# 永乐城之战（夏军围城破宋）｜素材说明
|
||
|
||
## 事件边界
|
||
|
||
- 规范事件名：永乐城之战（夏军围城破宋）
|
||
- 常用称呼：永乐城之战、永乐城之败、夏破徐禧军
|
||
- 项目归类：西夏
|
||
- 时代：宋神宗元丰五年、西夏大安八年
|
||
- 日期：公元1082年九月
|
||
- 地点：银州故地永乐城、无定河一带
|
||
- 一句话结论：宋将徐禧在西夏边地仓促修筑永乐城，城防与水源尚未完备即遭西夏大军包围；夏军控制水源并发动攻城，永乐城陷落，徐禧等战死，宋朝此前五路伐夏所得优势受到重挫。
|
||
|
||
## 60–90 秒主旁白
|
||
|

元丰五年，宋朝在前一年五路伐夏之后，试图把新取得的横山地区变成永久防线。给事中徐禧选择在银州故地附近修筑永乐城，希望从这里控制通往西夏腹地的道路。城池修得很快，却离可靠水源较远，外围堡寨和补给体系也没有完全建立。西夏方面很快集结军队反攻。夏军包围永乐，控制无定河方向的取水通道，并击败前来增援的宋军。城内人口和军马在缺水中迅速失去战斗力。徐禧仍试图守城，但城墙在连续攻击下被突破。永乐城陷落，徐禧、李舜举等官员将领战死，大量军民未能撤出。宋神宗收到败报后震动，朝廷对西北扩张转为谨慎。永乐城之败不是一座城“选址不好”这么简单：它暴露了快速筑城、深入占领与后方运输之间的矛盾。宋军可以在地图上向前推进一座城，却未必能在沙碛、河谷和敌军反攻中持续供水、供粮并保住它。

|
||
### 01｜急筑永乐·水源在外
|
||
|
||
- 时间地点：银州故地与无定河边
|
||
- 本幕作用：建立城池仓促修筑和水源距离这一结构问题。
|
||
- 分幕旁白：徐禧督建永乐城，土墙和仓库迅速成形，取水路线却延伸到城外河谷。
|
||
- 页面标题：城先建好，水还没接上
|
||
- 页面短句：边墙能在数周内合拢，日复一日的粮与水却必须经过敌境。

|
||
- WebP：`images/01-song-builds-yongle-fort-away-from-water.webp`
|
||
- 替代文本：干燥横山边地，宋军役夫正在夯筑规模克制的永乐城土墙，城内仓库尚未完工；一列驮水骡车沿长坡通向远处无定河，山脊上可见少量西夏斥候。
|
||
- 视觉推演边界：城墙完成度、仓库状态、河距与斥候位置为视觉重构；徐禧筑永乐城、取水不便与夏军侦察有史载。
|
||
- 人物：徐禧（宋给事中、永乐城主持者；选址并督促快速筑城）；宋军役夫（军士、民夫与工匠；夯土筑墙、修仓与运水）；西夏斥候（侦察骑兵；从远处观察取水和运输路线）
|
||
- 史料：《宋史·神宗本纪》卷十六；《宋史·徐禧传》卷三百三十四

Use case: historical-scene. Digital Me Southern Song, Western Xia and Jin story frame. In the dry Hengshan frontier, Song laborers rapidly ram earth for the modest Yongle fort while storehouses remain unfinished. A long line of water pack animals descends toward the distant Wuding River; a few Western Xia scouts observe from a ridge. Make the exposed water route visually central. No mature giant city, modern aqueduct, desert fantasy, construction machinery or combat yet. Premium live-action Chinese historical film still, archaeology-informed eleventh-to-thirteenth-century East Asia, cinematic 16:9 landscape, subtle film grain, physically plausible troops, cities, rivers, ships and logistics, packed earth, aged timber, hemp, low-sheen silk, leather, iron lamellar armor, swords, bows, crossbows, spears, cavalry tack and wooden carts. Leave calm negative space for webpage copy. No baked-in text, readable banners, subtitles, logo or watermark; no clone-face armies, fantasy armor, Ming/Qing gear or architecture, imperial yellow dragon robes, Forbidden City, modern firearms, European plate, magic, anime, gore or body piles.

