Report No.4
Air Attacks on Enemy Tanks and Motor Transport in the Mortain Area, August 1944
Tactical Situation
1. At the beginning of August 1944, the Allied armies had begun their break out from the Normandy beach head; the British and Canadians were pushing southward from CAUMONT and CAEN and the Americans, having driven down the west coast of Normandy, were rapidly moving eastward and northwards thereby threatening to surround the German armies in Normandy.
2. The following diary of events in the MORTAIN area illustrates the circumstances in which the air attacks took place:
6 Aug. During the day the enemy counter attacked strongly against 30 Inf. Div in the MORTAIN area and they re occupied the town.
7 Aug. In the early morning the enemy launched a strong armoured attack in the MORTAIN area. Although small numbers of tanks penetrated U.S. positions at a few points, the situation was soon under control. During the day large enemy concentrations of tanks and MT were attacked from the air with excellent results.
8 Aug. Little change reported. Enemy still exerted pressure in the MORTAIN area.
9 Aug. The enemy continued his efforts to break through to Avranches with the greater part of his armoured formations. Although the enemy held MORTAIN, 4, 9 and 30 Inf. Divs. with 2 and 3 Armd. Divs. resisted strongly on the high ground to the north, west and south of the town. 35 Inf. Div. made some progress with an attack SW of MORTAIN.
10 Aug. SE of MORTAIN 2 Armd. Div. made progress, reaching a point 6 miles east of the town. Heavy concentrations of enemy armour (5 divisions) remained in the MORTAIN DOMFRONT area but no large scale counter attacks developed. 4, 9 and 30 Inf. Divs. continued to meet heavy opposition.
11 Aug. The enemy withdrew from the MORTAIN salient and the town was re occupied by troops of VII Corps. North and south of the town all divisions advanced against little or no opposition.
Air Effort
3. Bad weather prevented flying in the morning of 7 August but arrangements were made for the Second Tactical Air Force to come to the assistance of the IX US Air Force as soon as conditions permitted. The weather cleared quite suddenly about mid day, between which time and dusk 294 sorties were flown by typhoons of 2 TAF in support of the American ground forces in the MORTAIN area. Although, owing to their many other commitments in France, the IX USAAF only flew some 200 sorties to MORTAIN that afternoon, they continued their attacks over the next three days and flew 441 sorties in all.
4. Conditions on the afternoon of 7 August were ideal from the pilot's point of view as no opposition was encountered from enemy aircraft nor, till late in the day, was there any appreciable flak reaction. Under cover of mist and low cloud the Germans seemed to have neglected all normal precautions and, when the weather cleared, they were sighted in large numbers head to tail in narrow roads and lanes. The pilots reported that they were able to go in very close to attack, rockets being fired at 1000 yards range and cannon and machine guns from even closer. Claims made by the pilots during the MORTAIN Battle (7th 10th August) are shown in Table 1 below:

Ground Investigation
5. Between 12 August and 20 August members of the Operational Research Sections from 21 Army Group and Second Tactical Air Force conducted separate ground investigations of the battle area around MORTAIN (see map at Appendix A). The results of the two investigations were compared and collated to produce the figures shown in Table II. (See opposite page)
6. It was not possible to discriminate between the victims of IX USAAF and of' 2 TAF because, although the 500 lb bomb was the favourite weapon of the former and the rocket that of the latter, American pilots fired some 600 rockets in the course of these attacks and British pilots dropped some bombs. The respective merits of the 50 calibre MG and the 20 mm cannon were not considered and all vehicles that had been destroyed by small projectiles fired from the air have been classed as "Cannon or MG."
7. Tanks and other vehicles classed as "abandoned" have not been included in the Air Total in Table 11 because, although they were probably abandoned as a result of air attack, they can hardly be considered to have been among those which the pilots claimed to have destroyed as such claims are generally supported by mentions of fire or explosion.
8. Similarly those enemy vehicles listed as "destroyed by crew" may be regarded as indirect victims of air attack but cannot justifiably be taken into consideration when comparing pilots' claims with what was found on the battlefield.
9. It is most unlikely that all of the unknown causes were due to air attack, particularly as many of them were found at considerable distances from the nearest signs of such attack and as ground forces were also fighting fierce battles in this area. However, if all the "Unknown causes" are added to the air totals, the resultant figures (armour, 21 + 15 = 36 and MT, 12 + 26 = 3

