Ordine di battaglia della battaglia della Somme
# Ordine di battaglia della battaglia della Somme

Di seguito è descritto l'ordine di battaglia della battaglia della Somme (1º luglio-18 novembre 1916).

## Forze britanniche e dei Dominion

Nei tipici reggimenti di contea britannici, il 1º e il 2º Battaglione erano formati da soldati regolari, mentre il 3º era il battaglione di riserva speciale che normalmente non serviva oltremare, rimanendo in patria come deposito reggimentale e come centro di addestramento delle unità da cui sarebbero stati presi i rinforzi da inviare ai due battaglioni "operativi". Il 4º, il 5º e il 6º erano normalmente battaglioni impiegati come forze territoriali. I battaglioni territoriali erano identificati come battaglioni di seconda linea e numerati apponendo un "2" prima dell'unità (ad esempio 2/4th battalion). Inizialmente le forze territoriali erano costituite da uomini che non volevano e non potevano essere obbligati a servire oltremare. Il numero di battaglioni dipendeva dal potenziale di reclutamento della zona dalla quale il battaglione veniva arruolato (ad esempio, il Dorsetshire Regiment reclutò 11 battaglioni, mentre il London Regiment riuscì a reclutarne 88).

Le divisioni dell'esercito regolare furono numerate da 1 a 8. Le divisioni arruolate attraverso il piano di reclutamento Kitchener furono numerate da 9 a 26. La 27ª e la 29ª Divisione erano divisioni dell'esercito regolare formate da unità richiamate dalle guarnigioni sparse nell'Impero britannico; quelle dalla 30ª alla 41ª provenivano anch'esse dal New Army, mentre erano divisioni territoriali quelle comprese tra la 42ª e la 74ª. La 63ª Divisione era invece un'unità della Royal Navy, composta da uomini appartenenti alla Riserva navale i cui servigi al momento non erano richiesti in mare.

## Le forze francesi

La maggioranza delle divisioni francesi erano strutturate su tre reggimenti, ognuno dei quali si articolava, a sua volta, in tre battaglioni. Durante la battaglia di Verdun il tenente generale Philippe Pétain aveva fatto ruotare molte divisioni durante lo svolgimento dello scontro e così, sulla Somme, arrivarono molte divisioni che solo lì ricevettero il battesimo del fuoco.
