Without which 定语从句

你把 without 之前部分看懂，后面就简单。看懂了？

I alone was able to write them down since I alone was privy to the very last details without which it would have been quite impossible to piece together a full and satisfying account.
我一个人就可以把它们写下来，因为唯独有我对这些细节了解。没有了这些细节(without which)，我是不可能把这个故事完整的，令人满意的叙述下来的。
