Battle of Westerplatte


The Battle of Westerplatte was one of the first battles in Germany's invasion of Poland, marking the start of World War II in Europe. Beginning on 1 September 1939, German army, naval and air forces and Danzig police assaulted Poland's Military Transit Depot on the Westerplatte peninsula in the harbor of the Free City of Danzig. The Poles held out for seven days and repelled 13 assaults that included dive-bomber attacks and naval shelling.
Westerplatte's defense served as an inspiration for the Polish Army and people in the face of German advances elsewhere, and is still regarded as a symbol of resistance in modern Poland.

Background

Westerplatte is a peninsula in the Bay of Gdańsk. Following the reestablishment of Polish independence after World War I, much of the surrounding region became part of Poland. However, the city of Danzig, historically an important port city, became an independent city-state, the Free City of Danzig. The Free City was nominally supervised by the League of Nations but, over time, Danzig became increasingly allied with Germany, reflecting its predominantly ethnic German population.
In 1921, in the wake of the Polish-Soviet War, the League of Nations granted Poland the right to install a garrisoned ammunition depot near Gdańsk. Despite objections from the Free City, this right was confirmed in 1925, and an area of was selected on the Westerplatte peninsula. Westerplatte was separated from the New Port of the Free City of Danzig mainly by the harbor channel; on land, the Polish-held part of Westerplatte was separated from Danzig's territory by a brick wall topped with barbed wire. A dedicated rail line, passing through the Free City, connected the depot with nearby Polish territory. The depot, referred to in League documents as the , was completed in November 1925, officially transferred to Poland on the last day of that year, and became operational shortly after in January 1926, with 22 active storage warehouses. The Polish garrison's complement was set at 88 soldiers, and Poland was prohibited construction of further military installations or fortifications on the site.
By early 1933, German politicians and media figures complained about the need for border adjustments. In addition, Polish and French discussed the need for a preventive war against Germany. On 6 March 1933, in what became known as the "Westerplatte incident" or "crisis", the Polish government landed a marine battalion on Westerplatte, briefly reinforcing the outpost to about 200 men, demonstrating Polish resolve to defend the outpost; more locally, the Polish maneuver was also intended to put pressure on the Danzig government, which was trying to renounce a prior agreement on shared Danzig-Polish control over the harbor police and to acquire full control of the police and the harbor. The additional Polish troops were withdrawn on 16 March 1933, following protests from the League, Danzig, and Germany, but only in exchange for Danzig's withdrawal of its objections to the harbor-police agreement. According to another source, on 14 March 1933 the League had authorized Poland to reinforce its garrison.
Over subsequent years, the Poles constructed clandestine fortifications on Westerplatte. These were not impressive: there were no bunkers or tunnels, only several small outposts, partially hidden in the peninsula's forest, and several more buildings in the peninsula's center, including barracks. Most buildings were constructed with reinforced concrete, and were supported by a network of field fortifications.

