法兰西第二帝国时期是法国海军势力在远东地区迅速侵略扩张的关键时期。通过1857-1860年的“中国远征”，法国舰队最终实现了在中国海域由游弋型向常驻型的转变，期间亦有大量法国海军军官率舰来华。法国海军准将卜罗德的来华经历具有很强的代表性，其于1860年抵达中国后，先后作为高级指挥官参与了第二次鸦片战争和镇压太平军的“华洋会剿”活动，1862年在上海附近的南桥镇与太平军作战时中枪身亡。卜罗德死后，法方和清政府方面都举行了隆重的悼念仪式，上海教绅为其破格修建教堂，上海法租界更为其树立了纪念铜像。作为法国首位常驻中国的海军司令，卜罗德在清政府眼中自“夷酋”向“法督”的身份转变，充分折射出这一时期法国在华的利益变化和战略调整。将卜罗德来华两年间的言语行动、其与中外各界人士的联系交往以及其死后遗留给中法两国的零散记忆等内容，加以认真挖掘、整合与探究，方能更全面、深入地剖析其来华所产生的实际效应。在此基础上对卜罗德来华作多维度的考察，亦可揭橥中法两国于华洋初交之际，尤其于西风劲袭的上海，交涉、碰撞、相互正视、相互认识的历史进程中的诸多阙如之处，进而加强研究的厚度和广度。总而言之，卜罗德来华兼顾了法兰西第二帝国政府、法国天主教势力和上海法租界商人与侨民等不同群体的利益需求。作为法国远东战略的践行者，卜罗德充分执行了拿破仑三世对华采取的扩张型炮舰政策，巩固了法国在上海的长期军事存在；作为天主教会的合作者，卜罗德与法国教会势力互相利用，积极为传教活动提供“安全保障”，为这一时期天主教在中国的迅速渗透充当“保护伞”；作为上海租界及其侨民的守卫者，卜罗德不仅在太平军进攻上海期间翼护商人钱袋，更以“借师助剿”为砝码，为上海法租界当局攫取了扩界权和众多商业特权。结合时代背景考证其来华史事，可以增进对不平等条约下“战中有和，和中有战”的中法关系的深层次认识。通过分析其在上海法租界侨民心中被建构出的“拓垦者”与“保护神”形象，亦可反思法租界初创时期界内侨民的心态特征和情感认同。

The French Second Empire is a crucial period during which French Navy Force expanded rapidly in the Far East. French fleets had finally realized the positional transformation from mobile-type to regular-type in China sea areas through the China Expedition from 1857 to 1860. A number of naval officers came with their fleets at that period. The French Contre-Admiral Auguste Léopold Protet’s experiences in China has an especially strong representativeness. After his arrival in China at 1860, he got involved into the Second Opium War and a Sino-foreign joint operation against the Taiping Troops as a commander. In 1862, Protet was killed by Taiping Troops in Nan-kiao near Shanghai. After Protet’s death, both French Navy and Qing dynasty organized a solemn ceremony respectively. Catholic wealthy in Shanghai even made an exception by building a church for him, while Shanghai French Concession built a memorial bronze statue. As the first Commander in Chief of the French Naval Division in China Sea, The change of France’s interest in China and the subsequent modification of strategies can be observed through the transformation of Protet’s identity in the Qing Dynasty’s eyes, from “Barbarian Chieftain” to “French Commander”. Actual effect can be brought to light by a more comprehensive and deeper analysis, which can be produced only if Protet’s conversations and actions, interactions with people of all circles, and also a variety of memories left to both countries after his death in China, are conscientiously studied. A more thoroughly-analyzed examination of the Protet’s arrival in China can also expand the scope of the study by uncovering those unknown parts of the history progress of negotiations, collisions, confrontation and mutual knowledge between China and France, especially in Shanghai, where Western culture was prevailing, in the early stage of the establishment of diplomatic relations between both countries.All in all, Protet attended to the profit and interests of different groups in China, including The French Second Empire, the French Catholic force, businessmen and citizens who lived in the Shanghai French Concession. As a practitioner of French Far-Eastern strategy, Protet had succeeded in carrying out Napoléon III’s aggressive Gunboat policy to China, which resulted in more solid military existence in Shanghai. As a cooperator with Shanghai Catholic Church, Protet had offered protection to missionary activities to facilitate the quick spread of Catholicism in China. As a guard of Shanghai French Concession, Protet not only protected the interests of businessmen during the Taiping siege of Shanghai, but also obtained concession expansion rights and more commercial privileges by helping Qing dynasty to exterminate Taiping troops.Examining Protet's activities in China within the historical context will deepen the understanding of Sino-French relations at that time, which blends peace and conflicts under the unequal treaties. Analyzing the fact that he was regarded as a “exploiter” and “guardian angel” by the citizens in the Shanghai French Concession will also reveal the public mental features and emotional identification in the early stage of French Concession establishment.
