Antanas Mackevičius (; 26 June 1828 – 28 December 1863) was a Lithuanian Roman Catholic priest who was one of the leaders and initiators of the January Uprising in Lithuania.

Mackevičius was born to a family of petty nobles. He studied in Kyiv and Varniai. He became involved in the uprising conspiracy. After the outbreak of the January Uprising in Warsaw on January 22, he announced the manifesto of the National Government on March 8 and formed a unit in Paberžė, which consisted mainly of the local Lithuanian peasants that enthusiastically joined his units. Mackevičius, dressed in the priest's Cassock coat himself, being bi-lingual, commanded his troops in the Lithuanian and Polish language. He joined Zygmunt Sierakowski's unit, after whose defeat he continued to fight on his own. He was one of the longest-fighting commanders of a partisan unit in Lithuania. On 17 December 1863, he was captured by the Russians and executed a few days later in Kaunas. He became a legend during his lifetime and is still considered a national hero in Lithuania and Poland.

Early life and education Mackevičius was born on 26 June 1828 in Morkiai village, near Tytuvėnai in Raseiniai County. At the time, this was in Lioliai parish. His parents were the petty nobles Tadas Mackevičius (Tadeusz Mackiewicz) and Marijona Mackevičienė. In 1840, at the age of 12, Mackevičius walked by foot to Vilnius in order to pursue education. He spent six years learning in the Vilnius Gymnasium. This gymnasium was located in the former Vilnius University, which was closed after the failed 1831 Uprising. It's not clear whether Mackevičius finished his secondary education. After that Mackevičius studied at the then-renowned Saint Vladimir University in Kyiv from 1846 to 1849. However, he did not finish studies, because he firmly resolved to becoming a priest. He did so because he thought that this would bring him closer to the common Lithuanian people. Thereafter, from 1850 to 1853, he was in the Varniai Priest Seminary.

Catholic Ministry He was ordained, and between 1853 and 1855 he served as the vicar in Krekenava. Then, between 1855 and 1863, served as a priest in the Paberžė church, which was a part of Surviliškis parish. Mackevičius had close relations with the local peasants and was liked by them. During his ministry in this parish he organised patriotic demonstrations. In 1861, he delivered an anti-government sermon in Lithuanian on the anniversary of the Union of Lublin. These had to end after the introduction of martial law in Lithuania in 1861. At that time Mackevičius became involved in secret circles and joined the Reds' party. He himself founded two in Surviliškis and Paberžė. The priest Vincentas Šliogeris conducted similar activities in the neighbouring Vilkija and Šventybrastis. The circles were subordinated to the movement's committee in Kaunas, and later in Vilnius. Everything was supervised by Zygmunt Sierakowski from Saint Petersburg. Bolesław Dłuski was closely collaborating with Mackevičius. In the summer of 1862, Father Mackevičius attended the wedding of Zygmunt Sierakowski and Apolonia Dalewska. Most of the later leaders of the Lithuanian conspiracy gathered at the ceremony. Couple of days before he was nominated a representative of the (Komitet Prowincjonalny Litewski) of the Reds for Samogitia. This was the start of feverish preparations for the uprising. Father Mackevičius was gathering weapons, supported by Józef Mickiewicz, Bolesław Dłuski and peasant Adomas Bitė.

1863―1864 Uprising

Prelude When the uprising finally started in Warsaw on 22 and 23 January, the preparation in Lithuania accelerated even more. Because of the lack of arms and money Lithuanian Provincial Committee decided to postpone the start of the uprising for a couple of weeks and to limit it to only Vilnius, Kaunas and Grodno governorates. The committee was soon transformed into the Administrative Department of the Provinces of Lithuania (), where the authorities were held by the Whites, headed by . The new insurrectionary government ordered to refrain from overt demonstrations until the end of April. Neither Antanas Mackevičius nor Bolesław Dłuski heeded the call to not join the uprising.

Spring

Mackevičius ordered the priests of Liauda and Samogitia to read the National Government's manifesto and its decrees. He himself did it on 8 March 1863, when he read the manifesto during a sermon at the church in Paberžė () and Surviliškis. He called upon the people to rise up and restore independence, and promised to reorganize society by granting greater rights and land to peasants. Mackevičius succeeded in organizing some 250 men, armed with hunting rifles and straightened scythes, into the Paberžė Regiment, and soon the unit grew to 500 men. The unit was mainly made up of local peasants, but there were also representatives of the gentry, mainly the poor, urban youth and students. Germans, Prussian Lithuanians and volunteers from Mazovia also joined the unit. The officers were mainly fugitives from the Russian army, as well as cadets from the Polish military school in Cuneo. Unit was soon joined by Bolesław Kołyszko as a military instructor. His unit used a banner sewn from two parts: the top navy blue and the bottom crimson. It depicted on the main side the White Eagle wearing a crown and the inscription in Polish: PUŁK PODBRZEŹSKI (the Paberžė Regiment), and motto in Polish: BOŻE ZBAW POLSKĘ (God, Save Poland). On the other side was an oil painted image of the Virgin Mary and St. Elisabeth. The insurgents wore gray knee-length sukmanas girdled with a leather belt, and the officers wore czamaras. On their heads, they wore rogatywka-style hats trimmed with sheep fur (so called krakuska). The first rebel marches were akin to celebratory processions. Wherever Mackevičius and his soldiers entered, he was joyously received. Wherever he went, Mackevičius was greeted with crosses, flags, hymns, and with bread and salt. The priests organised celebrations, sang Te Deum in the churches and read the rebel's manifesto from their pulpits about freeing the fatherland and giving land to the peasants.

