Brook and its surrounding villages had their fair share of highs and lows during the two world wars.

A stained glass memorial window in Brook Church gives the names of those people from Brook and the neighbouring parishes who served and those who died.

In both World Wars, Brook people of military age went into the services unless they were in reserved occupations. But the village remained for the most part a peaceful place. Occasionally areoplanes came very close, and one or two actually came down. It was a worrying time for all.
