Fredericia and Jutland 1849
 
  After the Danish army had moved towards  Schleswig, they won the first battle at Bov, but was shortly after faced by superior
  forces. The Danish army retreated and large parts of Jutland was occupied. The fortress at the city of Fredericia was
  considered impossible af a redoubt, since the fortress had not been maintained for 100 years and was not suitable for war.
  Soon after, a ceasefire was agreed, which  lasted until April 1849. The ceasefire, however, had been so unfavorable to
  Denmark, that the Danes almost looked forward to resuming the war.
  The war was actually resumed in 1849.
  The Danish army was now facing the Prussian general Prittwitz with a total of 61,000 men and General Bonin,  who led the
  special Schleswig-Holstein strength of 14,000 men.
  The Danish army counted only 41,000 men, and they had to retreat to the island Als and to the fortress og Fredericia.  
  Fredericia had meanwhile been combative, and parts of the Danish force went into the fortress, while other parts pulled back
  to the island Funen.
  General Rye pulled by a slow retreat the German main force further up in Jutland. General Bonin and his Schleswig- Holstein
  army was by his commanding general ordered to prevent the Danes from attacking the German forces from  the fortress of
  Fredericia. 

General Bonin

General Prittwitz

 On May 7th General Bonin arrived with the army of 14,000 men to the City of Fredericia and during the first week they built the
 first fortifications.
 From Rendsburg he had procured 14 pieces of siege artillery and already the May 16^th a bombardment of the city began.
 The bombardement  started at 3:00 in the morning.
 The four 168-pound mortars were the most effective. 49 houses were destroyed and 200 damaged. The people fled to the
 Citadel, where they felt themselves most secure. Several, however, continued to the Funen.
 The bombardment had no effect on the city's defense capability, and only a few lives were lost. The Soldiers' morale could
 not be weakened as long as the lifeline to the Funen could be maintained.
 General Bonins next move was to move the batteries nearer the harbor, and enable them shoot at piers and shipping. The
 jetty facilities at Strib were destroyed, but the Danes brought several new jetties
 farther east, outside the reach of the enemy artillery. Instead Bonin launched an artillery battle during the period june 3th to
 june 17^th, attempting to bombarde the fortress and the city.
 The combat got more and more the character of a decisive battle, and the Danish artillery did everything they could. It was
 now apparent that the fortress artillery were superior to the German , not least by much more ammunition.
 The Bonin artillery was, gun by gun, destroyed and could not be replaced. For example, half of the powerfull 168 pound
 mortars were destroyed.
 At the same time the attacker suffered from a  June, that this year was unusually cold and rainy, and the failed attacks
 seemed
 to lower the morale by the soldiers.

Belejrings-morter

Princippet i morteren

  General Bonin was at this time aware, that reinforcemants were brought from the outside to Fredericia.
  Because the Danisk navy had absolute superiority at sea, it was possible to transport soldiers and equipment from both the
  Funen in the east, the Island Helgenæs in the north and from Als and Soenderborg in the south without being disturbed.    
  He had the choice to pull back and get ready for aDanish attack from the fortress, og to or even abolish the siege and  
  withdraw even farther away.
  He chose to stay in the besieged position.
 
  The outcome of the Danish attack July 6th 1849

  General Bülow's plan was to assemble a large army in Fredericia, make a sortie and add Bonin and his Schleswig Holstein
  army a serious defeat. For this undertaking  General de Meza brought a brigade of 5 battalions, a total of 5000 soldiers from
  Als, and general Rye brought from Helgenæs 4,000 men.
  This total numbers of the Danisk army in Fredericia were now 23,000 , opposing the 14.000 from the Schleswig-Holstein rebel
  army outside. .
  On a council of war on July 4^th 1849 at Vejlby rectory, General Bülow maintained an overall attack from the fortress.  The
  situation was favorable because the enemy was divided into four independent groups. In some places, the gap between the
  groups up to 1 kilometer  wide. Because of the Danish fortress artillery  range, there was also a huge gap between the
 Schleswig-Holstein frontline and camps, where the reserves were located. General de Meza should push forward on the
 northern front between the Holstein's posts
 and separate them. General Schleppegrells brigade would follow and capture positions south of it and general  Rye had to
 walk up along the beach and attack and conquer the posts on the coast with his brigade og 5000 men  while the Moltke
 brigade would follow.
 There was hard fighting around the redoubt No. III, who managed to obtain reinforcements  from behind. Only when general
 Bonin pulled his troops away, the redoubt was conquered. The redoubt No.  V (Trelde redoubt) also made great resistance. 
  he Danish troops surrounded it and even intercepted  the reinforcement from the camp behind it.
 Molktes brigade of 1000 men succeeded to occupy the redoubt , which was defended by 200 men.
 The brigades of Schleppegrell and Moltke now surrounded the remaining enemy redoubts and captured them.

Angrebet på Trelleskanse

 Originally it was General Bülow's plan two dig in the troops on the grounds outside the Fredericia fortress, but he changed
 his decision, and at 8 pm. All the remaining soldiers were back behind the rampages and artillery in Fredericia