Prelude

In March 1939, a German ultimatum to Lithuania led to Germany's annexation of the nearby Lithuanian coastal Klaipėda region; subsequently, the Westerplatte garrison was placed on alert. Fearing a possible Nazi coup d'etat in Danzig, the Poles decided to secretly reinforce their garrison and, for that purpose, resorted to a subterfuge: civilians in Polish Army uniform would leave the base, and new Polish soldiers would enter it.
By late August 1939, the Poles had reinforced their 88-man garrison, though its strength is still debated; older sources speak of 182 men, but more recent research suggests something in the range of 210 to 240, including six officers: Major Henryk Sucharski, Captain Franciszek Dąbrowski, Captain Lieutenant, Lieutenant, and Second Lieutenant. Estimates include some 20 mobilized civilians and about 10 regular troops who happened to be on site when fighting began. In addition to light arms, weaponry included a, two antitank Bofors 37 mm guns, four, and about 40 machine guns, including 18 heavy ones. Field fortifications were extended: more trenches were dug, wooden barricades were built, barbed wire was strung into wire obstacles, and reinforced concrete shelters were built into the basements of the barracks. Foliage was thinned to reduce cover from expected avenues of attack.
The Polish defense, which anticipated principally a German land-based assault, rested on three lines of defense. The outer line included entrenchments which were to hold long enough for the garrison to mobilize. The second line of defense centered on the six outposts. The final defense comprised the headquarters and barracks at the depot's center. The plan called for Westerplatte to hold out for 12 hours, after which the siege was expected to be lifted by Polish reinforcements arriving from the mainland.
On 25 August 1939 the German pre-dreadnought battleship, under the pretext of making a courtesy call, sailed into Danzig harbor, anchoring from Westerplatte. On board was a Marinestosstruppkompanie with orders to launch an attack on Westerplatte on the morning of 26 August 1939. For their planned attack on Westerplatte, the Germans had an SS Heimwehr Danzig force of 1,500 men under Police General Friedrich-Georg Eberhardt, and the 225 marines under Lieutenant Wilhelm Henningsen. In overall command was Captain Gustav Kleikamp, aboard the Schleswig-Holstein. On 26 August he moved the battleship farther upstream. Major Sucharski, commanding Westerplatte, put his garrison on heightened alert. Shortly before the German disembarkation, the orders were rescinded. Hitler had postponed hostilities on learning of the Polish-British Common Defence Pact, signed the day before, on 25 August 1939, and that Italy was hesitant about its obligations under the Pact of Steel.
Neither General Eberhardt nor Captain Kleikamp had specific information on the Polish defenses. The Germans assumed that preliminary bombardment would soften up the fortifications enough for the marines to capture Westerplatte. Reportedly Captain Kleikamp had been assured by the Danzig police that "Westerplatte would be taken in 10 minutes." General Eberhardt himself was more cautious, estimating that "a few hours" would be needed to overcome the Polish garrison, which the Germans estimated at no more than 100 men.

