LONDON, April 20.

 Monday last the Guards destined for America, who were at Godalming and Guildford, marched, and those from Chichester on Tuesday for Petersfield, in their Way to Portsmouth, where the Transports lay ready for them to embark at this Day, except the Royal George Transport, which is to carry the Grenadiers only. If the Wind proved fair, they were expected to be all on board as this Day.