are still only about a quarter of the numbers claimed as destroyed by the air forces.
10. The area was not very extensive and as two teams were searching it over a period of several days it is not considered that any appreciable number vehicles was missed. This is confirmed by the fact that one of the investigators flew low over the area in an Auster, plotting the positions of vehicles seen from the air; no fresh vehicles were discovered by this means.
11. The efficiency of the German recovery system has been put forward as an explanation of the large discrepancy between the number of vehicles claimed to be destroyed and the actual numbers found. Tanks and lorries that are destroyed as a result of air attack are almost always burnt out and would not be worth salvaging unless time and labour were both plentiful. Many prisoners have been questioned on the subject of the recovery of tanks and it has been established that burnt out tanks are never salvaged. In addition it has been ascertained that, contrary to certain statements made about the MORTAIN battle, very little recovery was done in this part of Normandy at the time, in fact the repair and recovery teams were already pulling out of Normandy when the Battle of Mortain was at its height. In any case before considering the recovery of the "destroyed" tanks and MT, the "probably destroyed" (43 tanks and 20 MT) and the "damaged" (56 tanks and 60 MT) must have presented the recovery organisation with a large task without counting any that may have been damaged by the ground forces.
12. At Appendix B is a list of the vehicles found by members of No.2 Operational Research Section together with the causes of destruction where it was possible to assess them. No similar record is available for the vehicles which were examined only by members of ORS/2 TAF.
Conclusions
(a) The attacks by the Allied Air Forces had a considerable effect on the enemy's unsuccessful counter attack at MORTAIN.
(b) The number of vehicles claimed by the pilots as "destroyed" was about four times the actual number discovered.
(c) A number of vehicles, though not claimed by the pilots, were lost to the enemy by "indirect" air action (i.e. abandoned or destroyed by the crew).
Appendix B
1. Road Juvigny Le Tertre to St. Barthelmy
At pt 565145
2 Panthers
(a) AP shot above track on LHS of hull penetrated and killed some of crew. Gun, tracks, engine and petrol all O.K. No fire. Abandoned after AP hit but probably driven off road first.
(b) 105 mm HE ? strike 2 ft up from hull on LH rear corner of turret. Fragments damaged cupola and periscopes; also top hull plate torn (L shape 10” x 6”) just below strike: engine air louvres damaged.
Also 75 AP hit through bogies on LH side. Engine O.K. petrol O.K., gun O.K. Deep scoop by 75 AP on rear. Abandoned by crew unharmed: no bodies, no gore. There were 4 RP strikes in field on other side of road and one on this side hit tree at roadside.
Next field, same side of road
2 Panthers
(a) No visible sign of damage. Petrol, engine, tracks and gun all O.K. Even sights left on gun. Abandoned undamaged.
(b) Hit by 75 AP on LHSjust below turret in ammunition storage. Brewed up. Also hit on RH track and sprocket. None of these hits could have been from air.
Field north side of road, same place
3 Panthers, 1 Armd Car, 1 Armd Tp Carrier
(a) Panther received slanting blow into track and bogies on RHS. Definite RP hit as proved by debris but poor explosion as shown by small damage. Everything else in the tank quite O.K.
(b) Panther received 4 hits from 75 min AP (3 scooped and 1 penetrated) on underside of front, almost belly. This can only be exposed when climbing bank. Terrific brew up yet tyres on LHS untouched.
(c) Panther had 4 75 mm AP scoops on front glacis plate. Gun, engine, petrol and tracks all O.K. Deserted intact.
(d) Armd Car. RP crater and debris below RH front wheel; explosive force upwards and inwards. Brewed up.
(e) Armd Tp Carrier had 105 mm AP hit on LHS and was completed brewed up.
On N side of road, few yards further east.
Panther RP strike under rear had blown petrol tank and caused brew up.
At point 568147 in lane
Panther with two huge holes in turret from above. Also hit on leading edge of front glacis plate (probably RP). 2 75 AP scoops one on glacis and other on mantlet. Major damage (holes in turret) might have been RP but several bomb craters (500 lb.025 sec delay) within 15 yds suggest possible direct hit by bomb. Complete write off.
Few yards east along road
Armd Tp Carrier complete wreck as amn exploded and blew side off. Brew up from unknown causes.
Other side of road, same ref.
Panther RP strikes all along road but bazooka hit on LHS into amn stowage space caused brew up. Angle of attack suggests infantryman fired from high bank on roadside at almost point blank range could have been after desertion.
30 yds further east
2 Armd Tp Carriers, 1 Peoples Car (Amphibious)
(a) Arrad Tp Carrier with RP craters all round it. Complete wreck; looks like RP hit on RH rear corner.
(b) Armd Tp Carrier with downward strike through side armour and then floor. Almost definite RP.

Orchard W of cross roads
Ambulance and Armd Tp Carrier
(a) Ambulance peppered with fragments and abandoned.
(b) Armd Tp Carrier unknown causes brew up.
At cross roads 575144
Panther holes in floor over track which suggested downward attack but no possible entry for hit, therefore caused by explosion of gun. Unknown causes for brew up (possibly by crew).
2. Road from Cherence le Roussel via St. Barthelamy to Mortain
