The War at Sea

Blockade

When the war began, the French government ordered a blockade of the North German coasts, which the small North German navy (Norddeutsche Bundesmarine) with only five ironclads and various minor vessels could do little to oppose. For most of the war, the three largest German ironclads were out of service with engine troubles; only the turret ship SMS Arminius was available to conduct operations. By the time engine repairs had been completed, the French fleet had already departed. The blockade proved only partially successful due to crucial oversights by the planners in Paris. Reservists that were supposed to be at the ready in case of war, were working in the Newfoundland fisheries or in Scotland. Only part of the 470-ship French Navy put to sea on 24 July. Before long, the French navy ran short of coal, needing 200 short tons (180 t) per day and having a bunker capacity in the fleet of only 250 short tons (230 t). A blockade of Wilhelmshaven failed and conflicting orders about operations in the Baltic Sea or a return to FranceSecond French Empire was the 18-year Imperial Bonapartist regime of Napoleon III from 14 January 1852 to 27 October 1870. The Second Empire is given high credit for the rebuilding of Paris with broad boulevards, striking public buildings, and elegant residential districts for upscale Parisians. In international policy, Napoleon III tried to emulate his uncle Napoleon I, engaging in numerous imperial ventures around the world as well as several wars in Europe.France, made the French naval efforts futile. Spotting a blockade-runner became unwelcome because of the question du charbon; pursuit of Prussian ships quickly depleted the coal reserves of the French ships.

French warships at sea in 1870

To relieve pressure from the expected German attack into Alsace-Lorraine, Napoleon III and the French high command planned a seaborne invasion of northern Germany as soon as war began. The French expected the invasion to divert German troops and to encourage Denmark to join in the war, with its 50,000-strong army and the Royal Danish Navy. It was discovered that PrussiaThe Kingdom of Prussia was a German kingdom that constituted the state of Prussia between 1701 and 1918. It was the driving force behind the unification of Germany in 1871 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin.Prussia had recently built defences around the big North German ports, including coastal artillery batteries with Krupp heavy artillery, which with a range of 4,000 yards (3,700 m), had double the range of French naval guns. The French Navy lacked the heavy guns to engage the coastal defences and the topography of the Prussian coast made a seaborne invasion of northern Germany impossible.

The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Châlons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war.

  HISTORIC BATTLES

  Franco-Prussian War (1870 to 1871)

  Often referred to in France as the War of 1870 (19 July 1870 – 10 May 1871), was a conflict between the Second French Empire of Napoleon III and the German states of the North German Confederation led by the Kingdom of Prussia. View Historic Battle »

  Causes: In the aftermath of the Austro-Prussian War of 1866, Prussia had annexed numerous territories and formed the North German Confederation.

  Opposing forces: The French Army consisted in peacetime of approximately 400,000 soldiers, some of them regulars, others conscripts who until 1869 served the comparatively long period of seven years with the colours.

  French Army incursion: Napoleon III was under immense domestic pressure to launch an offensive before the full might of Moltke's forces was mobilized and deployed.

  Battle of Wissembourg: Upon learning from captured Prussian soldiers and a local area police chief, that the Prussian Crown Prince's Third Army was just 30 miles (48 km) from Saarbrücken near the town of Wissembourg, General Le Bœuf and Napoleon III decided to retreat to defensive positions.

  Battle of Spicheren: Moltke had originally planned to keep Bazaine's army on the Saar River until he could attack it with the 2nd Army in front and the 1st Army on its left flank, while the 3rd Army closed towards the rear.

  Battle of Wörth: The Crown Prince of Prussia's 3rd army had, on the quick reaction of his Chief of Staff General von Blumenthal, drawn reinforcements which brought its strength up to 140,000 troops.

  Battle of Mars-La-Tour: About 160,000 French soldiers were besieged in the fortress of Metz following the defeats on the frontier.

  Battle of Gravelotte: The Battle of Gravelotte, or Gravelotte–St. Privat (18 August), was the largest battle during the Franco-Prussian War.

  Siege of Metz: With the defeat of Marshal Bazaine's Army of the Rhine at Gravelotte, the French were forced to retire to Metz, where they were besieged by over 150,000 Prussian troops of the First and Second Armies.

  Battle of Sedan: The battle opened with the Army of Châlons, with 202 infantry battalions, 80 cavalry squadrons and 564 guns, attacking the surrounding Prussian Third and Meuse Armies totaling 222 infantry battalions, 186 cavalry squadrons and 774 guns.

  War of the Government of National Defence: When the news arrived at Paris of the surrender at Sedan of Napoleon III and 80,000 men, the Second Empire was overthrown by a popular uprising in Paris.

  The war at sea: When the war began, the French government ordered a blockade of the North German coasts, which the small North German navy with only five ironclads and various minor vessels could do little to oppose.

  Aftermath: The quick German victory over the French stunned neutral observers, many of whom had expected a French victory and most of whom had expected a long war.
