“Other Theatre” enthusiasts may be interested in images of forts at Przemysl, Poland that I visited earlier this month.
Przemysl was a communications hub and strategic location in the centre of the former Austro-Hungarian Province of Galicia.
The Austrians started constructing rings of forts around Przemysl in the 1850s.
Initially massive earthworks were constructed with open gun positions, but as artillery technology advanced military architects had to introduce concrete protection for some gun positions.
By August 1914 a large ring fortress had been constructed as shown on the map above.
The Austrians had garrisoned the fortress with around 60,000 men but had not provisioned it to include a similar number of men who withdrew from Eastern Galicia in the early days of the war and entered the fortress.
The defensive artillery was good, but for budgetary reasons not all guns had been provided with concrete emplacements or steel cupolas.
In early October 1914 a Russian army surrounded and attacked the fortress, losing many men in impetuous assaults. The Russians then withdrew in the face of a German-Austrian advance on Warsaw.
But in early November 1914 a Russian siege army besieged Przemysl again and began to successfully starve the garrison into surrender.
On 22 March 1916 the Austrian Fortress Commander, out of rations, ordered the blowing-up of all forts and guns and Przemysl surrendered.
The Russians held the fortress until early June 1916 when German and Austro-Hungarian troops recaptured Przemysl. After that date the fortress did not feature in the war.
