Both Burke and Coxe have said that Jenkins never lost his ear from the stroke of a Spanish ‘cutlash’; a modern historian has shown it to be likely that he did. What, however, is more important than the establishment of this truth is the decision as to the exact amount of influence it had upon producing the war which followed. Jenkins' ear may be said to typify the feelings of the English public in their broad sense, their hatred for the Spaniards as cruel Papists, their insular detestation of the foreigner, and the like. The question is how far did these feelings influence the declaration of war; what were the main motives of the diplomats on either side? Did the English statesmen first truckle to Spain and then to England? The great interest of such an inquiry lies in the fact that the year 1739 was a turning point of history. It was, perhaps, the first of English wars in which the trade interest absolutely predominated, in which the war was waged solely for balance of trade rather than for balance of power. But it is not alone memorable on this account; from this war issued, in a clear and undeviating succession, the series of wars which were waged between England and France during the eighteenth century — wars in which Spain was sometimes a passive spectator, oftener an active enemy, never the friend of England. Spain's alliance with France produced grave complications for England in 1743, contributed to the fall of the greatest of English ministers in 1761, and to the loss of the greatest of English colonies in 1783.
