The British Royal Air Force (RAF) fighters and bombers made daylight raid on Northern 
France. Thirty Luftwaffe fighters destroyed for loss of two. Bremen and Wilhelmshaven 
main targets of night raids. Others were Emden, Bremerhaven and Duesseldorf.  
 
The Russian front  Operation Barbarossa The Wehrmacht 
had amassed 3,206,000 soldiers and over 3,330 assorted panzers. Over 7,100 artillery 
pieces 600,000 motor vehicles 625,000 horses 250 assault guns, the Luftwaffe had 
amassed 2,840 aircraft.   
Northern Sector  Erich 
Hoepner, 4th Panzer group attacked from the East Prussian frontier north of 
Memel and south of Tilsit. Supported by heavy artillery fire, and air intervention, 
Georg-Hans 
Reinhardt 41st Panzer Corps and Erich 
von Manstein 56th Panzer Corps struck Sobennikov's 8th Army, taking the Soviet 
command by surprise. Forward units were easily overrun. Erich 
von Manstein 56th Panzer Corps pierced the 8th Army's left flank and advanced 
quickly through closely wooded territory, and went by Rasainiai to reach the Dubissa 
River and secure a crossing after a audacious assault upon their Airogola viaduct. 
 
 Rasainiai fell to supporting in infantry after a brief engagement Georg-Hans 
Reinhardt 41st Panzer Corps launched its assault from Tilsit, hitting a single 
rifle division in the centre of the 8th Army with two panzer, one motorised and 
one infantry divisions. The lone defending division fighting desperately at the 
frontier was unable to hold back the German attacks and collapsed opening the 
road to Taurage. Pushing deep into the frontier zone Georg-Hans 
Reinhardt 41st Panzer Corps, The advance was slower than Erich 
von Manstein 56th Panzer Corps as the Soviets hurled repeated counter-attacks. 
Fyodor Kuznetsov attempted to rally his forces throughout the day, but the Luftwaffe's 
air superiority precluded any effective countermeasures at the border. The Headquarters 
of the Baltic military district, now renamed the North West front at Subach, along 
with many Soviet command and communication facilities came under fierce attack 
by the Luftwaffe As the panzers pressed ahead, the infantry began their long march. 
 The 18th Army commanded by Georg 
von Küchler moving out of its cramped assembly areas behind Erich 
von Manstein 56th Panzer Corps fanned out into Lithuania, pressing north along 
the coast towards Libau to lever the right flank of the 8th Army away from the 
coast. Further inland, costly engagements raged along woodland tracks, a small 
detachments of Soviet troops ambushed German units delaying the advance before 
they were destroyed or pulled back into the interior.
 General Ernst 
Busch, led his infantry forward on the right wing of Heeresgruppe Nord (Army 
Group North) pushing East from the East Prussian border towards Niemen River. 
These units hit the right wing of the 8th Army and the northern wing of the 11th 
army. Seriously shaken Fyodor Kuznetsov, armies started to break up. Early on 
in the day as Erich 
von Manstein 56th Panzer Corps drove along the road to Airogola viaduct, Fyodor 
Kuznetsov ordered the 3rd and 12th Mechanised Corps to concentrate for a counter-attack 
aimed at stopping the Germans pushing towards Siauliai. Subordinating both corps 
to the 8th Army commanded by Fyodor Kuznetsov ordered an attack at midday on the 
23rd June 1941. The 12th Mechanised Corps ordered its forces to co-operate with 
the 3rd Mechanised Corps and attack the Germans at Taurage. However, due to the 
catastrophic break down of communications the battlefront commander was for the 
most part unaware of the dangerous situation evolving on the 11th army's sector. 
In essence Fyodor Kuznetsov was coping with a lesser of two evils his movements, 
only delaying Georg-Hans 
Reinhardt 41st Panzer Corps, advance momentarily, while Erich 
von Manstein 56th Panzer Corps pressed almost unhampered towards the Dvina 
River.  
Central Sector  Fedor 
von Bock Heeresgruppe Mitte (Army Group Centre) started its offensive, as 
the Luftwaffe arrived over Soviet air bases and military facilities behind the 
frontier. South West of Vilnius, Hermann 
Hoth 3rd Panzer Group ripped open the southern flank of Morozov 11th Army 
pushing the East for the Niemen River. With the 57th Panzer Corps on the left, 
39th Panzer Regiment to its right and infantry following, Hermann 
Hoth 3rd Panzer Group severed the joint of the North West and West Front. 
