As
voivode of Kiev, Chodkiewicz defended the region from Tatar invasion. In 1558, he achieved a victory in
Podolia against the
Crimean Khanate. This victory raised prestige of Chodkiewicz as a military commander. On the onset of the
Livonian War, he was promoted to
castellan of Trakai with intention to use his skill in the war. In 1561, Grand Hetman
Mikołaj Radziwiłł the Black, Chodkiewicz, and his brother
Hieronim led the
Grand Ducal Lithuanian Army into
Livonia where they achieved victory against the
Tsardom of Russia. After this campaign, Chodkiewicz was promoted to
Field Lithuanian Hetman. On 20 January 1564 the Lithuanians under his command killed Russian commander
Shuisky and defeated the Russian army in the
Battle of Ula, which significantly improved Lithuania's standing in the war. He was hailed as war hero and promoted to
castellan of Vilnius. Royal favor continued: Hrehory's nephew
Jan Hieronimowicz received his late father's position as
Elder of Samogitia in 1564, brother
Yurii, who traveled to Moscow for diplomatic negotiations, became castellan of Trakai and Hrehory was appointed
Grand Hetman of Lithuania in 1566. Thus, Hrehory Chodkiewicz became the second man after
Mikołaj Radziwiłł the Red and the Chodkiewiczs controlled three out of five top seats in the
Lithuanian Council of Lords. In 1567, Chodkiewicz achieved another victory in Livonia, this time against the
Kingdom of Sweden. ==Cultural activities==
