Foreign Aid.
A gentleman who rode over the battle-field near Gen. Magrader's headquarters, on the 18th of July, informs us that he counted in the field, prior to reaching the woods, 237 dead Yankees, and there was but one of the number that was not born in Europe. The only native Yankee was Col. Woodbury, of a Michigan regiment, who fell shot through the head. An attempt had been made to carry off the body, but the pursuit on our part becoming too hot, the custodians of the body dropped it and fled. Woodbury was a lawyer, and a man of considerable note in his section prior to the war.
