The last war but between Britain and Spain sprang from the attempts of the British merchants to prosecute an illicit trade with the Spanish main. These unjustifiable practices on their part produced severity on the part of the Spaniards toward the subjects of Great Britain which were not more justifiable, because they exceeded the bounds of a just retaliation and were chargeable with inhumanity and cruelty. Many of the English who were taken on the Spanish coast were sent to dig in the mines of Potosi; and by the usual progress of a spirit of resentment, the innocent were, after a while, confounded with the guilty in indiscriminate punishment. The complaints of the merchants kindled a violent flame throughout the nation, which soon after broke out in the House of Commons, and was communicated from that body to the ministry. Letters of reprisal were granted, and a war ensued, which in its consequences overthrew all the alliances that but twenty years before had been formed with sanguine expectations of the most beneficial fruits.
