Alan, Whether the 5 "Lost Brigades" ever made it to Vicksburg is questionable at best. Obviously they all didn't and "Retreating Joe" Johnston abandonded Pemberton and retreated over 16 miles with no Federals in pursuit. Quoting directly from Bowden and Ward's book, which is heavily footnoted, here are Lee's missing veteran brigades. Also remember that Jenkin's and Corse's brigades were from Picketts Division. The following numbers are reported on May 31,1863. Jenkins and Corse both pleaded personally with President Davis to be returned to the ANV. Jenkins was outraged that he would not be participating in the Pennsylvania Campaign.

"These five brigades amounted to more than 11,000 experienced infantry in 20 regiments and four smaller battalions. The strength's listed above are found in OR 18, pp 929, 1086. Figures for Evans and Corse are estimates based on prior returns. According to Corse (OR 27,pt.3, p. 893), on June 15, 1863, his command did not number "over 1,200 effective men." Cooke reported on June 20, 1863 (OR 27, pt.3, p.909) that the number of officers and other ranks present in his brigade was 2,486. See also returns for June 30, 1863 (OR 27, pt. 3, pp. 946-947).
