What is the easiest way to find these, as they say in Finnish "from the national school base"...

Here are complete set of 1:20 000 topographic maps made in 1943 and 1944 by Topografipataljoona. Apparently the scans are made from originals at the National Archives of Finland and/or National Defence University library.

Hi, thank you very much.
I actually knew this link but couldn't remember. Now it's stored, not just in memory.
best regards Jukka
btw there`s much more, Rukajärvi etc.

Hi

Could somebody help with H -squares used to report position during the continuation war.
At present I am writing about the war on the Hanko isthmus june-december 1941. Observation (target) position was referred with the letter H and a 5-digit number. I have a few references, but not enough to solve how the code was built. It also seems that it is not linear. Squares on consecutive rows do not end in the same digits. These H-squares were mostly used at sea, in in my case the water between Hanko and Hitis,

Some examples:
H 49459 Maltskär
H 49474 Ljusskär
H 49492 Tulludden, Hangö
H 49496 Rödskär

It would be great if somebody could advise on the algorithm, or provide a link to a map with the system. My guess is that I do not need a map of the Hanko area, any identifiable area with sufficient info to expand the square pattern will do.

Thanks

And btw, thanks for the info abouve on the maps, will be needed for the next project,JR24, where my granddad served from 1941.

Hello out there.

I did manage to resolve the issue from a lot of separate reports.

It just took some three years.

Here are my results. Attached as a map.

It seems tar he system was abandoned after Russians left the Hanko area in early December 1941.

For further investigation the mentioned coordinate system seems to have been abandoned from beginning of 1942.

I am unable to upload the result because the file i too large (sic). Anybody interested can request it from me though.

You can find some information on the Finnish reporting map systems from these links.

Hi,

Thanks for your kind information.

As mentioned, I write about the events on the Hanko peninsula in 1941. For long I was unable to solve the H squares used mainly in the Hilo (Hitis) area. The puzzle started to solve when processing the LLv 6 (Lentolaivue 6) diaries. There was references to H squares and island names, etc mainly in the gulf of Finland and on the Estonian coast. Plotting these on a map (Suomenlahden Ilmoituskartta ) solved the system. The square numbering is not linear.
There was not enough info on squares close to St Peterburg (Leningrad at the time) to solve those squares and squares w of Hitis had also too little info in LLv 6 diaries. Note anyhow that a new number series appear in the lower left.

In the LLv 6 diaries were also some interesting info on how the Germans proceeded in Estonia. As i could not find a suitable background map in the public domain, I made one. Below is a situation map for 24.8.1941.
