon, two iron cannon, iron and stone cannonballs in different sizes, bottles filled with quicklime, and a sword. 27 Quicklime was an important ingredient for incendiary weapons and there is evidence in Chinese texts that vessels filled with quicklime served as bombs.28 All three cannon have rings along the barrel and are of Chinese design.29 While these ringed cannons are described for example in the Wubeizhi, 30 they are not marked as weapons for naval warfare. The wrecks The wrecks that are most suitable for a comparison with the textual sources are the Liangshan 梁山 wreck, the Penglai 蓬萊 no. 1 wreck, and the Shenhu Bay 深沪湾 wreck. The Liangshan wreck was discovered in 1956 in the former Songjin River 宋 金 河 in Shandong 山 東. The excavation yielded several weapons: one bronze handgun, five swords, two spearheads, 20 arrowheads, 13 hooks from hooked spears and various other pieces of equipment. The gun bears an inscription, which dates it to 1377. As there are no items dated later than the fourteenth century, the ship probably sunk at that time. 25 In the original report, the excavators assumed that it was a military vessel, but recent research points to a ship used for transporting grain from the fertile region in the south to Beijing. Soldiers stationed on the ship to defend the valuable cargo from bandits probably used the weapons The Shenhu Bay wreck was discovered in 1999 near the coast of Fujian 福 建. The excavators did not recover many objects from the wreck, but among them were two inscribed cannon and part of an arquebuse. The cannon bear the dates 1553 and 1645 respectively. Judging from these inscriptions, the ship must have sunk in the late seventeenth century and, thus, dates to around 100 years later than the Jixiao xinshu and Chouhai tubian and only a bit later than the Wubeizhi. 31 As there are no traces of trade items but two cannon, the excavators assume that it was a warship. 32 The 1553 cannon is a Chinese-style muzzle loader and the 1645 cannon clearly shows European influences. From this wreck, we can see that cannon were used for a long time, even though newer technology was available. The Shenhu Bay wreck also Important trading vessels from the Ming dynasty that include weapons are the Bakau wreck (early 15th century), the Brunei wreck (end of 15th / beginning of 16th century), the Lena shoal wreck (sunk c. 1490), the Xuande wreck (sunk c. 1540) and the Nan’ao I wreck (end of 16th / beginning of 17th century). The weapons excavated from these ships include a range of guns as well as a folangji cannon, showing that not only military ships, but also merchant ships were equipped with powerful weapons (Michael Flecker, “The Bakau Wreck: An Early Example of Chinese Shipping in Southeast Asia,” The International Journal of Nautical Archaeology 30, no. 2 [2001]: 221–30; Michel L’Hour, ed., La mémoire engloutie de Brunei, 3 vols.

Conclusion In the case of the armament of Chinese ships, one can ask the same question to both written and archaeological sources: ‘Which kind of weapons did ships carry?’ Naturally, one would expect to find a similar answer from both sources. Indeed, a certain set of answers is the same from both sources: Chinese ships carried gunpowder weapons as well as non-gunpowder weapons; Chinese style-weapons were used alongside European-style weapons; and certain types of weapons appear in both types of sources. However, at this point, the similarities stop. We find in the archaeological record weapons like the handgun or the ringed cannon that the texts do not explicitly describe as weapons for naval warfare. We gain knowledge about their material and the size and we learn that one single cannon could be employed for around 100 years. The texts describe weapons that did not survive until today, how they were used, and to what specific problems the soldiers had to pay attention to. While this is interesting and valuable information, it only helps us answering the question of the credibility of the texts to some extent. It is especially problematic that the rather fantastical weapons like the dragon-shaped rocket or the kite would be made out of paper and other easily degradable materials, hindering a comparison with archaeological material. In fact, it seems easier to establish the credibility of the texts by looking at the sources themselves as well as the biographies of the authors. In the Jixiao xinshu and the Chouhai tubian, we look in vain for any unbelievable weapon. Only Mao Yuanyi records strange accounts in the Wubeizhi, where there are several of such weapons like the cannon that can fire in all directions or the rocket in the shape of a dragon. This might be due to the nature of the Wubeizhi: It is a collection of different sources, some even centuries old in the late Ming. Mao Yuanyi’s aim was to collect as much as possible and make a comprehensive, encyclopaedic work without necessarily checking the accuracy of the sources. Especially the illustrations are not necessarily an accurate depiction of reality. Qi Jiguang on the other hand recorded his personal experience fighting against the pirates. The inclusion of false information is unthinkable. The Chouhai tubian is a case in-between: it is a collection of sources like the Wubeizhi, but Zheng Ruozeng followed a different approach than Mao Yuanyi. He did not try to collect everything concerning military tactics, but only things that were usable in dealing with the pirates. This again led to a far more truthful account. The fact that we can establish the credibility of the texts by looking at the texts themselves does not mean that a simultaneous study of the different types of sources is worthless, but that rather instead of comparing the sources and using one type to validate the other, it seems more fruitful to use them alongside each other at equal importance. In this way, each type of source can fill the gaps the other leaves, demonstrating the importance of interdisciplinary work and of bridging the divide between Figure 1. Sword-fighting monkeys from the Wubeizhi (j. 86, 18a). historical and archaeological sources. Figure 2.
