1258年，10月20日，海州，郁州岛。
郁州岛面积不小，但中央高耸的云台山占据了绝大部分，只在西岸有少量的平地。这一点平地又被两道“八”字形分布的山岭包裹了起来，一座依山而建的小城矗立其中。此城正对海岸的西墙是一整堵高大封闭的城墙，并未开门，进出只能走南北两侧的小门，门西侧还增建了凸出的马面，可谓易守难攻之至。
此城就是东海县城，是宝祐二年（1254）由两淮制置使贾似道主持修建的，用于防备大陆方向的蒙军袭击，并作为反攻作业的基地。实际上，它也确实发挥了这个作用。
不过现在，城对面狭窄的海峡中已经布满了密密麻麻的小型桨帆战船，南北两道山岭前方的哨塔也被占领，换上了“姜”字旗帜。
海对面海州一侧的大营中，姜思明站在望楼上，看见己方的水军已经占据了水道并控制了滩头阵地，得意地大手一挥道：“开始渡海，今晚就在对岸扎营！”
这不是蒙古势力第一次攻打郁州岛了，但以往这里的宋军有水军优势，又有淮河一线的宋军牵制，所以很难攻上岛去。而此次情况就完全不一样了，涟水和黄河入海口已经被李璮攻占，黄淮一线的宋军无法对此地进行支援，同时北风已起，长江附近的宋军也远水解不了近渴，城中守军只能困守孤城了。
而且前不久东海县的宋军主动向海州出击，消耗了大量补给却无功而返，最后撤退的时候损失了不少兵力和船只，可以说伤了元气。而姜家军的实力一直保存得很好，还得到了在涟水缴获的大量战船支援。此消彼长之下，姜思明的进攻行动就顺利了很多。
他先是令海州留守的千夫长赵咎率军佯作渡海，引出宋军水军后，再令周围埋伏的己方水军袭击。虽说李璮系水军的战斗力比宋军要差些，但架不住数量多，宋军很快不敌，被迫退入港中。
占据了水上优势后，登陆行动就很顺利了。海州海峡本来就只有几里宽，先头部队很快就通过渡船到达了郁州岛，这点距离也不至于晕船，登陆之后顺利占领了宋军在海边设置的几个哨塔。
宋军此时在东海县的兵力不足三千人，还分布在各个岛上，被姜思明的水军分割开来，无力夺回滩头阵地，只能在东海城中准备防御武器，以待固守。
……
10月21日，凌晨时分，东海城中。
东门内侧，近百名披挂完毕的士卒排成行，站立在城墙根附近。海州通判侯畐带着十几个跳着担的夫子，挨个给他们发了一小块银子，还有两个热腾腾的肉馅炊饼和一小瓶黄酒，同时还小声叮嘱着他们什么。
拿到东西的士卒也不吭声，直接坐在地上，把银子塞进怀里，然后三下五除二把炊饼吞了下去，又仰头把酒灌进肚子里。
侯畐走到城门边上，对着队伍中领头的一个军官说道：“孙队正，这次袭营关系重大，就交给你了。”请求出错，状态码:502内容:<!DOCTYPE html>
