to 20 times (21). The expansion of the army has brought difficulties to supplies. During the Thirty Years' War, France, Sweden, the Holy Roman Empire, etc. all invested more than 30,000 troops, while Russia's troops in Livonia

130,000 troops were used in the war. As the number of people increased, the logistics and supply tasks would inevitably increase accordingly. Especially in a protracted siege, once the siege cannot be conquered for a long time, supply and logistics will become a big problem. The army uses robbery as supplies.

It has always been a tradition, but in a war with a huge number of people, it is outdated and unwise to rely solely on robbery for supplies. If the area to be attacked cannot be conquered for a long time due to the high walls and high walls, and the defenders have strong walls and clear fields, it is not wise to rely solely on robbery for supplies.

Quite difficult. In the Thirty Years' War, one of the reasons why Gustav's army succeeded cannot be ignored is that it had better logistics supplies. Isabella also did a good job when conquering Granada.

It ensured logistics and provided a strong guarantee for the capture of Granada. On the contrary, during the Thirty Years' War, Valentans' "Locust Swarm" adopted the policy of "fighting to support war", which should be regarded as a typical example.

(twenty two).

Firearms equipped troops have led to major changes in traditional logistics supply. The baggage has increased greatly, making logistics supply no longer just a matter of food and grass. During this period, with the application of firearms, logistics supply faced more problems and tasks became more complex.

It is arduous and heavy. Horses are not only used for cavalry, but also for carrying artillery. For example, a Spanish artillery requires 25 horses to carry. In wars, battles are often defeated due to supply problems. In 1557

King Philip II of Spain commanded the army and could have marched directly to Paris and occupied France. However, at the critical moment, he gave up the victory that was within easy reach. The reason was that the cost of logistical support was too high, his talents were insufficient, and victory could not be achieved. The cost of the war was also too high.

Due to the increasing use of firearms, war cannot be fought without money (23). The increase in the cost of war is reflected in two aspects. On the one hand, the attacking party has to pay a heavy price (human, material and financial resources); on the other hand, due to

It is highly destructive and causes huge losses to the enemy. War has become a struggle for strength, goods and money, which puts forward higher requirements for logistical support. The importance of logistical support is therefore more prominent, so people in war

More emphasis is placed on logistics work than in the past. Military logistics has entered a new historical period with the application of firearms.

The impact of gunpowder and firearms on Europe is multi-level and multi-faceted. It has contributed to the great progress of military civilization. The progress of military civilization is multi-faceted, but the promotion of gunpowder and firearms is unparalleled by other factors. In this kind of
