The "Helska", "Cyplowa" battery was formed on the basis of the order of the Chief of the General Staff of the Polish Army No.

Direct supervision of the range tests in Sweden and the subsequent assembly of the guns in Hel was exercised on behalf of the Navy by Warrant Officer Jan Lichy.

By order of the Minister of Military Affairs on June 26, 1935, it was given the name "1st Coastal Artillery Squadron Battery".

There were plans to build a second such battery (4 152.4 mm Bofors guns) on the Hel Peninsula, but the project was not implemented until the outbreak of the war.

Additionally, after 3 September, the anti-aircraft defence battery from the sunken ORP "Gryf" was included in the following: 1 wz.

On September 2 at 18:15 the battery area was bombed by 6 planes, from 18:00 At 20:00 and throughout the night of 2/3 September the battery area was bombarded by harassing raids by German seaplanes every 15–20 minutes, as a result of which the rangefinder altimeter was damaged, power cables were severed and the foundations of gun no.

Between 4 and 10 September the battery area was the object of several raids by German aircraft, according to Polish sources the crew of gun no.

17:00, the battleship "Schleswig-Holstein" was supposed to shell the battery area, damaging the power cable, shrapnel penetrated the walls of the artillery headquarters.

On September 23, at about 10:00, the battleships "Schleswig-Holstein" and "Schlesien" shelled the entire peninsula, including the area of battery XXXI, and damaged the narrow-gauge railway tracks, the road and the spare rangefinder.

The battery fought a double artillery duel with the German training battleships "Schleswig-Holstein" and "Schlesien".

The first took place on September 25, the battery's salvos gained coverage and forced the battleships to retreat under the cover of a smoke screen.

The second duel took place on September 27, ending with one hit on the casemate armor of the starboard 150 mm gun and wounding 7 crew members.

Thanks to good camouflage, the battery did not suffer any major damage during the campaign, despite air raids and battleship fire.

On 1 October, the decision was made to capitulate and after the ceasefire, partial destruction of the rangefinders and transmitters was undertaken.

In the period 1948–1949, an additional firing position was built, and the 152 mm Bofors guns were replaced with Soviet B-13 guns of caliber 130 mm (which required the reconstruction of the positions, including raising the floor by laying a 40 cm layer of concrete mix).

[5] The rebuilt battery positions, located in the military area in Hel, as well as two original 152 mm guns, have survived.

4 of the Laskowski Battalion was restored and opened to the public, along with the post-war B-13 gun preserved there and a gallery located in the basement of the position.

Since 2014, historical reenactments have been held annually on the anniversary of the capitulation of the Hel garrison in 1939 at the Heliodor Laskowski's battery.

A group of local reenactors in the uniforms of the pre-war Polish Navy reenact a fire duel with German ships and the history of the 1939 war campaign.
