In the summer of 1640, an event took place that would forever change the boundaries of the Connecticut River Valley. During a grain famine, the founder of Springfield, William Pynchon, was given authority by Windsor and Hartford to negotiate a price for grain for the three settlements with the natives. First, the natives refused to sell grain at the usual market price, and then refused to sell it at "a reasonable price". Pynchon refused to buy it, attempting to teach the natives a peaceful lesson about integrity and reliability. Windsor's cattle were starving, however, and the citizens of Hartford were furious. With Windsor's consent, Hartford commissioned the famous Indian fighter John Mason to travel to Springfield with "money in one hand and a sword in the other" to threaten the natives, and thereby force the grain trade. The natives capitulated and ultimately sold their grain. After "negotiating the trade", Mason refused to share the grain with Springfield, and, to add further insult, insisted that Springfield pay a tax when sailing ships passed Windsor. Outraged, Springfield forever sided with the Massachusetts Bay Colony, a faraway theocracy based in Boston, rather than with the Connecticut Colony, which was much closer geographically and far more compatible ideologically. Windsor played a neutral role in the colonial rivalry between Hartford and Springfield; however, Windsor's direct border with both settlements caused many discussions about whether to align with Massachusetts or Connecticut. Ultimately, Windsor sided with Connecticut.
