The United states 5th Infantry Division (Mechanized) jumped
off on its raid on June 19th from Chojnice and Czluchow in a converging drive on
the Bydoszcz and Torun area. Contact was made with partisans of the 2nd
Polish Free Legion in Tuchola, and they reported the road ahead clear.
Guides were provided and on the 21st advanced elements of the division had
reached Torun, with follow-up forces closing up. Only scattered resistance
from local militia had been encountered. The division spent a week in the
Torun area distilling fuel in anticipation of the second bound. One June
29th it moved south on the road to Wloclawek, which the division's recon
battalion (4th squadron of the 12th Cavalry, mounted on horseback) had scouted
as far south as Krosniewice. The division closed up Wloclawek by the
evening of June 30th and advanced elements were in the strategic road junction
of Krosniewice by July 1st.
The division again paused for maintenance and fuel
distillation while the cavalry scouted south. On July 3rd, the 4-12
Cavalry reported a strong blocking position in front of Lodz at the town of
Zgierz. Interrogation of prisoners revealed the blocking force to be the
Polish 6th Border Guard Brigade. The division commander ordered the
division's 256th Mechanized Brigade (Louisiana National Guard) to deploy against
the blocking position while the 4-12 made a wide turning movement through Kolo,
Uniejow, Szadel and Lask to hit Lodz from the southwest. The division's
1st Brigade consolidated the division base camp area at Krosniewice, while the
division's 2nd Brigade was pushed west toward Konin to guard against a possible
counterattack by the 1st Polish Tank Army, known to be in the Poznan area.
July 9th:
The 4-12 Cavalry reported by radio that it had encountered Polish cavalry in
superior strength at the town of Pabiance, a few kilometers south of Lodz, and
that it was falling back to Lask. Later, outposts of the 2nd Brigade
guarding the road bridge across the Warta River at Konin successfully resisted
an attack by mechanized troops identified as elements of the Polish 10th Tank
Division. The Polish troops withdrew, but could be seen digging in several
kilometers from the bridge.
July 10th: The division commander
ordered the 3-11 Infantry of the 1st Brigade, then in Kutno, to move out east
toward Lowice to develop and attack from the northeast against Lodz. At
the same time he ordered the 256th Brigade at Ozorkow to detach a battalion and
move it overland south of Uniejow in preparation to support the 4-12 Cavalry.
Almost immediately, the 3-11 Infantry from Kutnow encountered advancing mounted
troops in superior numbers and was driven back to Kutno under heavy pressure.
By evening, 3-11 Infantry had determined it was facing advanced elements of the
Soviet 89th Cavalry Division (formerly the 89th Motorized Rifle Division), which
had last been indentified as being deep in Byelorussia. 4-12 Cavalry had
identified its antagonist as the Polish 11th Border Guard Brigade, formerly at
Lublin.
July 11th: German Third Army reported
by radio that it was under attack by strong cavalry and mechanized forces from
the Pila area, and had identified elements of the 1st Polish Tank Army. It
also reported the Torun area had been overrun by elements of the Soviet 22nd
Cavalry Army from Byelorussia. The division commander held an afternoon
conference with his Brigade commanders and staff and decided the division should
attempt to break out through Lodz and then drive east through Piotrkow and Radom
to be positioned for a drive north. This would avoid the major enemy troop
concentrations, cause maximum damage to the lines of communications of the
newly-committed 22nd Cavalry Army, and leave the door open for a possible
link-up with troops of the northern Baltic coast. Accordingly, 256th
Brigade began shifting southwest toward Szadel while 1st Brigade took over the
position at Ozorkow.
July 12th and 13th: Little enemy
resistance was encountered, and all units successfully completed their planned
movements.
July 14th: The 1st and 256th Brigades
began their attacks on Lodz, and immediately encountered stronger resistance
than had been anticipated. The right-hand attack by 256th Brigade along
the Lask-Pabiance road brushed aside outlying cavalry pickets, but then
encountered entrenched and well-equipped infantry in front of Pabiance.
