In 1674, George was a candidate for the Polish elective throne, for which he was backed by King Louis XIV of France. George's staunch Lutheranism was a barrier to election in Roman Catholic Poland, and John Sobieski was chosen instead. In 1677, George served with distinction with his elder brother Christian in the Scanian War against Sweden. His brother was captured by the Swedes at the Battle of Landskrona, and George "cut his way through the enemies' numbers, and rescued him at the imminent danger of his own life."
