Furthermore, agreements signed after World War II forbade the stationing on Bornholm or reinforcing of Bornholm, by foreign troops. Therefore, the island was only guarded by one Battle Group with a single active light infantry battalion. However, during the transition to war this Battle Group would have been augmented and reinforced by local reservists.
