The most exposed towns fronting the New Hampshire line were Haverhill, Andover, and Dunstable. The _History of Haverhill_, by G. W. Chase (1861), gives the story of the Indian troubles with much detail.[453] For Andover they may be found in S. L. Bailey’s _Historical Sketches of Andover_ (Boston, 1880); and for Dunstable in Elias Nason’s _History of Dunstable_ (1877). Just below Dunstable lay Groton, and Dr. Samuel A. Green’s _Groton during the Indian Wars_ supplies the want here,—a good supplement to Butler’s _Groton_. The frontiers for a while were marked nearly along the same meridian by Lancaster, Marlborough, Brookfield, and Oxford. The _Early records of Lancaster, 1643-1725_, _edited by H. S. Nourse_ (Lancaster, 1884), furnishes us with a full reflection of border experiences during King William’s, Queen Anne’s, and Lovewell’s wars, and it may be supplemented by A. P. Marvin’s _History of Lancaster_. The sixth chapter of Charles Hudson’s _Marlborough_ (Boston, 1862), and Nathan Fiske’s _Historical Discourse on Brookfield and its distresses during the Indian Wars_ (Boston, 1776), illustrate the period. The struggle of the Huguenots to maintain themselves at Oxford against the Indians is told in Geo. F. Daniels’ _Huguenots in the Nipmuck Country_ (1880), and in C. W. Baird’s _Hist. of the Huguenot Emigration to America_ (1885). There is in the cabinet of the Mass. Hist. Soc. (_Misc. Papers_, 41.41) an early plan of the Connecticut and Housatonic valleys, showing the former from the sea as far north as Fort Massachusetts, and the latter up to Fort Dummer, and bearing annotations by Thomas Prince. [Illustration: BLOCK HOUSE, BUILT 1714.] In the valley of the Connecticut, Northfield held the northernmost post within the Massachusetts bounds as finally settled. One of the best of our local histories for the details of this barbaric warfare is Temple and Sheldon’s _History of Northfield_. Deerfield was just south, and it is a centre of interest. The attack which makes it famous came Feb. 29, 1704-5, and the narrative of the Rev. John Williams, who was taken captive to Canada, is the chief contemporary account. Gov. Dudley sent William Dudley to Quebec to effect the release of the prisoners, and among those who returned to Boston (Oct. 25, 1706) was Williams, who soon put to press his _Redeemed Captive_,[454] which was published in 1707,[455] and has been ever since a leading specimen of a class of books which is known among collectors as “Captivities.”
