This is an enjoyable and well written account of the 1914 truce that happened during World War 1 on the Western Front in the improbable setting of the trenches. Time and again Stanley Weintraub uncovers examples of how, despite orders from senior officers, the troops in the trenches came together to sing carols, exchange gifts, eat and drink together, and even play football. In most of these examples the troops discovered how alike they were and how much they shared in common.
I am not sure this subject warrants a whole book and there is quite a bit of repetition as Stanley Weintraub gives numerous different examples of the different ways the truce occurred in different parts of the Western Front.
The book concludes with a short chapter titled "What if....?" in which Stanley Weintraub speculates what might have happened had the war ended with the 1914 Christmas truce which felt a bit pointless.
Interesting, if inessential.
