[3] When Slovakia declared independence as a satellite of Nazi Germany, Žingor joined the fascist militia Hlinka Guard.

[1] Žingor fought with the Slovak army in the short Slovak–Hungarian War in 1939 and in 1941 on the Eastern Front near the Ukrainian city of Lypovets as an artillery commander.

The cooling of relations was largely caused by the incident when partisans under the command of Velichko raided Sklabiňa and massacred over 140 locals suspected of being of German nationality of otherwise supporting the regime.

[3] Among the new fighters was number of French captives who formed a unit under the Brigade under the command of captain Georges Barazer de Lannurien.

At the same time, Žingor's relationship with Velichko reached a critical point, in particular due to the Soviet commander's brutal methods and tolerance for looting.

The Brigade fought valiantly, being the only partisan grouping capable of holding ground against German forces without the assistance from insurgent units from the regular army.

Following the defeat of the Uprising, the remains of the brigade, consisting of about 300 men, retreated to the mountains and limited its activities to defensive operations due to the critical shortage of equipment.

[2] After the end of the war, Žingor was awarded the Order of the Slovak National Uprising, 1st class and repeatedly promoted eventually reaching the rank of Mayor.

Until 1947 he also served as the deputy commander of the newly formed police force, Sbor národní bezpečnosti, for Central Slovakia and the chair of the Union of Slovak Partisans.

He was politically upset by sidelining of former partisans at the expense of various well-connected individuals, who were unknown to the resistance movement during the war but suddenly claimed they had played crucial role in the anti-fascist struggle.

The Ministry of Justice published a pamphlet Red Hemingway written by Ladislav Mňačko, a fellow partisan, in which he accused Žingor of being a traitor to the Slovak National Uprising.

He stood accused alongside about 30 other "capitalists, landlords and traitors", including two other commanders of the 2nd Czechoslovak Brigade, Samuel Bibza and Ladislav Nosák, who also received death sentences.

Only after the return to democracy following the Velvet Revolution was Žingor fully rehabilitated, posthumously promoted to the rank of Brigadier General by the president Václav Havel and awarded the Milan Rastislav Stefanik Order, 3rd class.
