Jukkola battery

[Eugenius]

Terve guys! Hope you stay healthy and already got vaccinated.))) Jukkola battery was mentioned here several times, but without details. Here is what had been found on terrain so far:

Quite heavily damaged earthen gunpit at 60.17035, 29.13944:

There are even no bolts found used for mounting the gun.

Another earthen gunpit at 60.16783, 29.15559, but now with bolts:

[Eugenius]

Unknown concrete basement close to the second gun put, right on the edge of precipice at 60.16823, 29.15629:

No idea what was that, and was it related to the battery or not.

Range-finder casemate at 60.16745, 29.15064:

[Eugenius]

Unfortunately, it is turned into dump like many others similar objects.

Command bunker nearby at 60.16767, 29.1496:

[Eugenius]

It was used by Soviet Navy after the war for not quite clear purposes, so another entrance was cut through near the initial one.

[Eugenius]

As far as I know, this position was held by 29. Rask. Ptri and it consisted of 3 guns. However, the third position was not found so far to be in a row with 2 others. Thee is a cottage settlement right in between 2 earthen positions, so the third position might be completely destroyed.

However, there is another position in that area, but made with concrete and located much closer to the shore at 60.16518, 29.15316:

No idea what kind of gun and when was installed there, and whether it had any relation to Jukkola battery.

I would be pleased to hear your comments.

Thanks for the interesting photos.

Scheme of 29.Rask.Ptri positions can be found here: http://digi.narc.fi/digi/view.ka?kuid=3193171
Edit: According to the war diary these were planned positions. Was the battery actually built as planned is unknown to me.

The drawing is an overlay to Finnish 1:20 000 topographic map sheet (see Karjalankartat.fi). As you have already found most of the positions, you can probably align drawing coordinates N6673 E452 to map grid.

Translations / map legend:
- 150 c/m(?) vh = searchlight, diameter 150 cm
- 152/45C = 6" Canet gun position
- mittaus- ja tj.paikka = rangefinder and fire control position
- keskiö = position where gun laying data was calculated

Some dates related to 29.Rask.Ptri:
- 24.7.1942 position reconnaissance for a heavy battery at Laivastoniemi. North side of road was found suitable.
- 29.7.1942 a battery with 3/152C was suggested. One gun would be transferred from Tuppura (Bay of Vyborg) and two guns from Lehtinen (Ruotsinpyhtää, Gulf of Finland), gun crews from Seivästö. [This was the plan, but reality may be different.]
- 26.8.1942 battery was ready for action.
- Winter 1944 the battery was moved inland to Jäppilä. Transfer was ready in the beginning of March 1944.
- Battery was moved back to Jukkola 4.5.1944 and destroyed by Finns in June 1944.

Gentlemen, many thanks for your interesting inputs, especially for links to archived documents. I would say that map at http://digi.narc.fi/digi/view.ka?kuid=3193171 looks to better reflect what remained and was found on terrain, even the map shown just plan of battery deployment.

I have no tools for map overlay, so I created a Google map instead: https://www.google.com/maps/d/edit?mid= ... sp=sharing Here is a picture:

If I placed co-ordination mark correctly from Karjalan kartat, all 3 gun positions more less match the map. If someone could make an overlay of these 2 maps, that would be even more visible. It would be interesting to check whether anything remained of searchlight positions - another "to do" when snow melts down completely. A big question is why only one gun emplacement was made with concrete. However, it may be considered as a fact that 3 guns were located a kind of strange way, as a "stretched triangle".

As about "actual" map... Well, I may say that only fire control and range-finding positions (I guess those are marked with 2 "stars") more or less match its actual location, but no more than that. All guns are located at absolutely different places, and the number of guns is obviously more than 3. This looks really strange.

The map shows only command post of 29.Rask.Ptri, no guns are shown. Southeast of command post seem to be 2 mortar positions?

Guns at Laivastoniemi are 4 light guns of 210.Kev.Ptri and some small direct fire guns for shore defence along the coast.

Those four guns along the coast may also have been machine guns, since line with dots on either side was the standard map symbol for them.

[Eugenius]

no guns are shown.

- well, but what those signs mean then?

Southeast of command post seem to be 2 mortar positions?

- I thought those were command post and range-finder.

Those four guns along the coast may also have been machine guns

- probably, but the signs are different - some with "dots" on the sides, some others with "strokes"

- well, but what those signs mean then?

AFAIK these are four light cannons and three machine guns.

If I placed co-ordination mark correctly from Karjalan kartat, all 3 gun positions more less match the map. If someone could make an overlay of these 2 maps, that would be even more visible.

Here's the overlay from SPK 22123 on top of 1930 Maanmittaushallitus 4012 12 MESTERJÄRVI map. The approximate WGS84 coordinates for various positions, based on karjalankartat.fi, are as follows:

Jeremianmäki 150 cm searchlight: N 60.17275, E 29.11213
Hännilä 150 cm searchlight: N 60.16697, E 29.21983
First 152/45/C: N 60.17203, E 29.14148
Second 152/45/C: N 60.16828, E 29.16432
Third 152/45/C: N 60.16536, E 29.15947
Rangefinder: N 60.16795, E. 29.15701

Thanks. It is difficult to scale and place the overlay exactly, as there is only one fixed grid reference. I would say the overlay drawing is now in a bit larger scale than topographic map. Eastern gun positions and rangefinder should be more to the west as in Google map by Eugenius.

Mangrove, many thanks for the map you created. I marked the points, which co-ordinated you defined, to my Google map: https://www.google.com/maps/d/u/0/edit? ... 70013&z=14 Here is the picture:

I would say that actual location of the known objects is a kind of to be moved south- and westwards compared to the map. The easiest explanation is that Finnish soldiers had no GPS positioning devices to define actual co-ordinates of the objects. More realistic would be to understand that the maps and positioning capabilities of those times were far less accurate than those we have now. It could be also possible that actual location of objects was changed compared to the initial plan.

As about added objects, I may comment as follows:

Jeremianmäki 150 cm searchlight - it was probably located right in the middle of the area now being used for building a cottage settlement. Satellite pictures show levelled plots of land prepared for house building. I do not think anything could remain of the searchlight basement.

Hännilä 150 cm searchlight - it is located now in between of roads in another cottage settlement; something could remain.

Another issue is the obvious difference between how the objects were mapped and how they are actually located, so trying to find searchlight basements, a certain amendment should be taken into consideration, but such an amendment looks to be different for every object.
