There is as much social history as military here, as Mr. Martin describes his inoculation with smallpox, his shock at being introduced to a white Connecticut farmwoman's black husband, and the ubiquity of alcohol.
One is struck, in Mr. Martin's account, by how seldom the British /Hessians and American/French ever bothered to shoot each other. There seems to have been a consciousness of the enemy as a human being which made shooting him difficult. This could be hindsight on Mr. Martin's part, but it does jibe with the fact that the total combat death toll for the war (excluding disease and starvation) was around 5,000 on both sides.
Mr. Martin himself seems to have spent much of the war starving. He was only paid twice-- once when he signed up in 1776, and once in 1781 by French officers who dipped into their own pockets to give him a month's salary. Nor was he ever paid anything after the war by a grateful nation. Then again, given that American troops were fed by commandeering groceries, liquor and livestock from local farms, much of the nation may not have been that grateful.
You might be, though, after reading this book. I was. And it's good to remember that fighting for our nation's freedom, once upon a time, meant fighting on our own land instead of other people's.
Martin campaigned almost continuously from the beginning of the War through Yorktown (with the exception of the first winter after his initial three month service). He lived much of what have become the hallowed tales of our epic struggle for nationhood. He was at the Battles of Brooklyn, Harlem Heights and White Plains, endured Valley Forge (though for most of that winter stationed away from the camp as a forager), Monmouth, the other terrible winter encampments and Yorktown to name a few. Through it all, Martin marched, froze, starved and suffered for his service. It is remarkable that he kept at it for most of the war. (One reads of the constant lack of food (often for two or days) and is amazed that more soldiers didn't simply just quit.) It is more remarkable that he kept at it in fairly good humor - though he did parade with the Connecticut troops who conducted a minor mutiny over the lack of provisions. (An incident that Washington reported to Congress as more worrisome to the cause than the British force occupying New York.)
Martin is a good storyteller and raconteur. The reader will not find detailed accounts of battle here. In fact, battle is mentioned rather matter-of-factly. What is delightful to find is an account of the day in and day out hardships of life in Washington's army. Stories abound of camp life, foraging, marching, guard duty, scrapes with Torries, the hunt for clothing and the other ever-present challenges that soldiers had to endure and perform to simply survive between battles.
This is a wonderful book that I highly recommend.
