THE lens here perpetuates the interesting spectacle of an army wagon train being "parked" and guarded from a raid by the enemy's cavalry. With a million of the nation's strongest men abandoning production to wage devastation and destruction the problem of providing them with food barely sufficient to sustain life was an almost incalculable enigma. The able-bodied men of the North and the South had turned from the fields and factories to maintain what both conscientiously believed to be their rights. Harvests were left to the elements and the wheels of industry fell into silence. The good women and children at home, aided by men willing but unable to meet the hardships and exposures of warfare, worked heroically to hold their families together and to send to their dear ones at the battle-front whatever comforts came within their humble power. The supply trains of the great armies numbered thousands of six-mule teams and when on the march they would stretch out for many miles. It was in May, in 1863, that one of these wagon trains safely reached Brandy Station, Virginia. Its journey had been one of imminent danger as both armies were in dire need of provisions and the capture of a wagon train was as good fortune as victory in a skirmish. To protect this train from a desperate dash of the Confederate cavalry it was "parked" on the outskirts of a forest that protected it from envious eyes and guarded by the Union lines. One of Mr. Brady's cameras took this photograph during this critical moment. It shows but one division of one corps. As there were three divisions in each corps, and there were many corps in the army, some idea of the immense size of the trains may be gained by this view. The train succeeded in reaching its destination at a time of much need.