Battle

On the early morning of 1 September 1939, the Schleswig-Holstein suddenly fired a broadside salvo at the Polish garrison. That salvo's time has been variously stated as 04:45, 04:47, or 04:48. Polish historian Jarosław Tuliszka explains that 04:45 was the planned time, 04:47 was the time the order was given by Kleikamp, and 04:48 was the time the guns actually fired. Shortly after, on Westerplatte, Major Sucharski radioed the nearby Polish military base on the Hel Peninsula, "SOS: I'm under fire."
Eight minutes later Lieutenant Wilhelm Henningsen's marines from the Schleswig-Holstein advanced, expecting an easy victory over the Poles. A Polish soldier, Staff Sergeant Wojciech Najsarek, was killed by machine-gun fire, the first combat casualty of the battle and perhaps of the war. However, soon after crossing the artillery-breached brick wall, the Germans stepped into an ambush. They found themselves in a kill zone of Polish crossfire from concealed firing positions, while barbed-wire entanglements impeded their movements. The Poles knocked out a German Schutzpolizei machine-gun nest, and Lt. Leon Pająk opened intense howitzer fire on the advancing Germans, who faltered and broke off their attack. The single 75 mm field gun fired 28 shots, knocking out several machine-gun nests atop warehouses across the harbor canal, before it was destroyed by the battleship's guns.
At 06:22 the German marines frantically radioed the battleship that they had sustained heavy losses and were withdrawing. The Danzig police had tried to seize control of the harbor on the other side of Westerplatte, but had been defeated. Casualties were approximately 50 Germans and eight Poles, mostly wounded. A longer bombardment from the battleship, lasting from 07:40 to 08:55, preceded a second attack. The Germans tried again from 08:35 to 12:30 but encountered mines, felled trees, barbed wire, and intense fire. By noon the Germans retreated, Henningsen gravely wounded.
On the first day's combat, the Polish side had sustained four killed and several wounded. The German marines had lost 16 killed and some 120 wounded.
The German commanders concluded that a ground attack was not feasible until the Polish defenses had been softened. Re-examining aerial photographs, where they had previously underestimated Polish defenses, they now overestimated them, concluding the Poles had constructed extensive underground and armored fortifications. In the following days, the Germans bombarded the Westerplatte peninsula with naval and heavy field artillery, including a 105 mm howitzer battery and 210 mm mortars. On 2 September, from 18:05 to 18:25, a two-wave air raid by 60 Junkers Ju 87 Stuka dive bombers dropped 26.5 tons of bombs, taking out the Polish mortars, destroying Outpost Five with a 500 kg bomb, and killing at least eight Polish soldiers; the air raid shrouded all of Westerplatte in clouds of smoke and destroyed the Poles' only radio and much of their food supplies. According to some German sources, after the air raid the Poles briefly displayed a white flag; but not all historians are convinced of this, and the German observers may have been mistaken.
On 4 September, a German torpedo boat, the T196, supported by an old minesweeper, the Von der Gronen, made a surprise attack from the sea side. The Poles' Wał post had been abandoned, and now only the Fort position prevented an attack from the north. Though the Poles never landed a hit on the German naval units, the T196 and the Schleswig-Holstein suffered accidents due to crew error or equipment failure, with at least several injured men and at least one fatality on the battleship.
On 5 September Major Sucharski held a conference with his officers, during which he urged surrender: the post had only been supposed to hold out for twelve hours. His deputy, Captain Franciszek Dąbrowski, opposed surrender and the group decided to hold out a while longer.
Subsequently, the Poles repelled several cautious German probing attacks by the marines, Danzig SS and police, and Wehrmacht. At 03:00 on 6 September, during one of the attacks, the Germans sent a burning train toward the land bridge, but the ploy failed when the terrified driver decoupled prematurely. The train failed to reach the oil cistern and set fire to the woods, which had provided the Poles with valuable cover. In addition, the flaming wagons created a perfect field of fire, and the Germans suffered heavy losses. A second fire-train attack, in the afternoon, likewise failed.
, 8 September, after the battle
At a second conference with his officers, on 6 September, Sucharski was again ready to surrender: the German Army was by now outside Warsaw, and Westerplatte was running critically low on supplies; moreover, many of the wounded were suffering from gangrene. At 04:30 on 7 September the Germans opened intense fire on Westerplatte which lasted till 07:00. Flamethrowers and bombardment destroyed Outpost Two and damaged Outposts One and Four. The Schleswig-Holstein took part in the bombardments.
At 09:45 on 7 September 1939 a white flag appeared. The Polish defense had so impressed the Germans that their commander, General Eberhardt, let Sucharski keep his ceremonial szabla in captivity. Contemporary English-language publications misidentified the Polish commander as a Major "Koscianski".
Sucharski surrendered the post to Captain Kleikamp, and the Germans stood at attention as the Polish garrison marched out at 11:30. Over 3,000 Germans had been tied up in the week-long operation against the small Polish garrison; about half of the Germans had taken part in direct action. German casualties totaled 50 killed and 150 wounded. The Poles had lost 15 men and had sustained at least 40 wounded.

Aftermath

On 8 September, the day after the capitulation, the Germans discovered a grave with the bodies of four unidentified Polish soldiers who had been executed by their comrades for attempted desertion. This had likely taken place following the 2 September air raids.
Five days after the capitulation, on 12 September 1939, the Polish wireless operator, sergeant Kazimierz Rasiński, was murdered by the Germans. He was shot after brutal interrogation during which he refused to hand over radio codes.
On 19 September Adolf Hitler came to visit Gdańsk. While there, on 21 September, he inspected Westerplatte.
Controversy surrounds the Polish garrison's commanding officer, Major Henryk Sucharski, and his executive officer, Captain Franciszek Dąbrowski. Early historiography considered Major Sucharski to have been in command throughout the battle, and consequently early accounts portrayed him as a heroic figure. More recent accounts from the early 1990s have presented evidence that Sucharski's officers had vowed not to disclose in their lifetimes that their commander had been shell-shocked for most of the battle and had advocated surrender as early as 2 September, and several times thereafter; and that Captain Dąbrowski had effectively taken command following Sucharski's breakdown on the second day of the siege. Sucharski's conduct is still debated by historians.

