The Pen Is Feebler Than The Sword

I WAS excited to receive through the post from military books specialists Pen & Sword their spring catalogue.

Pen & Sword's catalogue

But my pleasure soon turned to frustration at the contents:

In WWI, Scandinavian countries proclaimed their neutrality but pitched the two warring sides against each other to protect their trades. [No they didn't!]

Using veterans own words ... [Missing apostrophe]

The Author sets the scene ... [Why Author rather than author?]

A Wargamer's [sic] Guide to the Early Roman Empire ... the dramatic events of the Norman conquest.

This is a unique and original material.

In 73 AD [AD stands for anno domino, the year of our Lord, so correct is AD 73]

This is the story of how the company began, how it grew, and how they diversified ... [Why switch from singular to plural?]

My point, and I have only looked at bits I thought might particularly interest me, is that I very much hope the catalogue is not typical of the care exercised at Pen & Sword.