As a consequence, Fyodor Kuznetsov was required to detach the 12th Mechanised 
Corps and the 3rd Mechanised Corps from Sobennikov's 8th Army and bring them South 
to aid the collapsing 11th Army. Even so, the movement of the two mechanised corps 
was harassed by the Luftwaffe, and was finally be halted by Georg-Hans 
Reinhardt 41st Panzer Corps in the first major tank battle of the campaign. 
 As the advance of the panzers got underway General Adolf 
Strauß 9th Army hit forward elements of Fyodor Kuznetsov 3rd Army. The 
surprised Soviet forces already out of touch with their Headquarters and hard 
pressed by German ground and air attacks endured awful casualties. Provisions 
ran low towards the end of the day due to relentless Luftwaffe attacks on forward 
supply dumps. The cohesion of the hard-pressed battlefront formations began to 
collapse after just the first few hours of armed combat. 
 Close to Grodno 
German infantry were involved in a ferocious struggle with the Soviets Fyodor 
Kuznetsov vainly tried to bring his armour into the battle. But despite that fact 
the 11th Mechanised Corps was deployed close to Grodno, it could not deploy being 
hampered in its movements by Albert 
Kesselring 2nd Air Fleet. Soviet armoured losses on the approach roads were 
crippling.
 In the centre of the Heeresgruppe. Heinz 
Guderian 2nd Panzer Group launched a ferocious assault upon the garrison of 
Brest-Litovsk. Despite repeated attacks, they were not able to capture the city, 
the NKVD (The People's Commissariat for Internal Affairs) border guards, put up 
fierce resistance. After confused fighting in the outskirts the Soviets pulled 
back into the citadel and prepared to resist a sustained German siege. North and 
South of the city, the rest of Heinz 
Guderian 2nd Panzer Group started their offensive. 
 Joachim 
Lemelsen 47th Panzer Corps moved across the river Bug north of the town and 
pushed towards Pruzhany, where it met resistance from elements of the 14th Mechanised 
Corps. Leo 
Geyr von Schweppenburg 24th Panzer Corps, succeeded in crossing the River 
Bug south of Brest. As armour penetrated the Soviet defences The marching infantry 
of Günther 
von Kluge 4th Army got to grips with the Soviets left behind. As with the 
Hermann Hoth 
3rd Panzer Group, infantry came after each armoured corps of Heinz 
Guderian 2nd Panzer Group. 
 As in the North in the centre the Germans 
had taken the Soviets completely by surprise. The 3rd, 4th and the 10th Armies, 
together with battlefront commander Dmitry Pavlov, having been caught completely 
unawares. Many Soviet units were under continuous ground and air attack and broke 
up in the first few hours of fighting. Nevertheless isolated detachments fought 
back ferociously inflicting heavy casualties upon the attacking German divisions. 
 The Luftwaffe was extremely active throughout the day, bombing Soviet concentrations 
at Bialystok, Grodno, Lida, Volkovsky, Brest-Litovsk and Kobrin the latter Headquarters 
of Andreevich Korobkov 4th Army communications throughout the now redesignated 
West Front collapsed leaving Dmitry Pavlov, unaware of the disasters that were 
unfolding around him. In only two hours constant Luftwaffe attacks managed to 
shatter the command structure of the 4th Army. Fuel and ammunition dumps, came 
under particularly fierce attack, while numerous airfields were disabled. K.D. 
Golubev 10th Army, deep inside the Bialystok salient also came in for a considerable 
beating many of its supply facilities being lost. 
 Across the Central 
sector, the Soviet defences continue to remain wide open. K.D. Golubev 10th Army, 
in spite of fierce fighting were already losing their battle against Adolf 
Strauß 9th Army and Günther 
von Kluge 4th Army. With much of his rear services destroyed. It was only 
a matter of time before the army bled to death. K.D. Golubev reported to Dmitry 
Pavlov, that is 6th Cavalry Corps had been all but decimated and the remnants 
of his frontier rifle divisions were falling back. In an effort to restore the 
situation, Dmitry Pavlov, ordered the 14th Mechanised Corps to move from Pruzhany 
and launch an immediate counter-attack to throw the Germans back to the border. 
Despite severe difficulties in deploying the 14th Mechanised Corps managed to 
engage the 18th Panzer Division (Joachim 
Lemelsen 47th Panzer Corps) and embroiled it in a drawn-out armoured dual 
for most of the day. 
