Blockade of Pernau, 1710
Блокада Пернова, 1710
(Книга марсова. СПб. 1766), 

Swedish garrison of Pernau consisted of 2 foot regiments & a small detachment of recruits of Nyland regiment in 1710. Both regiments had authorized strength of about 800 men each, but their exact strength is unknown. They heavily suffered from disease, a lack of supplies & desertion in winter-spring of 1710. Captives estimated total garrison's strength around 1,000 men at the start of the siege. Commandant was colonel Jakob Henrik von Schwengelm.
Regiments of Pernau garrison in 1710:

• Livland varvade regiment under colonel Magnus Wilhelm Nieroth composed of 16 coys (50 men each): overste (colonel's Lifkompaniet), overste-lojtnant Nikolaus von Vettern, major Fredrik Wilhelm von Holden, kaptens Karl Gustaf von Treiden, Karl Gustaf Taube, Henrik Johan von Essen, otto Gustaf Douglas, Justus Mensenkampff, Andreas Johan Kallmann, Adrian von Holden, Georg Gotlieb Schweb, Karl Gustaf von Nothafft, Jakob Gustaf von Bellingshausen, Samuel Benisch, Joakim Johan Muhlenbeck, Karl Ludolf von Vettern.
• Livland varvade regiment under colonel Jakob Henrik von Schwengelm composed of 10 coys (75 men each): overste (colonel's Lifkompaniet), overste-lojtnant Magnus Fredrik Wolffelt, major Fabian Gustaf Aderkas, kaptens Fromhold Berg, Fredrik Kaspar von Schilling, Wolmar Otto von Derfelden, Tomas Gahrenfelt, Valentin Rommeling, Hans Henrik Wehber, Karl Johan Ekeskold.  

Pernau was blockaded on 22 July 1710 by a Russian Corps under GL Bauer. It consisted of 6 Dragoon regiments: Kiev, Viatka, Troitckiy, Novotroitskiy, Yamburg, Neva. By that moment Riga had capitulated, & Swedish officers & soldiers of Livland-origin didn't have any reasons for a serious resistance. They sent a delegation to Bauer asking him to let them go to their estates. Bauer refused. He insisted on a capitulation of the Pernau garrison.
On 8 August Schwengelm himself came to Bauer to ask him to let Livland officers go off from Pernau. Bauer again refused & told that he was waiting for a siege artillery to start bombardment. It forced Swedes finally agreed to capitulate on the terms of free passage on 14 August of 1710.
Pernau garrison heavily suffered during the blockade & numbered only about 120-150 men on 15 August of 1710. The most of troopers entered Russian service.

Блокада и капитуляция Пернова, 22 июля - 15 августа 1710.

Relation about taking of Pernau
Реляция о взятии Пернова
(Книга марсова. СПб. 1766)

Гарнизон Пернова состоял из 2 пехотных полков, каждый по штату по 800 чел. (см детали по их организации в ангоязычной части поста) и команды рекрутов Нбландского полка. Их реальная численность на момент осады неизвестна, по словам пленных - около 1 тыс. чел. Артиллерия насчитывала 183 пушки, 14 мортир и 4 гаубицы.
27 июня из-под Риги для блокады Пернова был отправлен отряд г-п Боура в составе 6 (Киевский, Вятский, Троицкий, Новотроицкий, Ямбургский и Невский) драгунских полков. По неясной причине путь до Пернова у него занял почти месяц, и он прибыл к городу лишь 22 июля. К этому моменту уже стало известно о капитуляции Риги, и перновский гарнизон, серьезно ослабевший от морового поветрия и недостатка продовольствия, не желал особо воевать. Вскоре после прибытия Боура, к нему явились два шведских офицера с просьбой отпустить находящихся в Пернове офицеров-лифляндцев по их поместьям. Русский командующий отказал, сказав, что его интересует только полная капитуляция всего гарнизона.

Swedish garrison of Riga, 10 July, 1710 (Capitulation)

Several days ago I posted a list of Riga garrison in Oct 1709 from Swedish sources (see here: http://rusmilhist.blogspot.com/2011/04/swedish-garrison-of-riga-end-of-sept.html ). It includes 12 IRs. I identified all of them except for “Ov. Dyker”. Maybe it’s Savolax (och Nyslotts) regemente? It was in the garrison of Dunamunde & capitulated several days after Riga’s fall. Hoglund mention that it was under col. J. von Cronman. No any Dyker (Duker) is mentioned as an infantry colonel at all.

Russian “Gistoria Sveyskoi voiny” (History of a war with Sweden) written by Peter the Great’s secretary Makarov has a list of Swedish garrison of Riga on July 10^th, 1710 (date of capitulation). It includes data by regiments. There 11 IRs in it. Finish indelta are named after provinces, all other – after commanders. I identified all of them except

-        Ov.-lieut. Bekker regiment (25 officers & 358 other ranks by July 10,1710)

-        Ov. Wilhelm Bekker (25 officers & 314 other ranks)

I will be pleased if someone could check these names (Dyker/Duker & both Bekker/Becker) in Lewenhaut’s Karl XII:s officerare.

               On July 10, 1710 Swedish garrison numbered 5 132 men, incl. 2 905 sick & ill. Swedish GM Clodt told Russians that epidemic of plague started when “a dog with 2 heads swam across Duna river from Kurland”.
