JR7 during the trench war period

Col. Lt. Adolf Ehrnrooth was posted as the JR7 CO on the 28th January 1943. By that time he had been badly wounded on 1.7.1941 and was still suffering from the consequences. Ehrnrooth looked like the opposite of Col. Kemppi: a nobleman, young, ethnic Swede which reflected on his pronunciation of Finnish, meticulously dressed, cavalry background.

JR7, holding the about 7 km wide Ohta sector on the Carelian Isthmus with some 3600 men, that the new CO had “inherited”from his predecessor was in a good shape, and Ehrnrooth wanted to maintain the situation. He also admitted that the trench war would not go on indefinitely, and he wanted his outfit to be prepared in the best possible manner.

First he saw to it that the field fortifications on his sector were updated: trenches, weapons nests ad dugouts were improved or new ones dug. Most casualties were seen to be due to bad positions and lack of communications trenches. Men preferred to avoid water flowing trenches and walking on the trench banks exposed themselves to enemy snipers. By late 1943 the Regiment's trench system was in exemplary order.

An interview by then Gen. Ehrnrooth around 1980:

“-I kept telling my subordinates that we must see to it that the Regiment does not get tired in this trench war phase. A healthy contact with fighting must be maintained. The first line, our wire, cannot allowed to be a terrifying final line facing no-man's-land followed by enemy positions. Our troops had to learn to operate in front of our own positions, set up ambushes and even attack enemy defensive positions either supported by fire or by surprise.

“- I know that some have said this kind of strategy caused unnecessary losses. However, I disagree. The men in the front line are not guilty of the war, but since the nation has decided to fight a war, it must be done in earnest. No half measures will do. In a defensive war no major Verdun style battles are not necessary all the time, but it must not be allowed to shrink into a “Sitting war” (German: Sitzkrieg). Every commander, including future ones, should understand this. A practical touch with fighting must be upheld constantly, bearing in mind that the casualties should be minimized. If no touch is upheld it will avenge itself in case the enemy launches a major offensive. In that case our casualties would be the double and most significant, the defence would be broken far sooner.

“- However, these fights must not be fought by volunteers. Then the Regiment would loose the elite of their men in reconnoitring attacks. If such an action is deemed necessary, it must be fought by any Company, any Platoon, any Squad, any man. On our three sub-sectors there always was one Company in reserve to be employed for such reconnoitring attacks. If there was a specific target , training in our rear was provided for the action. The missions were taken in alternate order; no volunteers were accepted. The troops actually did not like training. They were experienced in attacking, enough so to think: “ We already know what is to be done”. But actually it is just training that cuts the casualty figure.”

The outfit advanced to the jump-off positions to the S tip of Inkiläinen forest in a file, at the SW corner the order was: Platoons I, II, III, Sapper squad, Runners with I Platoon. Command Squad and Arty F.O.O. Followed I platoon. Mortar F.O.O. Followed II Platoon. Paramedics followed III Platoon. The outfit was ready in open double file at 07.45hrs

The Outfit started advancing in open double file to the breakthrough point. A gap in the two row pipe mine field in front of the wire was opened by the Sapper squad advancing with the spearhead.
The enemy opened up MG fire from the flanks whereby Cpl. Jukka was KIA. I Platoon broke through the enemy wire in the enemy positions where the bunkers on the right were firing.
I Platoon started rolling up the trench to North, destroying the dugouts at it.
II Platoon that arrived at the breakthrough point immediately after the I P started rolling up the trench to South, destroying the dugouts and weapons nests. The leading Squad of the Platoon advanced some 250m where they destroyed an enemy accommodation dugout.
III Platoon, having followed the II P through the breakthrough point, advanced past the right side of the I P in front of them, staying to secure the I P to North and East.
The strong-point had been destroyed and 2 POW taken.
The outfit disengaged like this:
I Platoon withdrew via the breakthrough point to tkk.11
III Platoon, having requested a barrage in front of them, pulled back after I P.
II Platoon requested a barrage in front of them and pulled back in two stages via the breakthrough point to tkk.11
The rear parts of the outfit found themselves on the open bog as the smokescreen over the enemy positions was temporarily lifted, the enemy fired with mortars and direct fire guns at the withdrawing outfit. In the enemy fire 3 men were KIA and 16 WIA.
The outfit had withdrawn to tkk.11.

The outfit was served in the canteen surrogate coffee and sweet buns. Rgt CO and Btn CO thanked for the accomplished mission.

The day was used to check and count the weapons and ammunition.
(End of quote)

[II Platoon did not follow orders concerning the retreating route, instead they returned along the attack route, which resulted in casualties.]

To oversee the maintenance of the fighting capability of his Regiment, Col. Lt. Ehrnrooth carried out daily inspections. Every morning he visited the front line trench, systematically from the left to the right and then vice versa. For lunch he returned to his HQ in Termola, and in the afternoon he checked rear echelons.

A by-product of his inspections was that he learned to know his men personally, Mr. Sinerma even claims that “in practice” Col. Lt. Ehrnrooth remembered the name of each of his men. When talking with their CO on personal issues the men learned to know their CO and to trust him. The men had nicknamed Ehrnrooth “Aatu”. Yet he maintained a strong discipline: he insisted on saluting, military bearing and when inspecting, the sentries had to formally report.
