标 题: 历史上死难最多的一次海难事故死了九千多人
发信站: BBS 未名空间站 (Wed Jun 3 00:15:55 2015, 美东)
威廉·古斯特洛夫号（德语：Wilhelm Gustloff）是一艘纳粹德国邮轮，由布罗姆与沃
斯船坞（Blohm + Voss）所建造，她的名字是来自纳粹党瑞士分部的领袖威廉·古斯特
洛夫，于1937年5月5日下水。在二战末期，此船用来载运遭苏联红军围困在东普鲁士的
德国人（包括平民及少数官兵），最后在1945年1月30日于波罗的海被苏军潜艇发射三
枚鱼雷击沉。遇难人数估计由5,300至9,931人不等[1][2]，是泰坦尼克号的六倍有多，
成为历史上遇难人数最多的海难。凑巧的是，当天正是威廉·古斯特洛夫50岁冥寿，也
是希特勒上台的12周年。
威廉·古斯特洛夫号最后的任务是由格丁尼亚撤离德国平民、伤兵及海员经波罗的海返
回德国基尔（Kiel）港，船上已登记的海员及乘客总数是6,050人，但这数字并未计算
没有纪录的数千名难... 阅读全帖 |

This issue is more about national interests, not China-bashing... (Of
