The Battle of Sellenberk was a World War I military engagement fought between Romanian forces on one side and Central Powers forces (Austria-Hungary and Germany) on the other side. It was part of the wider Battle of Transylvania and resulted in a Romanian victory.

Background

Main article: Nagyszeben Offensive

On 27 August 1916, Romania declared war on Austria-Hungary and proceeded to invade the Hungarian region of Transylvania. The Romanian campaign plan called for the Olt-Lotru Group of the Romanian 1st Army under the command of General Ioan Culcer to secure the basin between Nagytalmács (Tălmaciu/Talmesch) and Nagyszeben (Sibiu/Hermannstadt). The area between Nagyszeben and the northern exit of the Turnu Roșu Pass was the designated assembly area for the 1st Army's Olt-Lotru Group. Opposing the Romanian invasion of Transylvania was the Austro-Hungarian 1st Army under the command of General Arthur Arz von Straussenburg. ^[1] Nagyszeben (Sibiu/Hermannstadt) was occupied on 2 September by advanced troops of the Romanian 1st Army. However, the Romanians evacuated the city on the following day. ^[2] Erich Ludendorff referred to this in his memoirs, stating that, after taking Brassó (Brașov/Kronstadt) on 29 August, "Rumanian patrols were soon seen in Hermannstadt.". ^[3] The Romanians were plainly apprehensive that, in order to keep Nagyszeben under occupation, they would have to extend their bridgehead-like formation beyond capacity. ^[4]

The Romanian forces in the region consisted of the 1st Army's Olt-Lotru Group (2 divisions), which was placed by General Culcer under the command of General Constantin Manolescu  [ ro ]. Opposing the Romanians was the 51st Honvéd Division (commanded by General Béla Tanárky  [ ro ]) of the Austro-Hungarian 1st Army. ^{[5] [6]}

Battle

The battle for Sellenberk (Șelimbăr/Schellenberg) started on 7 September. ^[6] However, on 8 September, following the German-Bulgarian victory at the Battle of Turtucaia in Southern Dobruja, the Romanian High Command ordered a halt to the Transylvania offensive. ^{[7] [8]} Also on 8 September, the XXXIX Corps of German General Hermann von Staabs assumed responsibility for operations in southern Transylvania. ^[9] One of the units placed under the command of von Staabs was the 51st Honvéd Division. ^[4] The battle was resumed on 10 September. ^[6] That same day, the Romanian 1st Army entered Sellenberk. ^{[10] [11]}

Aftermath

Main article: Veresmart Offensive

On 10 September, the Romanian 1st Army captured Sellenberk (Șelimbăr/Schellenberg), two miles southeast of Nagyszeben. This marked the end of the Romanian advance in the area for the ensuing fortnight. ^{[12] [11]} Sellenberk — where Michael the Brave had defeated the Hungarians in 1599 — became the center of the main Romanian position north of the Turnu Roșu Pass. ^{[13] [14]}
