Although several Colombians of varying prominence had suggested the possibility of an imminent Isthmian revolt, it seems that the events of and immediately after November 3, 1903, took most of their countrymen by surprise. Certainly there is no evidence of significant prior planning for such a contingency. The achievement of Panamanian independence was followed, in turn, by a Colombian failure to establish a consistent and coherent policy designed either to regain the lost province or to implement terms by which the loss could be made more acceptable. This is not to say that Colombians, officially and unofficially, did nothing in response to the Panamanian separatist movement. Yet what is impressive is not what happened, but what did not happen: There was no sustained military movement against the Isthmus, no break in diplomatic relations with the United States, no serious reprisals against Americans and Isthmians, or their property, in Colombia, and no vigorous protest against the incumbent Colombian political leadership. Panama was apparently not a major issue even during the Presidential campaign and election of 1904. The lack of preparation alluded to above was surely a factor in determining this limited response, but it was a small factor and offers, at best, an incomplete explanation. In fact, the mildness of the Colombian reaction was the product of the unique interaction of domestic and international, contemporary and historical conditions which this article seeks to illuminate.
