What use were cavalry in WW1? Now I know that they transported things and other stuff, but what use were cavalry regiments that fought? They would get obliterated in the trenches.
EDIT: Sorry for double post.
With cavalry they were trained in more of a dragoon role at the beginning of the war, although this did vary from army to army. The British Army had had to fight the Boer Commandos so had learned a little from that. Whilst there were plenty of officers who thought that a traditional cavalry charge would win the war in a day it was clear that was not going to happen. Contrary to films, we never did launch many charges and the few times we did we did not even get close to the enemy lines (we got held up by barbed wire that the Belgian farmers had put there before the war). Funnily enough in 1918, when the fighting moved out of the trenches, they had a use again (mainly reconnaissance) but also supporting the armour and infantry. During the Germans first Spring offensive a Canadian Cavalry regiment charged the Germans and helped slow up the advance although they suffered very heavy casualties. I think the Belgians launched the last cavalry charge of the Great War in October of 1918. For most of late 1914 to early 1918 though the cavalry was either dismounted and sent to the trenches or remained in reserve for the breakthrough that never came.
As others have said, on the Eastern Front cavalry was used extensively. The Eastern Front was much longer than the Western Front so it was impractical to build a continuous line of trenches like in the west. Probably the most famous Cavalry Charge of the war was at Beersheba in late 1917 where the ANZAC Cavalry charged the Turks. If my memory serves me right the Turks forgot to adjust their sights so their shots largely missed the oncoming cavalry.
Here are some articles for more information on the cavalry that fought on the Western Front:

Did Finland have any value or was it just a piece of land during the 18th century?
I am not an expert on the Great Northern War, nor the Russo-Swedish conflicts over Finland which continued on and off till the Napoleonic Wars, but I would imagine that it would have been vital in controlling the Baltic, not to mention the lumber that could be used. I am not sure if Finland possessed any other resources that would have been useful.
