“ In the Thirty Years’ War, in June 1641, the Swedes, under Wrangel and Königsmark, defeated the Austrians under the archduke Leopold at Wolfcnbüttel. The town passed wholly into the possession of the Brunswick-Wolfenbüttel family in 1671, and for nearly one hundred years enjoyed the distinction of being the ducal capital. In 1754, however, Duke Charles transferred the ducal residence to Brunswick. ”