Later his unit merged with Bolesław Dłuski's party and on March 27 both units defeated a larger Russian unit near Miegėnai. On March 27, the units led by Mackevičius fought against four Russian infantry companies and one cavalry squadron near Naujaberžė. After the fight both divisions separated. Dłuski went towards the forests of Krakės, where he joined major Tomasz Kuszłejko's unit. Mackevičius together with 120 men went towards Kaunas. On April 19, he joined forces with the joint rebel army led by Zygmunt Sierakowski. Both soon clashed with Russians on 21 April during the victorious battle of Genėtiniai. Mackevičius' scythemen distinguished themselves in the battle of the Raguva forests on April 21. On April 26, Mackevičius fought in the battle of , located in the forests of Karpis and Komaras, in the Panevėžys County. After this battle, several commanders active in the area joined forces under Sierakowski's command. According to Puzinas, Mackevičius was appointed commander of the 4th battalion, while according to Kozłowski, he was the 3rd battalion's commander. Soon, it was detached by Sierakowski for special tasks — destroying archives, taking over county coffers and others. On May 3, Mackevičius group was near Kamajai, while the next day, a part of his group was in Rokiškis. At the time, Sierakowski began marching towards Dünaburg in Courland and Mackevičius commanded the right-wing. Because of that, he took part only in the battle of , i.e. the last part of the three-days long battle of Biržai, during which Sierakowski's brigade was defeated and destroyed. After the failed battle on May 8/9 near Gudiškiai, where Sierakowski was wounded and captured, Mackevičius' unit went from the Panevėžys County to the Raseiniai County.

After the battle, Mackevičius gathered about 400 men and moved towards Panevėžys. On his way, he met the unit of , who was appointed as commander by wounded Sierakowski. They joined forces and created a strong unit of about 1000 partisans, which was on 16 May strengthened by Mamert Giedgowd' soldiers, near Paberžė. Soon Giedgowd disengaged and Mackevičius's and Laskowski's detachment headed for Tauragė to capture weapons.

Summer Throughout summer and autumn of 1863, Mackevičius fought many battles against the Russian Army, e.g. near Tytuvėnai, Šilalė, Rietavas, Tverai, Šiluva, Krakės, Josvainiai and others.

The detachment was constantly under attack, and on 2 June a major battle took place at Užventis. Reinforced by Jan Staniewicz's troop, the insurgents had the advantage and forced the Russians to retreat. The battle of Tytuvėnai on 6 June was similarly successful. Staniewicz then broke off, and Mackevičius and Laskowski marched further south. They successfully clashed with the Russian army at Žaiginys (19 June) and Konopajcice (22 June), but at (24 June) their unit was broken up.

Priest Mackevičius set off in the direction of Panevėžys, and on the way joined up with the Kończa party, but they soon separated. On 19 July, near Panevėžys, he tried to break up a Russian convoy - unsuccessfully, but he succeeded in a night attack on the Russian guard. There was also a successful skirmish near Bistrampolis Manor on the night of 31 July/1 August. The next major skirmish of Mackevičius's unit was the victorious battle of Kėdainiai on August 12. In the next battle, at Buda on August 20, the Russians had a six-fold advantage over the 120 partisans and, despite fierce defence, forced them to retreat. At the end of August, Konstanty Kalinowski, extraordinary commissioner of the National Government for Lithuania, appointed Mackevičius political commissar of the Kaunas voivodeship, and Ignacy Laskowski head of the Kaunas voivodeship.

Autumn

This did not change much, Mackevičius continued his guerrilla fight in the forests of Panevėžys. The only major skirmish in this period was the successful battle of Krekenava on 9 September. On October 9 Mackevičius's unit attacked a Russian unit on the route of the march from Kėdainiai to Ramygala. He then joined forces with the troops of Paweł Staniewicz near Šventybrastis. However, the grouping was attacked and broken up by the Russians on 19 October. On November 3 Mackevičius succeeded in breaking up a Russian detachment near Kėdainiai and captured a considerable amount of ammunition. Nonetheless, the uprising in Samogitia was collapsing. The troops that were still active gathered in the forests near ; besides Mackevičius, these were the parties of Aleksander Domaszewicz, Jurewicz and Jagiełłowicz. A total of 272 partisans. Mackevičius' last battle was on November 26 at near Vilkija. In this battle, the partisans were attacked and smashed by a 700-strong Russian detachment and the commander Aleksander Domaszewicz was captured.

After the battle, Antanas Mackevičius announced his departure and his intention to go to France to acquire firearms and start fighting again in the spring of 1864. According to other sources he was sent to Warsaw, in order to obtain information about the state of the uprising and to acquire weapons. Nonetheless, on December 17, he was captured near Ringuva, 5 kilometers from Vilkija, while preparing to cross the river Nemunas. He was captured together with Julian Rodowicz and his aide-de-camp Florjan D'Artuzi. Three of them were taken to the prison in Kaunas. After Mackevičius was captured, he was transported and shown throughout the country by the occupying Russian authorities to convince Lithuanians that further resistance was pointless. The Russians told Mackevičius that he would not be punished if he betrayed the other leaders of the uprising, but Mackevičius sternly refused. During interrogation and court proceedings, Mackevičius behaved admirably.
