koreanhistory1-4, Exercise 1: The Silla-Tang War (a sample; yours will differ)

Model answer:

1. 668-669: the allies conquer Goguryeo (668, firm); the first Goguryeo revolt follows (669, firm). Tang rule over the former kingdoms is the cause of the quarrel.
2. 671: Silla drives Tang forces out of most of former Baekje (firm as stated).
3. February 675: Tang beats Silla at Chiljung Fortress (firm); September 675: the Samguk sagi reports a Silla win at Maeso over 200,000 men (hedged: Kim Byeong-Hee reads it as a Tang retreat and a symbolic figure; the Zizhi Tongjian omits it). The Cheonseong siege date is printed as "765", a typo.
4. November 676: Silla wins the naval battle of Gibeolpo (details unknown). The war ends as a "Silla victory" (infobox) or "a truce" (lead); Tang leaves the south of the Taedong.

Contradicted: the start (670 vs 668 in a cited work), the result (victory vs truce), Chinese vs Korean accounts of 674-675.