Remembrance

The Battle of Westerplatte is often described as the opening battle of World War II, but it was only one of many battles in the first phase of the German invasion of Poland known as the Battle of the Border. I. C. B. Dear described the Schleswig-Holstein's salvos as having occurred "minutes after Luftwaffe attacks on Polish airfields" and other targets. A bridge in nearby Tczew had been bombed around 04:30 hours, and the false-flag Operation Himmler had begun hours earlier.
The Polish historian writes that "Westerplatte has become one of the symbols of the Polish struggle for independence, and is inscribed in the list of the most heroic battles of modern Europe."
For both sides the battle had mostly political, rather than tactical, importance. Still, it did tie up substantial German forces for much longer than anyone had expected, notably preventing the Schleswig-Holstein from lending fire support in the nearby battles of Hel and Gdynia.
Westerplatte's defense inspired the Polish Army and people even as German advances continued elsewhere; beginning 1 September 1939, Polish Radio repeatedly broadcast the phrase that made Westerplatte an important symbol: "Westerplatte broni się jeszcze". On 16 September Konstanty Ildefons Gałczyński penned a poem, Pieśń o żołnierzach Westerplatte, voicing a subsequent myth that all of Westerplatte's defenders had died in the battle, fighting to the last man. The battle became a symbol of resistance to the invasion – a Polish Thermopylae. As early as 1943, a Polish People's Army unit was named for Westerplatte's soldiers. That same year the Polish Underground State named a street after Westerplatte; and the following year, during the 1944 Warsaw Uprising, an insurgent stronghold was named Westerplatte.
The Polish 75 mm field gun became one of Germany's first war trophies of World War II, displayed on a column at Flensburg. After the war it was moved to stand before the Naval Academy Mürwik.
Westerplatte's Outposts One, Three and Four, the power plant, and the barracks survived the war. In 1946 a Cemetery of the Defenders of Westerplatte and a Tomb of the Unknown Soldier were established on the peninsula; the cemetery was placed near the destroyed Outpost Five. During the early postwar Stalinist era, Westerplatte was presented as a symbol of Poland's prewar anticommunist government and was marginalized in official history; Dr. Mieczysław Słaby, the garrison surgeon at Westerplatte, was arrested and tortured and died in the custody of the Ministry of Public Security in 1948. After the mid-1950s liberalization, Westerplatte began to be used as a propaganda symbol; in 1956 the Polish Naval Academy was named for the "Heroes of Westerplatte", and that name began to be given to schools, streets, and other institutions. In 1962 a Christian cross at the cemetery was replaced with a Soviet T-34 tank, and the first government-organized remembrances began at Westerplatte. In 1966 a, also known as the "Historical Monument, Site of the Battle of Westerplatte", a 25-meter-tall obelisk atop a mound, was erected at Westerplatte, set within a park, with smaller installations. Westerplatte became a popular tourist attraction. Later Outpost One was relocated in order to save it from destruction in the construction of a new harbor channel. In 1971 Major Sucharski's grave was relocated to Westerplatte from his original burial in Italy. In 1974 a small museum was opened in the renovated Outpost One. Since the 1980s Westerplatte has been administered by the National Museum in Gdańsk. In 1981 the cross was restored to the cemetery. In June 1987 Westerplatte was visited by Pope John Paul II; his visit is commemorated by a plaque unveiled in 2015. A change symbolic of Poland's political transformation was the removal of the Soviet T-34 tank from the cemetery. In 2001 the Polish government recognized Westerplatte's ruins as an object of cultural heritage. On 1 September 2003 the site was designated an official Historic Monument. In the mid-2010s the Polish government decided to create a dedicated, commemorating the 1939 battle; the museum is to open in 2019.
Westerplatte is a common venue for remembrance ceremonies, usually held on 1 September, relating to World War II. They are generally attended by high-ranking Polish politicians such as Prime Minister Donald Tusk, President Bronisław Komorowski, President Andrzej Duda, and Prime Minister Beata Szydło. The commemoration of the 70th anniversary of the outbreak of World War II, in 2009, was attended by Prime Minister Tusk, former Prime Minister Tadeusz Mazowiecki, and former Presidents Lech Wałęsa and Aleksander Kwaśniewski, as well as by important figures from about 20 other countries, including German Chancellor Angela Merkel, Russian Prime Minister Vladimir Putin, Ukrainian Prime Minister Yulia Tymoshenko, and French Prime Minister François Fillon.
The Battle of Westerplatte has been the subject of two Polish films: Westerplatte, and Tajemnica Westerplatte. It has also inspired dozens of books and scores of press articles, scholarly studies, and fictional works, as well as poems, songs, paintings, and other works of art.
