We saw in Part 3 how the USAAF’s 301st Bombardment Group transformed Chelveston into an operational heavy-bomber station, launching their first combat missions over Europe. Early operations brought the group face-to-face with enemy fighters, resulting in casualties and dramatic incidents, including a heavily damaged B-17 returning to RAF Gatwick and another ditching in the Channel. By late November, the 301st had departed for North Africa, leaving Chelveston ready to welcome its next unit, the 305th Bombardment Group.
These early battles gave great hope for the men of the 8th Air Force, with low losses they were perhaps, lured into a false sense of security and feelings of an easy battle ahead. But all that was to be washed away, when over the coming months, the 8th would become battle hardened and severely scarred.
Forging the ‘Can-Do’ Group: Col. Curtis LeMay and the 305th Bombardment Group
The 305th, who arrived here in early December 1942, were led by the tough and innovative Col. Curtis LeMay whose drive and leadership led to the rookie 305th, being known as the ‘Can do’ Group.
LeMay was a very quiet man, but commanded respect from those beneath him. He was slightly forgiving, but he would not tolerate being lied to. LeMay, never having been in battle himself, forged his career in the United States where he learnt every detail of the B-17, the bomber he was about to take to war. LeMay looked to the likes of Col. Armstrong for guidance, asking him question after question about his experiences and tactics, absorbing his advise like a sponge. Many of Armstrong’s answers he took strictly at face value, however, only to realise later, that perhaps Armstrong was not the man LeMay thought he was.
Through his leadership style, LeMay earned the title of ‘Iron Ass’, a grudging respect from those who followed him. The 305th, led by LeMay, would be a forward thinking group, one who would go on to develop pioneering methods of aerial bombing and battle formation flying.
The heavy armament of the B-17 gave the highest level of protection when in a tight formation, each gun covering a wide arc thus protecting all the others in the group. By forming a ‘box’, this level of protection was at its highest, a style developed by the 305th. With bombing accuracy becoming a major issue for the USAAF, the idea of a lead crew, was another idea stemming from the experiences of the 305th and LeMay. By having a single lead upon whom the whole formation would bomb, accuracy was improved and concentrations of bombs in the target area increased. Both these methods became standard operating procedures throughout the 8th Air Force during the Second World War.
The 305th like the 301st before them, and now their sister squadron the 306th at Thurleigh, were amongst the first few units to arrive in the UK, and as newbies with no battle experience, they faced an incredibly long and steep learning curve.
The 305th arrived in the UK forming initially at RAF Grafton Underwood around September 12th, 1942, bringing together both the ground and air echelons as they prepared to commence operations over Europe. The mud and cold that greeted them would quickly become their bed-partner, remaining with them for the duration of their wartime lives.
The conditions at Grafton were appalling and the airfield was totally unfit for a bomber unit. It would take an enormous amount of upgrading and huge renovations to improve it. This would mean the newly arrived 305th would have to move out, a move that signalled the beginning of their time at Chelveston. Over the Period 6th to 11th December, they transferred across, a temporary measure that quickly became permanent lasting the duration of the war.
Their journey to Chelveston began back at Salt Lake City where they were activated on March 1st 1942. They spent a large part of their training at Muroc Lake Air base (now Edwards Air Force base) before the ground echelon sailed on Queen Mary in early September, arriving at Greenock on 12th. The air echelon meanwhile didn’t leave until October, advanced flight training taking place at Syracuse, New York, in the weeks prior to their departure. Flying the usual northern route they brought their B-17Fs via Presque Isle, Gander and Prestwick, before routing to Grafton underwood.
Following Roosevelt’s controversial slimming down of the Eighth, the 305th, together with the 91st, 303rd and 306th, formed the only B-17 groups remaining in the command, while the 44th and 93rd were its sole B-24 units. Collectively, they constituted the backbone of an Eighth Air Force, stripped to little more than this handful of operational groups – a striking force reduced to a shadow of its intended strength. But then, even that would be cut back, with elements of the B-24s being sent to North Africa as well, and not returning to the UK until the following summer after which time, the B-17s had ‘flown the US’s flag’ over occupied Europe.
Fearing that heavy losses would catastrophically reduce the remaining groups to a handful of aircraft and crews, Spatz and Eaker mounted relatively ‘safe’ operations, those featuring little penetration into the European stronghold. However, the chances of loses, even at those short distances, continued to remain high.
Tactics and Innovation: The 305th’s Early Combat Lessons
The 305th’s first mission would happen a month after their arrival at Grafton on 17th November 1942 against the U-boat pens at St. Nazaire. It was during these early missions that the Luftwaffe pilots worked out that a full frontal attack on a B-17 would target it’s weakest point – a blind spot in the gunners forward arc. Here, the fighters had both a better chance of survival and the ability to cripple an aircraft by killing both its pilot and co-pilot in a well aimed attack.
To combat this weakness. two innovative Thurleigh ground crew devised a method by which the nose guns could be moved and supported thus filling the gap in the arc. After developing and trialling the new fixture, the system quickly became standard fittings on later B-17s across the air force.
For the 305th, the otherwise fierce attack of 17th November proved a rare exception: they returned without a single casualty – one of only a handful of units to do so – despite nearly a quarter of the dispatched aircraft sustaining damage from concentrated machine-gun and cannon fire.
These early battles highlighted a stark reality: losses and damage were disproportionately high when set against the relatively small numbers of aircraft taking part. LeMay, latched onto this, and quickly became the driving force behind efforts to improve both survival and bombing effectiveness.
After being told by Armstrong never to fly straight and level for more than a few seconds on the bomb run, LeMay did exactly the opposite, leading his group for some 4 minutes toward the target. Whilst this tactic was indeed a gamble, the 305th’s bombing record was soon to be far in excess of other groups especially those who followed the Armstrong doctrine.
LeMay, encouraged by these successes, also began experimenting with new combat formations, seeking a balance between maximising defensive firepower and reducing the risk of bombers damaging one another in the chaos of fighter attacks. His solution was the development of the staggered ‘box’ formation, arranged both vertically and horizontally. To preserve bombing accuracy and avoid aircraft jostling for position, all bombers would release their loads simultaneously on the lead aircraft’s command. These methods proved to be so effective that they were also quickly adopted as standard practice throughout the entire Eighth Air Force.
In the next part of Chelveston’s history, we see the 305th pushed to the limits of courage and endurance, facing punishing winter raids over the U-boat pens and the heart of Germany. Crews battled flak, fighters, freezing conditions, and the strain of inexperienced personnel, while stories of survival, heroism, and narrow escapes emerged from each mission. Just as morale teetered under the weight of losses, the airfield itself was officially handed over to full American control – yet even this milestone could not prepare them for the next series of deadly operations that would test the 305th like never before.
