Costs, Casualties and Other Data

World War II spread death and devastation throughout most of the world to an extent never before experienced. The loss of life can be only generally summarized; an attempt to express the value of property and livelihoods destroyed in terms of money is futile: the resulting sums reach astronomical figures that have little if any practical meaning.

Military Casualties

Probably the best documented and most meaningful figures are the battle casualties. Those for the United States, Great Britain, and the Commonwealth nations are accurate; those for other nations, Allied or Axis, vary in reliability. Chinese figures are largely estimates because of the lack of documentation, information on Soviet losses has been given only grudgingly and in very general terms, and many records of the Axis nations were lost when those countries were overrun. The most accurate available figures are shown in Tables 1, 2, 3 & 4.

In utilizing strength figures, it should be noted that total strength means the total number of personnel belonging to the armed forces during the entire war, whereas peak strength is the greatest strength reached at any one time during the war. Several methods of classifying and computing casualties are in use, and other variations result from the differing periods covered by the various computations. Consequently, different reputable reference works sometimes show slightly different figures even for United States casualties. Non-battle deaths include deaths from accidents and disease.

Civilian Casualties

Casualties among civilians were much less accurately recorded than military losses. In part, this was unavoidable because of the population shifts that took place as civilians fled before invading armies or the continual air attacks on major industrial centers, or were sent to Germany or the Soviet Union for forced labor.

Civilian casualties in the United Kingdom, slightly over half of which were inflicted in the London area, were as follows:


                    Killed    Seriously injured    Total
Aircraft bombs      51,509          61,423        112,932
V-1 (flying bombs)   6,184          17,981         24,165
V-2                  2,754           6,523          9,277
Artillery fire         148             255            403
---------------------------------------------------------------
Total               60,595          86,182        146,777

Civilian casualties in the USSR have been placed roughly at 2,500,000 killed. The loss of population (including both military and civilian casualties) caused directly or indirectly by the war has been stated at 20,000,000. Air raids against Germany killed approximately 300,000 Germans and seriously injured about 780,000 more. Numerous additional casualties occurred during the Soviet invasion of 1944-1945, but no specific estimates are available. Japanese civilian casualties probably approached 500,000 killed and 625,000 seriously injured, plus a considerable number reported as missing after the fire raids and atomic bombings. In addition, about 360,000 Japanese captured by the Russians in Manchuria, Korea, and the Kuril Islands were still missing in 1950; a large number of them have never been accounted for. Chinese civilian losses are unknown but probably numbered several million.

Industrial Conversion and War Production

In the final analysis, victory was won by the Allied powers' technological superiority--the ability to raise, arm, equip, move, and supply superior forces throughout the world, and through them to break up and destroy the technological resources (as well as much of the armed forces) of the Axis nations. Of all the Allies, it was the United States that possessed the raw materials, skilled manpower, and industries that made their victory possible. This potential American technological power, however, required precious time to change from peacetime to military production. The process of conversion, and of reconversion at the war's end, is illustrated in Table 4.

Among the varied items purchased by United States defense expenditures were 57,027 medium tanks (9 different types), 676,433 two-and-one-half-ton, six-wheel-drive trucks (11 types), 1,054 eight-inch howitzers (48 of them self-propelled), 476,628 2.36-inch rocket launchers (bazookas), 4,014,731 Garand rifles, 106,658 gunner's quadrants, 4,072,000,000 rounds of .45-caliber ammunition, 57,488,000 wool undershirts, 116,000,000 pounds of peanut butter, 206,753 SCR-536 (Handie-Talkie) radio sets, 500,754 30-dose bottles of influenza virus vaccine, 7,570 locomotives (48 types), 23,510,030 military gas masks (2 types), and 3,898 B-29 (Superfortress) very heavy bombers. One of the best indications of the growing tempo of American military production during the war is the following data on machine-gun production, covering the period July 1, 1940-Aug. 31, 1945:

Year        .50 Caliber(1)     .30 Caliber  Year     .50 Caliber     .30 Caliber
1940             5,155           3,633      1943        641,638         188,311
1941            49,479          27,672      1944        677,011         121,771
1942           347,492         314,839      1945        239,821          62,977

(1)The increasing preponderance of .50-caliber machine guns reflects
their growing use as aircraft and armored vehicle armament.

Shipping Losses

Allied merchant shipping losses during the war were as follows:

Year      Number of vessels      Tonnage
1939            221              755,237
1940          1,059            3,991,641
1941          1,299            4,328,558
1942          1,664            7,790,697
1943            597            3,220,137
1944            205            1,045,629
1945            105              438,821
----------------------------------------------------
Total         5,150           21,570,720

Of the 5,150 Allied merchant vessels sunk, 2,828 were victims of Axis submarines, principally German. The parallel German submarine losses (revised according to the latest British Admiralty assessment) therefore furnish an interesting in dication of the gradual Allied success in antisubmarine warfare:

Year       Loss
1939          9
1940         24
1941         35
1942         87
1943        237
1944        242
1945        151 
----------------
Total       785

Other German naval losses included 2 battleships, 2 battle cruisers, 3 pocket battleships, 2 old battleships, 2 heavy cruisers, 5 light cruisers, 44 destroyers, and 86 light warships and armed merchant raiders, as well as 1,377 minor and auxiliary warships and approximately 550 landing craft. Japanese naval battle losses included 10 battleships, 20 carriers, 38 cruisers, 115 destroyers, and 119 submarines. The rapid disappearance of the Japanese merchant marine is shown in the tonnage available: 6.1 million tons in 1941, but 1.8 million tons in 1945.

British Commonwealth naval losses from Sept. 3, 1939, to Aug. 15, 1945, including Allied warships operating under British control, comprised 4 battleships, 2 battle cruisers, 5 aircraft carriers, 5 auxiliary aircraft carriers, 33 cruisers, 154 destroyers, 90 submarines, and 138 light warships and armed merchant cruisers, as well as 1,307 auxiliary and minor warships and 1,326 landing ships and craft of all types. U.S. naval losses and gains during the war were as follows:

Type of vessel           Losses      New ships(1)
Battleships                2             8
Aircraft carriers          5            27 
Escort aircraft carriers   6           110
Cruisers                  10            48 
Destroyers                71           349 
Submarines                52           203 

(1) Part of this new construction, particularly escort aircraft carriers,
was transferred to Great Britain as lend-lease material.
