The Battle of Britain

The Hardest Day tests both air forces

On 18 August the Luftwaffe mounted major attacks against Fighter Command targets including Kenley. Low-level and high-level attacks, fighter sweeps and interceptions produced some of the heaviest losses of the campaign on both sides. Kenley's operations facilities were damaged and aircraft were destroyed on the ground and in the air. The fighting also demonstrated the growing vulnerability of the Ju 87 when British fighters penetrated its escort; Stuka units were subsequently withdrawn from the main daylight battle over Britain. The day's significance was not that one side had reached a…

The Butt Report puts a number on the accuracy problem

David Bensusan-Butt circulated his statistical review of Bomber Command's night bombing photographs. He examined roughly 650 usable images from June and July 1941 and compared the photographic evidence with crews' reports that they had attacked their assigned targets. Of aircraft recorded as attacking, only about one in three had come within five miles of the aiming point; over Germany the figure was about one in four and over the Ruhr about one in ten. The report was more severe than those ratios first appear. A five-mile radius enclosed more than…

Battle of Kursk 1943

Operation Kutuzov eliminates the Orel salient

By 18 August German forces had completed their withdrawal from the Orel salient to shorter positions farther west. Western, Bryansk and Central Front attacks had forced a sustained retreat and recovered the territory from which Ninth Army had launched the northern pincer. Kutuzov achieved its territorial objective through a costly series of frontal attacks and armoured commitments. The northern campaign had moved far beyond the limited ground gained by Ninth Army during Citadel, while the southern Soviet offensive was still fighting for Kharkov.

Operation Dragoon

Truscott improvises Task Force Butler

Truscott had no armoured division to exploit with, so he made one. Task Force Butler was assembled from a reconnaissance squadron, a tank battalion, a battalion of armoured infantry, a field artillery battalion and a tank destroyer company, under Brigadier General Frederick Butler. Its orders were to drive north into the interior and reach the Rhône valley ahead of the retreating Nineteenth Army. It set off on 18 August through country that had been in Resistance hands for weeks.

Rol-Tanguy orders general mobilisation

Colonel Henri Rol-Tanguy, commanding the FFI in the Île-de-France, had posters printed calling every Parisian capable of bearing arms to mobilise. His command post was in a disused tunnel beneath the Place Denfert-Rochereau, connected to the surface by the city telephone system the Germans never cut. The order was issued without waiting for agreement from de Gaulle's delegates, who wanted the rising held back until the Allies were closer. That disagreement ran through the whole week.
