Riga (Thirty Years' War).

This place was invested by the Swedes, under Gustavus Adolphus, in the early part of August, 1621, and was defended by a garrison of 300 Poles. A resolute defence was made, and several determined assaults repulsed, but a large breach having having been effected by September 11, the garrison, now reduced to a handful, had no option but to surrender, and the town was entered by the Swedes, September 15, 1621.