### 02｜夏军合围·断绝取水
|
||
|
||
- 时间地点：永乐城外与无定河通道
|
||
- 本幕作用：呈现围城通过控制水路削弱守军，而非神秘诅咒。
|
||
- 分幕旁白：西夏军占据城外高地和取水道路，击退宋军援兵。城中缺水，军马和守军迅速疲惫。
|
||
- 页面标题：最先失守的是水路
|
||
- 页面短句：城墙还没有破，水桶已经回不来了。
|
||
- PNG：`images/02-western-xia-cuts-water-to-yongle.png`
|
||
- WebP：`images/02-western-xia-cuts-water-to-yongle.webp`
|
||
- 替代文本：烈日下的永乐城外，西夏骑兵占据通往河谷的坡道，宋军运水队推着空桶和驮架退回城门；城头守军把最后几桶水分给军马，远处援军被阻在尘线之外。
|
||
- 视觉推演边界：道路控制、空桶、分水与援军距离为视觉转译；夏军围城、断取水并败宋援军有史载。
|
||
- 人物：西夏统军（梁氏政权前线将领；组织围城并控制无定河通道）；徐禧（永乐城守方主事；调兵守城并等待援军）；宋军运水队（役夫与护送军士；在敌军控制道路后被迫退回）
|
||
- 史料：《宋史·徐禧传》卷三百三十四；《宋史·夏国传》卷四百八十六

Use case: historical-scene. Digital Me Southern Song, Western Xia and Jin story frame. Under a harsh sun outside Yongle, Western Xia cavalry controls the slope toward the river while a Song water detail retreats with empty barrels and pack frames. At the gate, defenders ration the last visible buckets between soldiers and horses; a relief column remains blocked in distant dust. Show siege logistics and thirst without starving caricature, miraculous drought, giant army wall or violence. Premium live-action Chinese historical film still, archaeology-informed eleventh-to-thirteenth-century East Asia, cinematic 16:9 landscape, subtle film grain, physically plausible troops, cities, rivers, ships and logistics, packed earth, aged timber, hemp, low-sheen silk, leather, iron lamellar armor, swords, bows, crossbows, spears, cavalry tack and wooden carts. Leave calm negative space for webpage copy. No baked-in text, readable banners, subtitles, logo or watermark; no clone-face armies, fantasy armor, Ming/Qing gear or architecture, imperial yellow dragon robes, Forbidden City, modern firearms, European plate, magic, anime, gore or body piles.

### 03｜城陷人散·西北转守
|
||
|
||
- 时间地点：永乐城破口与宋军后方堡寨
|
||
- 本幕作用：交代城破、将领战死和宋廷战略受挫。
|
||
- 分幕旁白：永乐城在缺水和猛攻中陷落，徐禧等战死。败报传回后，宋廷重新评估深入西夏的筑城战略。
|
||
- 页面标题：一座新城没有撑过秋天
|
||
- 页面短句：地图上向前的一格，最后变成了后方每座堡寨都要重新计算的距离。
|
||
- PNG：`images/03-yongle-falls-and-frontier-reassesses.png`
|
||
- WebP：`images/03-yongle-falls-and-frontier-reassesses.webp`
|
||
- 替代文本：黄昏永乐城一段土墙坍塌，西夏军从缺口有序进入，宋军残部从另一侧护送伤员撤离；前景驿骑携无字败报奔向远处后方堡寨，堡寨官吏查看水桶和粮袋。
|
||
- 视觉推演边界：破口、双向队伍与后方复核为跨时段视觉压缩；永乐城陷、徐禧等死与宋廷受挫有史载。
|
||
- 人物：徐禧（宋给事中；城陷时战死；不展示遗体）；李舜举（宋内侍、监军；与守军共同战死；不展示死亡）；宋军残部与后方官吏（撤退者和边防经手者；携败报返回并复核粮水路线）

Use case: historical-scene. Digital Me Southern Song, Western Xia and Jin story frame. At dusk, one section of Yongle’s earthen wall has collapsed and Western Xia troops enter in controlled formation while Song survivors escort covered wounded people out along another route. In the foreground a courier with a blank defeat report rides toward a distant rear fort where officials inspect water barrels and grain. Use depth to connect defeat and policy reassessment; no citywide blaze, bodies, execution or triumphant slaughter. Premium live-action Chinese historical film still, archaeology-informed eleventh-to-thirteenth-century East Asia, cinematic 16:9 landscape, subtle film grain, physically plausible troops, cities, rivers, ships and logistics, packed earth, aged timber, hemp, low-sheen silk, leather, iron lamellar armor, swords, bows, crossbows, spears, cavalry tack and wooden carts.

## BGM 选曲
|
||
|
||
- 项目曲目：`zhanzhen:anshicheng#0`｜唐太宗征高句丽·安市城之战｜电影级配乐·筑城与补给失败结构借用·仅器乐 stem
|
||
- 状态：pending-export
|
||
- 用法：删除辽东、唐代人物动机与全部人声，只取夯土劳动、补给收紧和撤退弧线；城陷处不做英雄化爆燃。
|
||
- 选择理由：项目暂无永乐专曲，安市城曲能表现工程、补给和攻守受挫；需明确两战时代与地点完全不同。仓库暂无成品音频。
|
||
- 音频路径或 URL：仓库暂缺，待导出
|
||
|
||
| 时间 | 分幕 | 编排 |
|
||
|---|---|---|
|
||
| 00:00–00:28 | 01 | 夯土节奏与驮水铃声。 |
|
||
| 00:28–00:56 | 02 | 节拍收窄表现断水。 |
|
||
| 00:56–01:24 | 03 | 城破短峰后退为驿骑与风声。 |
