Greater Lithuania fought war on two fronts east and west. Rex Algirdas Lithuaniae ordered to take Moscow 3 times and Lithuanian army with rapid force marches besieged Moscow in 1368 and 1370. In 1372 a large Lithuanian army this time supported with siege equipment was gathered to finally take Moscow, however Muscovites received support as Mongol tributaries and both large armies decided to stand down. Rex Algirdas Lithuaniae turned around most of his army to counter Western Europe's invasions of Lithuania Proper in the West. Notable example is King of England Henry IV personally coming to help siege Vilnius. Western European armies were driven out from Lithuania's capital, however with such dedication and sheer resources occupied Western Samogitia which Vytautas Alaxander the Great will recover.
