had "missed the bus" was especially unfortunate. He was replaced
by Churchill, whose colossal energy, which sometimes burst out as
interference in the detailed conduct of military affairs, helped trans-
form Britain's war effort, stiffen popular resolve to fight on, and,
not least, to strengthen Britain's relationship with the United States.
The third was the acquisition of the Norwegian Merchant Marine
(the world's third largest merchant fleet) for the Allied cause.
The Norwegian campaign served as a matador's cloak for a
far more serious German offensive. Hitler's rapid victory over
Poland in 1939 had caught his planners ill-prepared for an attack
on France and the Low Countries, and their first schemes for
invasion were unenterprising. An attack across the Franco-German
border was clearly ill-advised in view of the fact that the Maginot
Line covered its important sectors. Instead, German planners
proposed to swing widely through Holland and Belgium in an
operation that resembled the Schlieffen Plan of 1914. This did not
appeal to some of those involved, notably Lieutenant General Erich
von Manstein, Chief of Staff to Colonel General von Rundstedt's
Army Group A. Manstein developed a plan intended, as he put it,
"to force a decisive issue by land". It assigned a purely defensive
role to Army Group C, covering the Maginot Line, while Army
Group B, in the north, would move into Holland and Belgium. But
the decisive blow would be struck by Army Group A, which would
contain the bulk of Germany's panzer divisions, and would use them
to break through the French line in the Meuse, just south of the hilly
Ardennes, and would then drive hard for the Channel coast, cutting
the Allied armies in half. The plan horrified some senior officers, one
of whom warned that: "You are cramming a mass of tanks together
in the narrow roads of the Ardennes as if there was no such thing as
air power." However, Hitler approved of it, arguing that the morale
of the French army had been undermined by the vagaries of prewar
politics: it would not withstand a single massive blow.
The Allies had intelligence of initial German plans, whose
security was in any case compromised when a courier carrying a
copy landed, by mistake, in Belgium. Their left wing, including the
BEF and the best mobile elements in the French army, were to move
into Belgium once here neutrality was violated, taking up a position
east of Brussels to block the German advance. Both sides were
numerically evenly matched with 136 divisions, although in the
Allied case this included 22 Belgian and 10 Dutch divisions which
would not be committed until after the Germans had attacked. The
Allies had slightly more tanks than the Germans, and some of them
- like the French Bl heavy tank and Somua S65 - were by no means
contemptible. But the Germans not only enjoyed a clear lead in the
air, but grouped their tanks, with mechanized infantry (panzer
grenadiers) in cohesive panzer divisions. They had the experience of
Poland behind them, and the rise in Germany's fortunes in the late
1930s had helped boost morale.
When the German offensive began on May 10, the Allied left
wing rolled forward, as planned, into Belgium. The Germans staged
several coups de main - the huge Belgian fortress of Eben Emael was
taken by glider troops who landed on top of it - while their
armoured spearhead entered the "impenetrable" Ardennes. It was
bravely but ineffectually opposed by Belgian and French troops, and
reached the Meuse on May 12: an enterprising major general called
Erwin Rommel even got his advance guard across the river that day.
Guderian's panzer corps crossed in strength at Sedan the next day,
and speedily pushed on across France. The French commander-in-
chief, General Maurice Gamelin, in his headquarters at Vincennes,
on the eastern edge of Paris, was consistently wrong-footed.
Although the German high command was far from perfect -
Guderian had a stand-up row with his superior, Kleist - German
tanks reached the Channel coast near Abbeville on May 20.
The German breakthrough left the BEF, Belgian army and part
of the French army encircled in the north. The Belgians, who
actually fought harder than most Anglo-French historians give them
credit for - surrendered on May 28. By this time Lord Gort, the
BEF's commander had taken the courageous decision to evacuate
the BEF through the port of Dunkirk. Although more than one-
third of the troops evacuated were French, the incident soured
Anglo-French relations.
Dunkirk did not end the campaign. The newly-appointed
French Commander-in-Chief, General Maxime Weygand, had done
his unavailing best to cobble together a counterattack into the flanks
