General Pershing's advance has met with very little opposition, but
to penetrate four hundred miles into so difficult a country snot a safe proceeding unless the troops guarding the lines of com- manication are numerous and well supplied. That the force with General Pershing, in spite of its small size, is an exceedingly com- petent one for its job we do not doubt, and we are sure that the General and his gallant men will in any case uphold the noblest traditions of the United States Army. If, however, it should be necessary for him to retire, General Pershing is sure to be exposed to -the difficulties which always arise when such a movement has te be carried out in the face of swarms of mounted guerrillas. Attacking a retiring enemy and raiding long lines of communi- cations are operations in which of all others they delight.