After several of the brigade's remaining tanks and infantry fighting vehicles
had been knocked out, the brigade paused to regroup. Within an hour,
however, the brigade was struck in the flank by tanks and armored personnel
carriers advancing from Piotrkow and was pushed back to Lask. 1st
Brigade's attack had encountered dug-in tanks of the Soviet 20th Tank Division
as soon as it crossed its start line and had made no progress all day. The
20th Tank Division had last been reported in the Ukraine as an element of the
4th Guards Tank Army. At midday, the 2nd Brigade's 3-77 Armored at Kolo
was probed by Polish mechanized forces, and the division rearguard at Kosniewice
came under attack by the Soviet 96th Cavalry Division.
By nightfall it was apparent there had either been a major
intelligence failure or the Warsaw Pact had succeeded in moving up reserve
formations with more speed than anyone had anticipated. It was also clear
that, rather than making headway toward a breakout, the 5th Division was badly
scattered and hard pressed on all fronts. The division commander decided
that it was time to concentrate and attempt to get some room to maneuver.
The division would move west toward Kalisz. 2nd Brigade would remain
roughly in place, with the 3-77 Armored holding Kolo as a bridgehead across the
Warta River. 1st Brigade and the division command would move overland to
Uniejow. A battalion would hold the river crossing while the main body
moved into reserve across the river. 256th Brigade was to fall back along
the road to Sieradz and hold the Warta River crossing there.
July 15th: In the morning the 1st
Brigade brigade began its withdrawal but was hit by the Soviet 20th Tank
division while moving across the open ground to Uniejow. By afternoon,
over a dozen Soviet tanks were burning and the 20th Tank Division had been
driven back badly mauled. 2-11 Infantry, however, had been overrun at
Kutno. A badly-depleted brigade limped into Uniejow by nightfall, only to
find the bridge across the Warta blown. The 2th Engineer Battalion began
rebuilding the bridge by torchlight with what local materials it could find.
256th Brigade's main body remained in Lask all day due to lack of fuel, but 4-12
Cavalry moved back and secured Sieradz and the Warta River bridge there.
1st Brigade, with the 3-143 Infantry at Konin and the 3-77 Armored at Kolo, sent
its remaining battalion, 1-40 Armored, south to Kalisz to secure the division
rear area.
July 16th: The division's situation
began deteriorating rapidly. 256th Brigade at Lask was hit hard from the
east and northeast by strong mechanized forces and the brigade headquarters was
orrun. Still short of fuel, most of the brigade's tanks fought and died in
place, and surviving personnel broke out on foot into the woods to the
southwest. The attacking force was identified as the Soviet 124th
Motorized Rifle Division, another component of the 4th Guards Tank Army.
At the same time the 256th Brigade was being overrun, advanced elements of the
Soviet 21st Motorized Rifle Division appeared behind the 4-12 Cavalry's
positions at Sieradz, having approached on the road from Zloczew. This was
yet another division of the 4th Guards Tank Army. 4-12 Cavalry, by now
reduced to only 200 troopers, withdrew up the road to Kalisz.
By late afternoon, the 1-40 Armored of the 1st Brigade at
Kalisz was pushing back infantry probes from the direction of Pleszew to the
west and Ostrow to the southwest. The bridge at Uniejow was completed by
late morning and 1st Brigade began bringing across its heavy equipment.
Polish cavalry from the west was cautiously probing 1st Brigade's positions at
the crossing point.
That evening, the division commander ordered all elements of
the division to blow the Warta River bridges and concentrate at Kalisz.
While this was possible at Konin, Kolo and Uniejow, the bridge at Sieradz had
already fallen and the 21st Motor Rifle Division had crossed further south at
Wielun, in any event.
July 17th: By daybreak, the pressure on
1-40 Armored, by now joined by the remnants of 4-12 Cavalry, was mounting.
Polish infantry from Pleszew was now being joined by light armored vehicles
believed to be from the 10th Polish Tank Division. The infantry at Ostrow
had been identified as elements of the Soviet 12th Guards Tank Division, a weak
formation which had been in reserve near Legnica. However, it was now
being joined by mechanized vehicles believed to belong to the 21st Motorized
Rifle Division. At midday, advanced pickets of the 4-12 Cavalry reported a
large mechanized column advancing up the road from Sieradz toward Kalisz.
