Where Roskill fits in interwar reading

How should a reader approach Roskill's naval-policy volumes?

They are worthwhile but demanding and should be read with awareness of an official historian's emphases; broad treaty-era surveys are a better starting point.

Roskill's work is useful but heavy going. As an official historian and Royal Navy captain, he can emphasize some people and ships while leaving other matters less prominent, even when his statements are technically accurate. The Jordan treaty-era books provide a more accessible overview of the interwar naval world. Roskill then works better as a deeper, British-focused study.
