620,000 Allied; 500,000 Germans
Casualties on the first day of the Somme
60,000 British casualties; 20,000 dead
Tactics before the Somme
Preliminary bombardment for week prior to battle, intended to drive Germans from trenches and eliminate opposition; 1.7 million shells fired but many failed to explode; German trenches heavily fortified
How many shells were fired in the week before the Somme?
1.7 million
What happened on the first day of the Somme?
18 Allied divisions walked across no-man’s land in extended fire; 100 German machine-gun nests awaited; any unit which reached German trenches were driven back
What percentage of officers were killed on the first day of the Somme?
60%
When were tanks used for the first time?
15th September-Battle of Flers-Courcette, a subsidiary attack of the Somme
New tactics developed during the Somme
Creeping barrage used at the Battle of Bazentin Ridge–great emphasis placed on element of surprise; troops advanced in darkness; German surprised by brevity of bombardment and proximity of attacking waves–successful capture of German position but Allies too weak to advance
When was the Battle of Passchendaele (3rd Ypres)
31st July-6th November 1917
What was Passchendaele
The major British offensive in Flanders in 1917
What was the aim of Passchendaele
A decisive breakthrough, capturing Passchendaele Ridge then taking control of German-occupied channel ports, allowing the Allies to eliminate Ostend and Zeebrugge U-boat bases
What was the result of Passchendaele
Ended with the capture of Passchendaele village; advance of 8km
What were the casualties of Passchendaele
275,000 Allied; 200,000 German
What preceded Passchendaele?
Heavy artillery barrage and heavy shelling; 4.5 million shells fired in 10 days prior to attack
What was the consequence of heavy shelling at Passchendaele?
4.5 million shells fired in 10 days prior to attack; created shell holes which filled with water and became muddy due to heavy rain; made it difficult for soldiers to advance as they struggled through heavy mud, highly exposed
What was the distance between trenches?
Not the same distance along front; no man’s land 8-10 km in some place,s 50 m in others
What were opposing trenches separated by?
Opposing trenches separated by no-man’s land
What was it like in no-man’s land?
Usually deep craters (mud, heavy rain, artillery bombardment–>quagmire), often mined, difficulties fighting/walking-Passchendaele
How many lines of trenches were there, and what were they called?
Usually 3 lines; front line, support, and reserve, linked by communications trenches which enabled movement out of enemy’s sight
What was the support line for?
The line where soldiers, if possible, retreated during bombardment. Rear wall of support line contained dugouts
How long did soldiers spend in each line?
For British, men in firing line 15% of time, support trench 10%, reserve trench 10%, out of trenches for all other periods (other duties, rest+rec, leave)
How many men were there in the front lines of the Allied forces?
10% of a division at any time (1 division was 20,000 men)
What formation were trenches built in?
Zigzag formation
Why were trenches built in zig zag formation?
Defensive measure–minimised impact of shell landing in the trench, preventing attackers from having a clear line of fire
What was located between lines of trenches?
Around 35m of barbed wire-the average soldier could throw a grenade to 30m; if one line was overrun, the next line could take on the front line’s role
What did soldiers often do as night activities?
Repairing barbed wire defences, sabotaging enemy’s defences with wire cutters
What was the structure of front line trenches?
Fire step, where could fire at attacking soldier; metre-thick layer of protective sandbags in front; behind them was the parados, which prevented them from being shot by those in support trenches, prevented troops from being silhouetted against skyline in daylight/when going OTT. Duckboards aimed to provide firm footing.
How were trenches reinforced?
Sandbags, timber, corrugated iron