1-40 Armored was beginning to strain under the pressure from the west and
southwest and couldn't spare any troops for the new threat.
Advanced elements of the 1st Brigade were approaching from the
north, however, and the remaining 10 M1E2s of 3-70 armor turned south off the
road between Kalisz and Turek and advanced overland to take the Soviet column in
flank. 2-21 Field Artillery pulled its six howitzers off the road behind
them and set up to deliver supporting fires. 3-10 Infantry, mostly in
trucks, would follow up to support the tanks.
3-70 Armored reached a position two kilometers north of the
road at 1100 hours with nothing left in its fuel tanks but fumes. Taking
up defilade positions atop a low rise, the battalion commander saw the main body
of the Soviet 124th Motor Rifle Division stretched out on the road below him.
At 1110 hours the battalion opened fire and immediately began registering hits
along the length of the column. Soon the column was covered in dense black
smoke from burning vehicles, through which the tankers could see numerous
secondary explosions as ammo vehicles went up.
At 1220 hours the Soviets were counterattacking, but several
attempts to storm the position by tanks and armored personnel carriers were
broken up, and the 2000 meters of open ground between 3-70 Armored's position
and the road became littered with the wrecks of most of the Soviet division's
remaining armor. A late afternoon attempt to outflank the position was
thwarted by the arrival of 3-10 Infantry.
As night fell, the division commander took stock of the
situation. 1st Brigade, with 3-70 Armored and 3-10 Infantry, was on the
left overlooking the Sieradz road. 4-12 Cavalry and 1-40 Armored were
holding Kalisz. 3-143 Infantry of 2nd Brigade was in the woods north of
Kalisz on the road to Konin, guarding the division's right, while 2nd Brigade's
3-77 Armored formed a small division reserve just behind Kalisz. 3-19
Field Artillery was deployed with 3-77 Armored, while 2-21 Field Artillery was
still several kilometers to the northeast, along with most of the division
supply and maintenance echelon.
The Soviet 124th Motor Rifle Division had been shattered on
the Sieradz road, but pressure was building from the Soviet 21st Motor Rifle
Division at Ostrow and the Polish 10th Tank Division at Pleszew. Rearguard
parties were reporting increased activity along the Warta River line behind the
division, and the remnants of the Soviet 20th Tank Division were still out there
somewhere.
The division commander decided on a breakout to the south,
exploiting the damage 1st Brigade had handed to the 124th Motor Rifles the day
before. The division's emergency fuel reserve would be dispersed to the
units, everyone would top off and draw as many rations and as much ammo as they
could carry. Supply and maintenance parties would split up and attach
themselves to the nearest combat unit and follow them out.
2nd Brigade would spearhead with the 3-77 Armored and 3-143
Infantry (moved down by night from the north), driving south by southeast from
behind Kalisz. 1st Brigade would cover its left flank with a drive south
from its blocking position. The division artillery would put every
available round on Ostrow to break up any potential attack from the 21st Motor
Rifles. 4-12 Cavalry would follow up the 2nd Brigade and work its way into
the woods between Ostrow and Ostrzeszow to cover the right flank. 1-40
Armored would hold Kalisz until the remaining elements of the division had moved
south, and then fight a delaying action against pursuit. Considering the
odds, the chances of success were slim, but it was the only show in town.
As it happened, the 21st Motorized Rifle Division and the
Polish 10th Tank Division struck first. The attack came in hard three
hours before dawn, using infrared lights. 1-61 Infantry had already
pulled out of its blocking position north of Kalisz and was in road march
passing through the crossroads when the first artillery rounds began falling on
the town. 1-40 Armored holding the perimeter had the advantage of being in
place and its thermal sights were less affected by the smoke that soon covered
everything than were the Soviet IR lights. But 10th Polish Tank Division's
attack hit empty positions, and within a hour they were behind Kalisz in the
division rear. Shortly before sunup, Polish armored vehicles entered the
division headquarters area. The division commander radioed in the clear to
all units, "Good luck. You're in your own, now."
