Gazetted into the 9th Foot as an ensign in 1808, Peter Le Mesurier saw action from the earliest days of the Peninsular War almost to its end. The ëFighting Ninthí were in the thick of it, and his letters describe nearly every major engagement of the war; the retreat to Corunna, the Walcheren Expedition, the sieges of Ciudad Rodrigo, Badajoz, Burgos and San Sebastian, and the battles of Salamanca, Vitoria, the Nivelle and the Nive.??The correspondence of this young officer provides a unique and fresh insight into the campaigns of Moore and Wellington against Napoleon. They also show the transformation of the boy into the man. He suffers retreats and celebrates victories, witnesses sieges, rape and plunder, and falls in love; his letters are spiced with fascinating asides, wry humour, rich period detail, some very human fears and admissions, and the casual understatement of the British officer.??Any unpublished letters from the conflict are scarce, but such an extensive unpublished collection is rare indeed. With background information and commentary provided by expert Adrian Greenwood and meticulously footnoted, this is a worthy addition to the literature of the Napoleonic Wars.