 By dusk, the Germans had committed elements of the 
28th Rifle Corps (Günther 
von Kluge 4th Army) in Brest-Litovsk and determined to capture the city as 
quickly as possible. At the same time K.D. Golubev decided to begin the withdrawal 
of his 10th Army behind the Narew River to prevent its encirclement the collapse 
of his northern and southern flanks having jeopardised the whole army. The 6th 
Mechanised Corps was ordered to move up to the Narew River to protect the rear 
of the retiring rifle divisions. In an effort to ascertain what was happening 
at the K.D. Golubev 10th Army, Dmitry Pavlov sent his deputy General Boldin, to 
K.D. Golubev unit. Late in the evening General Boldin managed to locate K.D. Golubev, 
whose Headquarters had been moved to some woods South West of Bialystok. Here 
General Boldin was informed that the 10th Army had suffered extremely severe casualties, 
and the 6th Mechanised Corp's was badly short of tanks, but was moving to the 
east bank of Narew River to cover the withdrawal of the frontier units. Reporting 
these developments to Dmitry Pavlov, General Boldin was ordered to put a shock 
group together to stop any potential German incursion towards Volkovysk. During 
the night of the 22nd to 23rd June 1941 General Boldin trying to put together 
his small force. He planned to attack towards Grodno from the Northeast of Bialystok, 
where he assumed the 11th Mechanised Corp was already in action.  
Southern 
Sector  Field Marshal Rudolf 
von Rundstedt Heeresgruppe Süd launched the first phase of its offensive 
against Soviet forces in the north west Ukraine. Once again the Luftwaffe was 
very active, attacking Soviet defences and airfields across the entire combat 
sector. Within hours the Luftwaffe had destroyed nearly 300 Soviet aircraft. While 
the Luftwaffe pounded Soviet ground and air forces, German panzers and infantry 
crossed the frontier. Paul 
von Kleist 1st Panzer Group with Walter 
von Reichenau 6th Army in close support, crossed the border between Rava-Russki 
and Strumilov to maintain pressure upon the joint of the Soviet 4th, 5th and 6th 
Armies. In the Rava-Russki region the 6th Rifle Corps was heavily engaged and 
despite bitter fighting, failed to prevent German forces crossing the River Bug. 
Assault troops successfully overwhelmed the NKVD (The People's Commissariat for 
Internal Affairs) guards on the bridges over the River Bug, opening the road to 
the interior. 
 The 3rd Panzer Corps, 14th and the 48th Panzer Corps of 
Paul 
von Kleist 1st Panzer Group were able to begin their advance towards Kiev, 
with only minor losses. Carl-Heinrich 
von Stülpnagel 17th Army also attacked, aiming to crush the Soviet 6th 
and 26th Armies deployed around Lvov. Fierce battles raged between Tomasov and 
Przemysel as the German infantry fought to break through the Russian frontier 
units. Around Przemysl, the 8th Rifle Corps of Kostenko's 26th Army, tried to 
hold of these attacks, but failed to prevent a crossing of the San River. Late 
in the day Przemysl fell to the Germans, but the 8th three Corps launched an prompt 
counter-attack, preventing the German exploitation of their gains. 
 As 
the day went on, the Germans set up secure bridgeheads over the River Bug so that 
by noon both Walter 
von Reichenau 6th Army and Carl-Heinrich 
von Stülpnagel 17th Army were across the river which had barred their 
advance. Amongst fierce fighting the Soviet border formations gave way to the 
attacks of 3rd Panzer Corps, the 15th Rifle Corps which was on the right flank 
of Potapov's 5th Army collapsed at the joint of the 5th and 4th Armies. Not long 
afterwards, the two armies lost contact. Further German pressure against the joint 
of the 5th and 6th Armies prompted Kirponos the commander of the South West Front 
as the Kiev military district have been redesignated to commit the 22nd and 4th 
Mechanised Corp. Nevertheless, by dusk he was aware of the danger represented 
by the deep advance of Paul 
von Kleist 1st Panzer Group into the northern flank and began the difficult 
task of concentrating his armour to counter the German thrust. The main obstacle 
to the execution of this decision was a complete superiority the Germans had already 
gained in the air.  
 In Africa, The British Royal Air Force (RAF) bombers 
attacked convoy off Libya, damaging one big ship. Night raid on Benghazi.  
 Near East, Enemy shipping at Beirut attacked by the British Royal Air Force 
(RAF) destroyer received direct hit and freighter was set on fire.
